git-annex is definitely the tool you want for this job.
Great docs, amazing code, awesome community.
Quick start guide:
Install it with sudo apt-get install git-annex then it's on to managing your data just like you'd do with git.
git init
git annex init "main-backup"
git annex add # if you don't specify any paths, it adds everything
# it'll hash your files and store them inside the .git folder with their hash as their filenames
git commit -m "Add my most important files"

I'd like to keep a "snapshots/versions" of a folder containing lots of huge binary files. The folder contains all my backups made via rsync/rclone/scp/whatever.
Since the source can be corrupted/hacked whatever, I'd like to keep all the versions.
We all know git/subversion aren't made for files other than text and I wonder if there is a more general tool for that purpose.
I'll exclusively use linux.

Answering my own question in case somebody has the same problem:
I copied the following folders to the new laptop and I got all the projects with analysis results displaying
sonarqube folder
Sonar-scanner folder
.sonar folder (just in case)
.sonarlint (just in case)
.m2 (just in case)
|
I have Sonarqube Community Edition 8.4.1 (build 35646) running locally on Windows 10.
My company provided me with the new laptop and I need to move there all the sonar data (and scan results). I have spent few weeks analysing X amount of repos and will have to talk to each team about the issues that were found so it's really important to keep that data.
How can I do it?
PS: I am new to Sonar and I saw it first time in my life 4 weeks ago.
I have to move everything to cloud and I will not have 2 laptops at the same time to experiment.

You can install the same SSL certificate on both servers as long as your DNS server points to the live server. Both server should be configured with the same domain name. To automate this process, you can configure the two servers as a fail over cluster that will move the IP address from one server to another.

I have 2 Windows IIS servers (live and backup) running a host of Wordpress sites. The goal is to be able to switch to the backup server if the live server goes down. I can do this now by putting the live server's IP on the backup server. No problem, EXCEPT, the live server has a SSL certificate and the backup does not. So...is it possible to get 2 identical SSL certificates for 2 different servers from the same authority without causing any issues so that I can truely flip the IP addresses and everything runs smoothly?

I summarize the solution as below.
Windows task scheduler doesn't have permissions to the mounted azure file share drive. So we need to use the path https://[Azure_account].file.core.windows.net/storage/Backup to access Azure file share. Besides, if you want to implement auto-upload, you can use azcopy.
For example
Create a sas token for the file share
Script
azcopy copy 'C:\Program Files\Microsoft SQL Server\MSSQL14.SQLEXPRESS\MSSQL\Backup*.bak' 'https://[Azure_account].file.core.windows.net/storage/Backup/SQLBackup/[backup_file].bak?<sas token>
Create a schedule task

I have a server in which I'm running an SQL Server Express DB and an Azure blob i which I Upload each morning the backup of the SQL Server.
Now, I've been able to automate the backup via a mix of SQL query + batch file and I have it scheduled into my task scheduler to run each night at 9:00pm, but I would like to move also a copy of the backup from the server to the Azure Storage.
I've already tryed a batch file in task scheduler:
echo off
copy "Z:\Backup\SQLBackup\" "C:\Program Files\Microsoft SQL Server\MSSQL14.SQLEXPRESS\MSSQL\Backup\DailyStep_bck.bak"
But it doesn't work by itself, only if I run it manually.
Each day the current copy should replace the older one, I don't need retention of old bacups for now.
I've tryed also robocopy and it also doesn't work... could someone tell me what am I missin?
the task is running as administrator with the "Run wether the admin is loged in or not" option.
thanks for your help.

I uploaded a php script to a subdomain that I own, for testing and customizing purposes before it goes live (I had planned on moving everything over to the root domain when done).
Someone then suggested that I work on in Xampp instead as it is all locally installed and therefore much faster, etc.
Thing is, I had already customized the script a lot (mostly CSS but also uploaded graphics via the admin panel, etc) while it was up live on the web host, so I would like to run a copy of the most up-to-date version of it in Xampp and continue customizing it from there.
I downloaded a copy of all my files by FTP into htdocs > Test folder. I also downloaded a copy of the database via phpmyadmin and imported it via phpmyadmin into my localhost.
The big problem I have is when I try to access the scritp via localhost, the url immediately reverts back to the live url. How do I set it to link to the local host copy instead?
Thanks.

retaindays does not do what you are expecting it to do.
It prevents backup files from being overwritten, but it does not mean that old backups are automatically deleted.
See here
If you want a solution that will do both backup and cleanup, try Ola Hallengren's solution

I does not expect automatically deletion, but old backups are never replaced. Ola Hallengren's solution is too complicated to implement in our production environment.

By specifying noinit you are specifying append. But you don't want to specify init either! See Aaron Bertrand's comment Just create separate files, and clean them up with an independent process. If you use Ola's stored procedure, it will handle this for you. I strongly recommend looking into it, yes it has a lot of arguments that you can use, but you can also use it in a very simple way.

I am using SQL Server 2016.
I have setup SQL Agent for Full backup (Weekly) and Transaction Log backup (Daily).
Backup transaction log into a single file using:
BACKUP LOG [XXX] TO DISK = N'E:\SQLDB\Backup\XXX_Trans_Log.bak' WITH RETAINDAYS = 28, NOFORMAT, NOINIT, NAME = N'XXX-Transaction Log Backup', NOSKIP, NOREWIND, NOUNLOAD, STATS = 10
GO
What I expected is only 28 days transaction log backups will be kept. But now I just found All transaction log backups are kept. So the file grows to very large in size.
Is there syntax/option problems in the backup statement?
Or I should have to store in separate files?
What should I do now?

Did you check the documentation?
That is, if restoring documents to an existing database and collection
and existing documents have the same value _id field as the
to-be-restored documents, mongorestore will not overwrite those
documents.
So, unless you specify option --drop mongorestore will restore only the missing documents - this is the default.
In order to run a shard as stand-alone have a look at Perform Maintenance on Replica Set Members. Then you can use mongodump to get the dump from it.

I accidentally deleted some documents from our production database and want to restore them. So, I downloaded a backup shard from MongoDB cloud. I would like to re-add just the deleted documents without restoring the entire database. One suggestion was that I download the documents as a JSON file and upload that JSON file to the production db. I'm not sure how to accomplish this.
How can I run the backup shard, download the backup documents as a JSON file, and then upload them back to the production db?
Thank you in advance!

When you create a snapshot, you can specify a storage location. The location of a snapshot affects its availability and can incur networking costs when creating the snapshot or restoring it to a new disk. You will find the pricing for snapshot storage here.
This article describes how to create an image from your VM's root disk and export it to Google Cloud Storage or you can directly download it to your remote computer.

I've two VMs created at the Compute Engine session with hourly snapshot as backup copies. I never created any storage bucket, I wonder where do those snapshots stored and how does it count for the storage space charges?
And, is there a way I can backup the VMs to on-prem storage? e.g. can I use any API command to download the VM snapshot to my local storage as a backup of backup just in case Google Cloud screwed up.

I got Seagate Backup Plus Slim 1TB today.
I am planning to do mirror backup of my web projects from pc (C:\wamp46\www) to external drive (E:).
The toolkit app created folders on C:\ and E:\ both named "Mirror" as the syncing folder. Tested it and it works well.
But Seagate says:
The Mirror folders must each be named “Mirror” in order to sync. Do not rename the folders.
Now, how can I mirror backup my files under "www" folders if I can't rename "www" folder?
Is there any way?
Thanks!

I run 2 computers and sync the data between them using Google back up and sync which effectively stores everything on my google drive.
I have updated a class on my laptop and when I go on my desktop to continue it comes up with the old code however when I open the class file up on notepad it contains the updated file.
How do I get my eclipse to run the updated files I thought it should do this automatically since the file has been changed from the sync?

For me it sounds like a classic ETL job. You could use any programming language (like Python) or KNIME that reads from the source db (with an SQL query with a WHERE clause like your_date_column >= CURDATE() - INTERVAL 14 DAY) and write to a sink db.
You can then run it as a (cron) job in Windows/Linux and create each day a backup for the last 14 days but make sure that you also delete/drop the older backups if the size of the backups gets to big.

I have the shop live database. I need to have opportunity to make copies of this database but with orders data only for last 14 days. Database can be really big but almost 80 percent of data is order, payment and related tables. So we want to copy only last 14 days data of these tables, and all data of another tables. How it can be implemented?

If you have the debug APK you might have a shot. Have a look at this: Flutter debug Apk decompile to get source code
If you don't have the debug APK you are probably in trouble. The code on your phone is compiled and deliberately obfuscated, since usually you want to prevent someone with your app from getting the source code.
Really hope you can get it back. Good luck

You can use the command Get-AzRecoveryServicesBackupStatus in the if statement like below to check if is BackedUp or not:
(Get-AzRecoveryServicesBackupStatus -Name 'vmname' -ResourceGroupName 'rgname' -Type AzureVM).BackedUp
If we update your existing code like if backup does not exists it will perform the backup else it will show that Backup is already configured :
if (!(Get-AzRecoveryServicesBackupStatus -Name 'vmname' -ResourceGroupName 'rgname' -Type AzureVM).BackedUp) {
$vault= Get-AzureRmRecoveryServicesVault -ResourceGroupName "RgName" -Name "VaultName"
Set-AzureRmRecoveryServicesVaultContext -Vault $vault
Write-Output "Configuring Azure backup to $($vm.Name)"
$policy = Get-AzureRmRecoveryServicesBackupProtectionPolicy -Name "PolicyName"
Enable-AzureRmRecoveryServicesBackupProtection `
-ResourceGroupName $vm.ResourceGroupName `
-Name $vm.Name `
-Policy $policy
} else {
Write-Output "$vm.Name has already configured to Azure backup"
}

I'm building Azure runbook (powershell) which check if vm has backup enabled if it's not, it will enable it. I have problem with adding and building IF statement to make it better.
This is how I do it now and it works, but If vm has backup enabled, runbook will print a lot of red and thats not good. This is part of bigger runbook and those all are running inside on foreach.
$vault= Get-AzureRmRecoveryServicesVault -ResourceGroupName "RGName" -Name "VaultName"
Set-AzureRmRecoveryServicesVaultContext -Vault $vault
Write-Output "Configuring Azure backup to $($vm.Name)"
$policy = Get-AzureRmRecoveryServicesBackupProtectionPolicy -Name "PolicyName"
Enable-AzureRmRecoveryServicesBackupProtection `
-ResourceGroupName $vm.ResourceGroupName `
-Name $vm.Name `
-Policy $policy
Then I wanted to add IF statement there so if backup has been enable on vm, it would just skip it. The below command will print the results of backup ( true or false) but I don't know how to implement that into if statement so if results would be false, it would run the script block and if result would be true, it would just skip and print out $vm.Name has already configured to Azure backup.
Get-AzRecoveryServicesBackupStatus -Name 'VmName' -ResourceGroupName 'RgName' -Type AzureVM
Results of command
if ()
{
$vault= Get-AzureRmRecoveryServicesVault -ResourceGroupName "RgName" -Name "VaultName"
Set-AzureRmRecoveryServicesVaultContext -Vault $vault
Write-Output "Configuring Azure backup to $($vm.Name)"
$policy = Get-AzureRmRecoveryServicesBackupProtectionPolicy -Name "PolicyName"
Enable-AzureRmRecoveryServicesBackupProtection `
-ResourceGroupName $vm.ResourceGroupName `
-Name $vm.Name `
-Policy $policy
}
else {
Write-Output "$vm.Name has already configured to Azure backup"
}
So any tips how to do it? Can I do it somehow like this:
if (Get-AzRecoveryServicesBackupStatus -Name 'vmanme' -ResourceGroupName 'rgname' -Type AzureVM backedup -match false) ?

I don't think so. In order to restore a database, you'd need the same Oracle database version running on the same operating system as it was when that Oracle 7 database was up and running.
As it is an ancient database (~30 years old), it ran on an ancient operating system. If you have a support contract with Oracle, they will probably provide installation files. What about operating system? Today's machines are 64-bit; what was Oracle 7's database server? If it was e.g. one of Digital Alpha servers, you should visit a museum.
Not very optimistic scenario, I'm afraid.

I tried https://github.com/spatie/laravel-backup. it's very good and has many options to manage your backup.
I suggest if you want to show a better report of the backups that have been taken to your user in the software. Create a table and store additional information in it and use this table to display information to the user.

I'm using Laravel and I'm looking for a way to back up my database with php code. I want these backup files to be saved in paths such as other drives or usb drives (by the user's choice: so that the user enters the Windows path in the software, such as: "D: \").
I also use xampp to set up a server on Windows.
It is better to suggest if you know the standard Laravel package in this regard.

I have a simple backup script, which copies a folder to the backups directory each day, in the format Backup-YYYY-MM-DD.
I would like to make another script which will delete all of the backups which aren't from the first day of the month (all except those matching 'Backup-YYYY-MM-01')
I can't seem to find a way to do this, all i've found is the opposite of what I want: only delete those ending in x which doesn't really help.Or by using a temporary folder: move *-01 to 'temp', then delete all remaining folders this wouldn't be ideal since the file sizes are massive.
Thanks in advance

How do I delete all folders that don't end in a string, using batch?

Assuming you have an SSIS variable named @[User::DatabaseName]
Given that a backup command would look something like
BACKUP DATABASE [MyDB] TO DISK = N'\\Server\backup\MyDB\MyDB_backup_2020_05_06_020003.bak' WITH NOFORMAT,
NOINIT,
NAME = N'MyDb-Full Database Backup',
SKIP, NOREWIND, NOUNLOAD, STATS = 10
I'd create SSIS variables.
@[User::BackupTimestamp] string Expression something like
(DT_WSTR, 4) YEAR(@[System::StartTime])
+ "_"
+ RIGHT("0" + (DT_WSTR, 2) MONTH(@[System::StartTime]), 2)
+ "_"
+ RIGHT("0" + (DT_WSTR, 2) DAY(@[System::StartTime]), 2)
+ "_"
... repeat the above pattern to slice out hours, minutes, seconds into 2 digit entities
The purpose of this is to generate a string representation of the start time of the package with the level of time/date precision we want with our backups.
@[User::BackupCommand] This is going to be concatenated from other variables to build out the correct TSQL command.
"BACKUP DATABASE ["
+ @[User::DatabaseName]
+ "] TO DISK = N'\\\\double\\escape\\slashes\\"
+ @[User::DatabaseName]
+ "\\" + @[User::DatabaseName]
+ "_" + @[User::BackupTimestamp]
+ ".bak WITH NOFORMAT, NOINIT, NAME= N'"
+ @[User::DatabaseName]
+ "-Full Database Backup', SKIP, NOREWIND, STATS=10;"
As you can see, slashes are a bit of a pain as you have to double them inside Expressions. I typically create a variable called BackupPath which simplifies that bit.
Take the generated command, run it via SSMS and if it works, then you can simply wire up the SqlCommand/Text (property name aproximate) to that variable.
As for "add it to a backup plan", I don't know what plan your organization uses. I'm a fan of anything that backs up any database it finds as mechanically adding something to a process is a step that will have be missed at the most inopportune time. Ola's backup scripts, Minionware, etc

Now, I need to create an initial backup of that database (and then add it to a backup plan).

There is no export out of the box in SQL Server.
Assuming
Your table can be pretty big, since it looks like you and image of the table every minute.
If you want to do it all from inside SQL Server.
Then I'll suggest doing cleanup in chunks.
The usual process in SQL to delete by chunks is using DELETE in combination with OUTPUT statement.
The easiest way to archive and remove then would be having the OUTPUT to a table in another database, for that sole purpose.
so your steps would be:
Create a new database (ArchiveDatabase)
Create an Archive table in ArchiveDatabase (ArchiveTable) with same structure of the table that you want to remove.
In a while loop perform the DELETE/OUTPUT
Backup the ArchiveDatabase
TRUNCATE ArchiveTable table in ArchiveDatabase
The DELETE/OUTPUT loops will look like something like
declare @RowsToDelete int = 1000
declare @DeletedRowsCNT int = 1000
while @DeletedRowsCNT = @RowsToDelete
begin
delete top (@RowsToDelete)
from MyDataTable
output deleted.* into ArchiveDatabase.dbo.ArchiveTable
where dt < dateadd(month, 3, getdate())
set @DeletedRowsCNT = @@ROWCOUNT
end

Good Morning,
I want to print only the VM name so I can use it in the CLI from another program.
We use Backup-Plans according to the use of the VM. For this we write stuff like "Test" into the Vm's comments.
For example:
I have:
VM1 Test
VM2 Linux
VM3 Test
VM4 Test
The other command line (from cloudberry) handels Backupplans like this:
./cbb editHyperVPlan -n backupname -v VM1 -v VM3 -v VM4
The thing is, I want to make this automatically, so I dont have to put everytime someone makes a new VM the VM myself into the list.
BUT the Cloudberry CLI does not seem to support the Powershell Commands (it works over powershell).
So my idea was that I try to print VM1 VM3 and VM4 into the -v -v -v ... Is that somehow possible? Sorry if this is written confusing, I can't really explain it better..
Edit: I use this command to get the VM's I need: Get-VM | Where-Object { $_.Notes -like 'Test'}
|
Can I "print" the name of a VM in Powershell?

I need a PS script that would delete all the subfolders of a directory except for those:
everything from last 7 days
one newest folder from every week from past month
one newest folder from every month from past year
I am fairly new to PS and spent quite some time struggling already. Hate crying for help, but I suppose, this is the right moment.
Thank you!

Microsoft's recommended approach for such scheduled jobs/workflows is Azure Logic Apps
Microsoft have developed an extensive 'drag and drop' web UI to allow you to easily define actions such as moving data amongst storage containers, sending e-mails, etc. and then link these actions into workflows.
Here's a link to a useful quickstart guide.

I have a script copying a daily backup file to Blob storage using azcopy. On the Blob objects I want to create a lifecycle policy, like GFS, for the backups. Then I want to move older data (perhaps the yearly backup files) to colder storage automatically. Then I need to charge my client per GB storage and need a monthly report, maybe an e-mail, to our finance department with the month's maximum storage GB value. I will develop this and need guidance on where to start. Please point me in the right direction. As cheap and serverless as possible. I will answer my own question with the scripts etc to share the knowledge. Thanks!

In MABS documentation (https://learn.microsoft.com/en-us/azure/backup/backup-azure-microsoft-azure-backup) It's written that we can't install MABS on a computer which is node of a cluster so I just wanted to make sure that I'll need additional machine for that.

Can I install MABS in a server which is node in a wsfc cluster which I'm using for Availability group? If not then why?

If you are using composer (deprecated) and want to restore the backup from scratch, you have to also copy and restore the ENTIRE .composer folder located at ~/.composer.
Hope it helps.

I'm trying to do a full backup of a Hyperlerger composer instance, so as many tutorials said I've saved orderer and peer production folders, then restore it using Docker volumes but when I try to run componser rest server (or any other command) I get:
Connection fails: Error: Error trying to ping. Error: transaction returned with failure: Error: The current identity, with the name 'admin' and the identifier '26929e0ec17e93fcb6d22cc057d<>43061962760e7f23ebaf7df527', has not been registered
Haven't found any way to bypass it, I have admin and network cards used to create the first network, tried re-import with no luck.
Any other thing that I can try?
Thanks in advance

I'm using Hyperledger Fabric and now I'm trying to make a backup of the current situation and restore it on a different computer.
I'm following the procedure found in hyperledger-fabric-backup-and-restore.
The main steps being:
Copy the crypto-config and the channel-artifacts directory
Copy the content of all peers and orderer containers
Modify the docker-compose.yaml to link containers volumes to the local directory where I have the backup copy.
Yet it's not working properly in my case: when I restart the network with ./byfn.hs up I first have all the containers correctly up and running then, whatever operation I try and execute on the channel (peer channel create, peer channel join, peer channel update) fails with error:
Error: got unexpected status: BAD_REQUEST -- error applying config update to existing channel 'mychannel': error authorizing update: error validating ReadSet: proposed update requires that key [Group] /Channel/Application be at version 0, but it is currently at version 1
Is there anything I should do which is not mentioned on hyperledger-fabric-backup-and-restore ?

You have, basically, two options:
Implement your own logic by DynamoDB Steams and process your data by
your own logic
Use combination on AWS Glue for ETL processing and,
possible, AWS Athena for query your data from S3. Be careful and use
Apache Parquet format for better query performance and cache your
results somewhere else

In this case could you share more light on the DynamoDB Streams that you have mentioned, since it needs to be something simple and from what I can see it will pass the update of data at the moment of it happens to lambda, which means that there will be a thousand of files. The goal would be to simply make it so that when information in table "LetsDance" (for example) when an update happens between 1-30 of month it will not export it to S3 until the last day of the month in it's respective folder [ automatically create a folder of database name/month ]?

The goal that I wish to achieve is to generate a file of the table, so that afterwards that can be checked for data (monthly calculations). What I have done so far is to create a Backup using the PipeLine option from DynamoDB to an S3 bucket, but:
It is taking too long, the pipeline has been running for more than 24h since the table I am exporting is 7 GB in DynamoDB size (which is compressed and it will take even more time to finish with the backup);
I will need to do that monthly, which means that I will only need the data between first and last day of the month, while the PIPELINE can create a backup I could not find an option to make it so that only the changes in the table from specific timelines is exported;
The files that the Pipeline export are around 10 MB each and that means hundreds of files, instead of a couple (for example 100 MB files or 1 GB files).
In this case I am interested if there is a different way which I can make a full backup of current information and afterwards do a month to month on the changes that where performed (something like a monthly incremental) and not to have millions of 10 MB files.
Any comments, clarifications, code samples, corrections are appreciated.
Thanks for your time.

You need to follow this guide. Also, as a tip: keep out the execution logs from your project export, to gain space in your files.

Friends, good afternoon. Thanks for the tips and advice, but what happens, we have approximately 20000 jobs running and the guide presented by the Rundeck team itself was not very clear to me. The problem is by no means the guide presented, but me. I really lack stuff and knowledge about the rundeck, not least because I was introduced to this system recently. So my doubts about the best way to perform the backup.

I need your help on a subject.
I need to perform a backup of our Rundeck system and send it to a server in the GCP, but there are more than 90GB of information and I don't know how to make this backup.
All my attempts to compress using gzip, bzip2, xz and rsync have failed, the error is basically because the file is too big.
What would be the best way to perform the backup?
Could you give me suggestions?
Thanks in advance.

Simplest route I can think of would be (if the two DB are the same layout, table names etc) to download data, using a DataAdapter, into a DataTable and write it to disk with DataTable.WriteXml() then at the other end, DataTable.ReadXml() to get it from file back into a DataTable and write it into the destination DB with a DataAdapter. You'll need even fewer lines of code if you use strongly typed datatables (create a dataset)

I have a User Interface program written with VB.Net that collects instrumentation data from some PLC's and stores it in a MS SQL database. I need to be able to copy records from the DB based on a range of dates and save them in a file on a thumb drive. Then the file will need to be imported to a DB on another computer for analysis. I know SSMS can do a backup and restore but I don't think it can be based on a date range.

How can I copy MS SQL database data for a date range to be appended to DB on another computer?

Is there a way to backup the SQL Server to an external hard drive daily (automatically) through a procedure (query)? I am using SQL Server 2014
|
SQL Server - Backup server through
|
No, there is no such way.
Here is a related bugreport:
https://github.com/h2database/h2database/issues/2390
If you use the persistent database you can close the connection after execution of RUNSCRIPT command (make sure that you don't use DB_CLOSE_DELAY or use the SHUTDOWN command) and re-open it. The views will be initialized properly on startup.
If you use the in-memory database, the only workaround is to recompile your views with
ALTER VIEW VIEW_TEST RECOMPILE;
ALTER VIEW otherView RECOMPILE;
.....
|
I've a h2 schema with some tables and a view.
The view is defined by:
CREATE FORCE VIEW PUBLIC.VIEW_TEST(NAME_,STREET_) AS
SELECT
USER.NAME_,
ADDRESS.STREET_
FROM
PUBLIC.USER
LEFT OUTER JOIN PUBLIC.ADDRESS ON USER.ADDRESS_= ADDRESS.ID_
After dumping (via "SCRIPT TO ..."), within the dump file, the "CREATE FORCE VIEW PUBLIC.VIEW_TEST ..." is before the "CREATE TABLE ADDRESS ..." clause. This table is joined within the view.
The result is, that after restoring the schema (via "RUNSCRIPT FROM ...") the command "SELECT * FROM VIEW_TEST" returns a error that the referenced table "ADDRESS" is unknown:
View "PUBLIC.VIEW_TEST" is invalid: "Tabelle ""ADDRESS"" not found
Table ""ADDRESS"" not found [42102-197]"; SQL statement:
SELECT * FROM VIEW_TEST [90109-197] 90109/90109
If I drop the view and recreating it, everthing works fine, but I want to automize the dumping and restoring process.
Is there a way to set the ordering of tables and views?
What is the best way to ensure, that the view definitions are at the end of the dump?
Many thanks

Use pg_restore from the newer version to create a plain SQL dump file. Then restore to the older version from that dump file. Depending on what features you are using, the dump file may need to be manually edited before it will restore successfully.

I am trying to restore database from PostgreSQL Version 11 into PostgreSQL Version 10.
I am using Windows 7 (32-bit) so I can't use the latest PostgreSQL Version. So I am using PostgreSQL Version 10.
But I am taking backup from database of PostgreSQL Version 11.
Because of which I am getting error:
pg_restore: [archiver] unsupported version (1.14) in file header
So, is there any way I can restore my database in PostgreSQL Version 10.
It would be really helpful if any can show me a way out.

You can use S3, and not grant any users the action "s3:DeleteObject".
Enabling versioning in S3 will mean that you can recover previous versions in the event of accidental deletion. See S3 IAM.
AWS CodeCommit is Git code repository. You can store code there, including multiple versions. Identity and Access Management (IAM) allows you to deny or allow specific actions on code branches, including pulling, editing or deleting the branch.
You could also use something like QLDB, which is an immutable ledger.

I am looking for a cloud service where I should be able to store the data but the deletion or manipulation is not allowed by anyone in the firm. The main objective is to store the source code and other data into a storage where no one has write permission over the already present files but atleast one person has permission to store new files. This is to prevent intentional deletion of critical data.
Hope I am clear about my query. I would prefer if it can be done in AWS or Hetzner cloud.
Thanks

Your question is unclear, but here are a couple of basic technologies that you should consider:
(1) Set up another MySQL server which is a replication slave of the master. The two servers communicate so that the slave is always up-to-date.
(2) Use version control such as git to manage all the software that is installed on any server, and all versions and changes made to it. commit the changes as they are made and push the changes to an independent "repository," e.g. on (a private repository on a ...) public service such as GitHub or BitBucket.
(3) Arrange for all "asset files" to be similarly-maintained this time probably using rsync.

I have a primary server, where I'm running couple off websites.
A friend of mine has configured everything there. Im running Debian on my server.
ISPConfig (Where I manage all my domains, mails, ftp)
Apache
Mysql
PHPMyadmin
Now, I have very important websites which needs to up and running all the time and I want to purchase another server so if this one fails the other one should take over.
I'm planning to use DNSMadeEasy service..
I know I can use rcync to clone all of this but my question is:
How do I know what needs to be copied to the other files so I get all the configuration files of all different services i'm running.
Is there a way to clone on server to another or what is the best approach here?
Im super concerned that this server might go do, and I can not afford to have my website going do..
Any thought and ideas?

...but it is generating error
Without the exact error, it is hard to infer what could be the problem. Meanwhile, I don't really understand the way you are passing the credentials. Is there a specific reason why you don't use the relevant module parameters ? Did you try like this ?
- name: Run cURL commands
hosts: localhost
tasks:
- name: First task
uri:
url: http://IP ADDRESS:9200/_snapshot/TEST_backup/backupname
method: PUT
url_username: "username"
url_password: "password"
body:
indices: "index names"
ignore_unavailable: "true"
include_global_state: "false"
body_format: json
validate_certs: no
Note that I totally dropped the headers since body_format: json will automatically set Content-type: application/json (and we are not supposed to need the two others).
In case your service on the other end is not returning 401 error correctly on first connection for basic auth, you can try to add force_basic_auth: true and see if it does any better (see doc link above for more details).

I am trying to set up a automatic backup for my ELK indices. To do it manually I am using the below curl command.

-H 'Content-Type: application/json' \
-d'{ "indices": "index name", "ignore_unavailable": true, "include_global_state": false }'
Could you please let me know how the ansible curl structure will pan out for the same as per my idea it should be like below but it is generating error.

Not sure for HP-UX but maybe device you use is autorewind so you should change the device or use tar on this way:
tar cvf /dev/rmt/2m file1 file2
Or you can try to use
tar cvf /dev/rmt/2mn file1
tar cvf /dev/rmt/2mn file2
as this driver is not autorewind

The command that i perform for backup was tar cvf /dev/rmt/2m file1 and after that the file2
But when i use the command to view the file
tar tvf /dev/rmt/2m
that command show me that i have only 1 file backup ( the last file2).
Please can you help on this.
where is the problem ? The problem is on backup command or the command to view the file.

You need to write a program/script based on the Google Drive API https://developers.google.com/drive/api/v3/about-sdk
Or, try a third-party Google Enterprise data backup tool, like CubeBackup or Spanning.

In our company, we use Google Enterprise, and Shared Drives to store all our documents. After chatting with Google support agents, it seems there is no way to backup some of our folders and files.
We have two different needs:
- keeping a regularly syynchronized backup of some sensible files updated regularly
- backing up every month some files as they are on the backup date, and creating a specific copy for each monthly backup
Anyone has a way to do either of those things?
thanks

I myself answer...
by help of this link : Temporary Files Used By SQLite
that say :
"The WAL file is created when the first connection to the database is opened and is normally removed when the last connection to the database closes. However, if the last connection does not shutdown cleanly, the WAL file will remain in the filesystem and will be automatically cleaned up the next time the database is opened. "
so i close database just before backup and after backup open it again
protected void backupDB() throws IOException {
SugarContext.terminate(); //Close databse
String format = new SimpleDateFormat("_yyyyMMdd-HHmmss").format(new Date());
FileInputStream indb = new FileInputStream(new File(new File(Environment.getDataDirectory() + File.separator + "//data//ir.shia.mohasebe//databases//"), "sugar_example.db"));
File file = new File(Environment.getExternalStorageDirectory() + File.separator + "Mohasebe Amal");
file.mkdirs();
FileOutputStream outdb = new FileOutputStream(new File(file, "mohasebe_backup" + format + ".mbac"));
FileChannel channel = indb.getChannel();
FileChannel channel2 = outdb.getChannel();
channel2.transferFrom(channel, 0, ((FileChannel) channel).size());
channel.close();
channel2.close();
SugarContext.init(getApplicationContext()); //Open database again

I have a backup activity that user can backup the app database and restore it later...
for backup i just copy my app database.db file to sdcard ...
for restore i first delete database.db-shm and database.db-wal file if exist (because android 9 use them) and then replace database.db with new one.
restore function works fine in all android ver.
backup function also works in all android version, but in android 9.0 its not reliable!
because some new data that user has added is in cache files (database.db-shm and database.db-wal) and not applied to database.db
what should i do?
could i forcefully apply cache file to database.db and then backup it?
or ...

Generally this question should go to Server Fault. That is the reason for the close votes. But, there are only a few questions there about IBM i and no one there on a regular basis answers these questions.
So... No, a save file can only contain a save of objects from a single library at a time. So you cannot do go save --> 21 to a save file.
But you do not need to put a virtual tape image in a save file to move it off the system. Think of a virtual tape image like an .iso image that you could burn to a CD. It isn't really an .iso image, but it is stored in the IFS as a single file. These images can be FTP'd as is to any other system and added to an image catalog on that system. Or they can be stored on a server somewhere as a backup and then transferred again to a new system to be used in a restore operation.
You can find documentation on how to move virtual tape images to a different system in the IBM Knowledge Center.

Currently you can not restore a BAK (database backup) from SQL Server into Azure SQL DB singletons. You can do this into Azure SQL DB Managed Instance, however. There's not a lot of point of replicating your schema logically from SQL Server only to replace the database from a backup. Please note that "dump files" are actually something different - those usually refer to Watson dumps if there is a crash in the SQL process. This contains the memory state of the program when it crashed to aid in debugging. I assume you meant "binary backup" (aka BAK files).
You can read about the SQL MI restore option here: docs page for SQL MI BAK restore

Why not use Backup/Restore and then apply custom scripts to handle unwanted objects?
Having the option to modify to the metadata objects(users..) would result in a security exposure/risk. More on that: https://dba.stackexchange.com/questions/71608/security-implications-of-restoring-a-backup-from-an-unknown-source

I have a rather large database (130+ tables) that needs to be transferred from a live server to a dev server quite often. Both servers are SQL Server Express (ver. 14).
Backup/restore doesn't work because it transfers data, schema and other objects (user privileges), but users on both servers are not the same
Tasks/Generate scripts... would produce very large .sql file (400MB+) and the SSMS (ver. 15) on the dev server runs out of memory (win10_64/32GB)!?
I have a script that splits the database (on the live server) into several smaller databases, and then I can generate .sql scripts and transfer the data and schemas and combine them in the required database on the dev server. But, the problem is that I have to manually generate those scripts, and it's a time consuming task.
I was wondering if there is a more efficient solution to my problem?

I would propose to try installing Bacula Community open source product (www.bacula.org) and follow the guide from here. You only need to create a script that exports the DIT in a single file. Then you just need to create a job that backups this file with Bacula. The benefit of this solution will be able to backup something else from your infrastructure with Bacula later on, it's pretty much a universal system.

This is for automating the backup of ldap..My question was more for the method of backup.Like in your script you used ldapsearch..Also How do you restore this backup ?

There are some other resources that may be helpful, like this info on using bpipe to make the backups run directly to the SD (bacula.lat/db2-bpipe-backup-with-community-bacula/?lang=en). And this blog post is also showing how to integrate it all into Bacula (karellen.blogspot.com/2012/02/ldap-backup-with-bacula.html).

We have an openLDAP cluster running with 2 Master(producers) and 1 consumer. I read the below guides and got a good enough idea about using slapcat/ldapsearch with slapadd/ldapadd to backup & restore the data.
How do I clone an OpenLDAP database
https://serverfault.com/questions/577356/ldap-backup-with-slapcat-vs-ldapsearch
For me using ldapsearch with ldapadd worked on taking a backup and restoring it. However, I ended up changing the entryUUID, contextCSN, create & modifyTimestamp of the entries.
ldapsearch -x -H ldaps://ldap.server.net -D "dc=mycompany,dc=net" -W -b "dc=admin,dc=mycompany,dc=net" -LLL > ldapd-"`date +%Y%m%d`".ldif
ldapadd -x -c -H ldapi:/// -D "dc=admin,dc=mycompany,dc=net" -y "${PASSWORD_FILE}" -f "ldapd-"`date +%Y%m%d`".ldif
I wanted to check if this is a preferred way of doing a backup & restore operations or is there any better practices ?

It looks like you are using "-NotAfter (Get-Date).AddHours(8)"
This will make your certificate expire after 8 hours, the default is 1 year.

I'm trying to register Windows client machine to a Azure Recovery Services Vault with a powershell script.
I'm having this error:
WARNING: Vault credentials validation failed.
Start-OBRegistration : Vault credentials file provided has expired. We recommend you download a new vault credentials file from the portal and use it within 2 days.
These are my commands:
$cert = New-SelfSignedCertificate -certstorelocation cert:\localmachine\my -dnsname aly20-srv.xxx.onmicrosoft.com -NotAfter (Get-Date).AddHours(8)
$certificate =[System.Convert]::ToBase64String($cert.RawData)
$Vault1 = Get-AzRecoveryServicesVault –Name "rsvault-staging"
$CredsPath = "C:\temp"
$CredsFilename = Get-AzRecoveryServicesVaultSettingsFile -Backup -Vault $Vault1 -Path $CredsPath -Certificate $certificate
Import-Module -Name 'C:\Program Files\Microsoft Azure Recovery Services Agent\bin\Modules\MSOnlineBackup'
Start-OBRegistration -VaultCredentials $CredsFilename.FilePath -Confirm:$false
It seems that the vault credentials file created in "C:\temp" is not valid.
If I try to get it directly from azure portal and run "Start-OBRegistration" command it works.
What's the problem? How can I solve?
Thank you.

The AWS tool that you can use to build infrastructure again and again is CloudFormation. We call this technique Infrastructure as a Code (IaaC). You can also use Terraform if you don't want to use AWS Specific tool.
You can use either YAML or JSON to define the template for your infrastructure.
And, you'll be using Git to do templates change management.
Watch this reinvent video to clear the whole picture.

As I'm following a multi-instance deployment strategy opposed to a multi-tenant, I'm deploying my entire infrastructure again for every new customer. This results in a lot of work as I have to
Deploy a new API instance on Elastic Beanstalk + env variables
Deploy a new webapp instance via s3
Deploy a new file storage via s3
Deploy a new backup file storage via s3
Setup a new data pipeline backing up the file storage to the backup bucket
Mapping the API and web app instance to a new customer-specific URL (e.g. mycustomer.api.mycompany.com and mycustomer.app.mycompany.com) via Route 53 + CloudFront
...
Is there a way to automate all of this deployment? I've looked into CodeDeploy by AWS but that doesn't seem to fit my needs.

Found a cure to this, use the option:
/XA:SH
which stops copying system and hidden files - which are how the special attributes of the Document directory appear to be copied. Worked for me, I only wanted the data files.

I have a custom script I use for backing up my hard drive to a temporary external drive. It's a simply a number of robocopy lines (without /PURGE). I've having trouble with the windows documents folder. If I have a command: "robocopy C:\users\me\documents D:\backups\somerandomdirectoryname ..", every time it's done, Windows thinks that directory is a Documents directory and even renames "somerandomdirectoryname" to "Documents". It changes the icon, and then I can not actually eject the USB drive because Windows will not let it go. What is causing Windows to do this to me? Is there something I have to exclude to make it "just a normal directory" on my external device?

Your backup will be connected to the Default Policy if you have not connected it to something else.
Therefore, you should be able to change the retention of your backup by editing the default policy.

I have made a manual backup of an azure VM today, which should have been kept only for today. But now I am in the situation where it's needed for more than one day. Now while making the Backup I was asked for a retention time which I didnt change so it was set to 12.11.2019 which is either today ad 00:00 or tomorrow at 00:00 depends on Microsoft. I would like to change the retention time now and keep this backup for longer.
The Policies which can be set in azure seem only to be for backups which were mad by the retention policy.

Visor CLI shows how many primary and backup partitions each node holds.
By default, a cache is split into 1024 partitions. You can change that by configuring affinity function.

I have started using Apache Ignite for my current project. I have set up the ignite Cluster with 3 Server Nodes with Backup Cache count as 1. Ignite Client Node is able to create a primary Cache as well as Backup cache in the cluster. But here I want to know for a particular cache which is Primary node and on which Node the Backup Cache is stored. Is there any tool available or any Visor command to do so along with finding the size of each cache.
Thank you.

In Azure backup, first backup is always a full backup and the subsequent backups are incremental in nature.
For example:
1st day full backup (100 GB) on premise to Azure = Successful
2nd day only the changes/ churn rate will be backed up as incremental. Could be 10 GB churn rate/changes as compared to previous day. Likewise this will continue till the 7th day. On 8th day as per the retention policy, the first day recovery point gets deleted and the full backup is merged with the 2nd day incremental backup which becomes the oldest recovery point for you to recover your data. For this day if you restore you will get 100 GB data. Because there was no additional data added to the full backup just the changes within 100 GB were backed up as incremental on the 2nd day.
This same logic applies in your use case as well.
Hope this clarifies!
Let me know if this is confusing or you've additional questions for me that I can help with.

I can't understand the process of the merged very well, do you know some documents about this technology, and can I understand like that when full backup is merged with the 2nd day, the old dates which changes/ churn rate on the 2nd day will cover the old dates ? But if the changes/ churn rate on the 2nd day is additional data added to 1st day, it will change like below: (1st day: Full Backup 100GB → 2nd day: 10GB changed different to 100GB → On 7th day: the 2nd day recovery point just keep 10 GB→ On 8th day: the 2nd day recovery point increase to 110GB)? thanks

I saw a blog of Incremental backups on Microsoft Azure Backup: Save on long term storage. (https://azure.microsoft.com/ja-jp/blog/microsoft-azure-backup-save-on-long-term-storage/)
But I have some questions about the Azure Backup Retention rang process works.
As an example, let us take a data source, A, made up of blocks A1, A2, … A10, which needs to be backed up monthly. Block A2, A3, A4, A9 change in the first month, and A5 changes the next month.
When I set the backup retention range of two months, so after I finished the third backup, can I restore block A10? If I can, can you tell me the process? Because as I know, the data source without change had been deleted.
If it not deleted, as the picture shows, there will have two blocks A2 (the first backup and the second backup)? If this is right, the Total Space occupied will continue to increase.

Figured out a way to do this a little differently. Essentially instead of worrying about naming the backup table to start, I just rename it after it successfully is populated with the data snapshot.
create table backup like ops_weekly_sla;
INSERT INTO backup
select * from ops_weekly_sla;
SET @yyyymmdd = DATE_FORMAT(NOW(), '%Y%m%d%H%i');
SET @a = concat('RENAME TABLE `backup` to `ops_weekly_sla.',@yyyymmdd,'.backup`;');
PREPARE stmt from @a;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
Not only did this achieve my goal, bonus feature was that it did not disturb my timestamps for original data insertion or row updates. /wewt!

I have a table1 that has data uploaded to it every day. The source can be unreliable in format and structure, so to avoid headaches and downtime, I want to take a snapshot of table1 every day before the upload runs.
I want to name the backups table1.YYYYMMDDHHMM.backup. Straight up variables weren't working so I tried to use a prepare statement (which is completely new to me). Below is what does not work... Some sage advice would be appreciated.
set @a = concat('CREATE TABLE `ops_weekly_sla.',@yyyymmdd,'.backup` like `ops_weekly_sla`;');
set @b = concat('SELECT * from `ops_sla_weekly` INTO `ops_weekly_sla.',@yyyymmdd,'.backup`;');
PREPARE stmt from @a;
EXECUTE stmt;
PREPARE stmt from @b;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Issues related to installation of Acronis extension should be investigated with the help of Acronis support team.
Just a suggestion, you can try redeploying the VM to see if that lets you successfully install the extension. If issue persist, reach out to support and share below information with the technical professionals.

This might be a odd question but is it possible at all to make a backup or copy of my Recycle Bin, if not possible no worries.
Reason for asking : Some people deletes file and remembers 100days later they accidently deleted the file, then it's a bit harder to get back the file just from restoring the file from the recycle bin.
Thanks.

I figured it out:
Copy the backup file you want from your host to your container with: docker cp LOCAL_FILE CONTAINER_NAME:/etc/NEW_FILE where LOCAL_FILE is the file on your host that you want to copy over, CONTAINER_NAME is the name of your docker container, /etc/ is a default and already existing directory, and NEW_FILE is just the name of the file that's going to get the data of the LOCAL_FILE.
Go inside your Docker container file system with: docker exec -it CONTAINER_NAME /bin/bash and navigate to where you copied your NEW_FILE.
Make a new folder(name it "backup" for the sake of clarity) and extract the contents of NEW_FILE into it.
Restore the backup to a new database with: influxd restore -portable -newdb NEW_DATABASE_NAME backup
For any alternative options in the last step, go to the documentation here

I've recently backed up my Influx database from a docker container and have now a backup file in the format of .tar.gz. I wanted to import the data from this file into another Influx database that is also running inside of a docker container.
What I tried to do was using Chronograf and its "Write Data" feature to import the content of the backup since it supports .gz files, but it seems that Chronograf only supports files that are up to 25MB in size and this backup of mine is 70MB.
I've searched for other possible methods to solve this in the "Docker Influx Documentation" and "InfluxDB Shell Documentation". The only thing I found relevant was the "-import" option that is refenced in the Shell Documentation. I tried using it but to no avail. Any command that wasn't a direct query in the InfluxDB shell was rejected and all I got was an error message that said: ERR: error parsing query: found influx, expected SELECT, DELETE, SHOW, CREATE, DROP, EXPLAIN, GRANT, REVOKE, ALTER, SET, KILL at line 1, char 1
Just to be clear, I'm on Windows 10 at the moment.

For the first error, change
exec($command,$output=array(),$worked);
to
$output = array();
exec($command,$output,$worked);
Since the second parameter to exec() is a reference parameter, it has to be a variable, not an expression.

I can not tell you if the parameters are fine. What I could tell is that I would definitely prefer to use a real and reliable backup and restore software. Why is that:
backup and restore tools are designed for that exact purpose
backup and restore tools provide more features than the "naming" one, which actually reflects a retention time need: like beeing able to find the data to restore based on dates, search system and so on
backup and restor tools can come with support contrat that give you an insurance to be helped if needed.
There are many backup and restore tools and as I am an open source guy I would suggest to go with Bacula (https://www.bacula.org) or the enterprise version of it (https://www.baculasystems.com) accordingly with your enterprise SLAs, policies or requirements.

I need to make sure I am employing best practices while adhering to my company's requirements.
1. 7 days of data backups, that overwrite when the day repeats. I have the naming convention as DBNAME_DAYNAME.BAK. I achieved this with a cursor that dynamically builds the name.
2. Transaction log backups occur every minute and are named DBNAME_DAYNAME_MINUTEOFDAY.TRN. Similarly, these should overwrite when the 8 day starts in the cycle. Similar cursor is being used.
3. Copy data backups to network share. I am using CmdExec after each backup completes.
4. Copy log backups to network share. I am using Backup Log to Disk and Mirror to Disk.
I need to make sure my parameters are correct.
For the data file backups in step 1, I am using the following parameters:
WITH NOFORMAT, INIT, SKIP, REWIND, NOUNLOAD, COMPRESSION, STATS = 10
Then, I have a second step that copies the files to a network share:
Copy H:\BACKUPS\SQLDataFiles*.* """\192.xxx.xxx.xxx\sharepath\Directory*.*""" /Y
QUESTION 1: All of this appears to work. Are my parameters okay?
For the Log file backups, I am using Mirror to Disk, with the following parameters:
WITH FORMAT, INIT, SKIP, REWIND, NOUNLOAD, COMPRESSION, STATS = 10
QUESTION 2: All of this appears to work, but are my parameters okay?
Of course, as it usually happens, the whole process was rushed by leadership, and I have not actually done a restore test. I will soon but wanted to get a review of the parameters by this wise group. The parameter descriptions are not sinking in. Admittedly, administration is not my forte. The parameters I am using are copied from other code, and some seem to imply tape. There is no tape, only disk. If they are tape and it does not cause problems, that is fine. I just want to make sure that the files are overwriting, and that I can recover with this setup.

There are much of ways of doing that.
But, if you always work local and you need a simple way of doing that, you may take a look at run scripts if some specific usb device is plugged in.
Meaning that a simple backup script with tar would run if you plug in your specific backup hdd.
Take a look at udev rules in linux.
udev is a generic device manager running as a daemon on a Linux system and listening (via a netlink socket) to uevents the kernel sends out if a new device is initialized or a device is removed from the system. The udev package comes with an extensive set of rules that match against exported values of the event and properties of the discovered device. A matching rule will possibly name and create a device node and run configured programs to set up and configure the device.
Take a look at these posts:
https://unix.stackexchange.com/questions/65891/how-to-execute-a-shellscript-when-i-plug-in-a-usb-device

First of all, I don't mean version control such as git.
I do use git locally but, I'm trying to determine the best way to do back-ups of source code (as well as other app assets) in case of hardware failure or such.
I was thinking I could set up a script to tar my project folders, and encrypt them with gpg. I would then save the encrypted tar to external hard drives and to 1 or more off-site locations using a service such as amazon drive or dropbox.
Currently, I'm a sole developer so my thinking was that this method should be okay. But I wanted to get some input to make sure I'm doing this the best/most reliable way possible.
If there is a better approach to this that may be more applicable to small teams, then please let me know, as I'm more than happy to do the extra work implementing the approach.

I would like to backup an existing localfolder SQLite DB within my UWP app to the user's OneDrive on button click and then when the same UWP app is installed onto another PC by the same user, restore the database back into the UWP app so that they have the same data in all devices where they may install the UWP app. I don't need anything complex. Just sweet and simple C# code.

Tell me how to solve the problem with depersonalizing personal data of clients in the MySQL database. My task is to make personal data of clients depersonalized during backup - full name, email. There is an e-commerce CMS, and I want this data to be changed during backup. How to implement this? Are there any examples? I imagine this as data changes during backup on the fly. Another option is a copy of the database and data changes through sql queries, and then anonymous backup. Tell me how to do it right and if possible an example. Thanks.

As far as i have understood, i can't use pg_dump and pg_dumpall for incremental backups, so i want to use pg_start_backup and pg_stop_backup as part of my incremental script, and inbetween create zip and move the Data folder.
My issue right now is that i can't call either of them, because they are not recognized commands.
I have tried calling them in the following ways:
1.
pg_start_backup('label', false, false);
This does not work because pg_start_backup is not recognized as an internal or external command.
2.
SELECT pg_start_backup('label', false, false);
This does not work because SELECT is not recognized as an internal or external command.
3.
psql -h %PGHOST% -p %PGPORT% -U %PGUSER% -d %DATABASES% -c "SELECT pg_start_backup('label', false, false);"
psql -h %PGHOST% -p %PGPORT% -U %PGUSER% -d %DATABASES% -c "SELECT * FROM pg_stop_backup(false, true);"
This does not work, because it starts the backup in one context, and tries to stop it in another, hence throwing this error: "ERROR: non-exclusive backup is not in progress".
4.
psql -h %DB_HOST% -p %DB_PORT% -U %DB_USER% -d %DB_NAME% -f test.sql
This DOES work, but i need to put some batch logic between pg_start_backup and pg_stop_backup, and i don't want to have several sql files i need to call.
What is causing my issues, and how can i fix it?
|
Why can i call pg_dump but not pg_start_backup directly in my batch file?

You can write a scheduled lambda function that queries to find the number of views, then updates the backup table based on that query. Documentation for how to connect to a Redshift cluster from a lambda function can be found here.

Hi,i want to do it using a sql query
– Sam
Jul 22, 2019 at 18:57
Unfortunately there's no way to have a scheduled query with Redshift on its own... You will likely want to create a lambda to perform this query for you daily. This is of course assuming you don't want to perform the query manually every day :) You can find more here: stackoverflow.com/questions/42564910/…

We generate a lot of DDL views.I want to create a back-up of all the DDL views in the pg_catalog or information_schema which updates it self everyday.
For example:
If the number of views yesterday was 10 and I created 5 more views today, the backup table should update itself from 10 to 15 at a specific time.

Immediate problem: When I do a pgAdmin 4 restore I get "Stymied by idle_in_transaction_session_timeout" error.
I am on a MacBook Pro running macOS Mojave version 10.14.5, using Java and PostgreSQL. I use the pgAdmin 4 GUI, as I am not proficient in psql, bash, etc. I have a test database named pg2. As you can see from the attachment, PostgreSQL servers 9.4 and 10 have the identical databases. If I make a change in a database on one server, it will show also in the other server’s database. There is a third server, 11, in which there is only the postgres database.
I have tried psql and get errors (including timeout errors).
I have tried to Delete/Drop server 11, it will disappear but when I sign out of pgAdmin 4 and then go into pgAdmin 4 again the server 11 will be there again.
See the attachments for screen shots.
I expect the backup/restore to work: backup, then make a change to the database, then correctly restore to previous state.
I would like to have just one server, preferably 11 with only pg1 and the test db tempdb running in it. I thought that I could live with the three, for I am aware of my current capabilities and thus did not want to screw things up further. However, I suspect that the two servers 9.4 and 10 are the source of my current problem: receiving the idle_in_transaction_session_timeout error while doing a restore. Note: I did the backup using the server 10’s pg1 backup. Did it create 2 backups, one for 9.4 and one for 10?

I am using the script below to do daily backups. I need to add more folders to be included in the daily backup, and I would like to have them contained in the same zip file. How would this scripted be modified to backup multiple folders to the same compressed file?
#!/bin/bash
TIME=`date +%b-%d-%y` # This Command will read the date.
FILENAME=backup-xmltv-www-$TIME.tar.gz # The filename including the date.
SRCDIR=/var/www/html/wp-admin # Source backup folder.
DESDIR=/var/backups # Destination of backup file.
tar -cpzf $DESDIR/$FILENAME $SRCDIR
I have tried to add multiple source directories to the script, but only the last source in the list gets compressed.
SRCDIR=/var/www/html/wp-admin
SRCDIR=/var/www/html/wp-content
SRCDIR=/var/www/html/wp-includes
I have also tried to give the sources different numbers, but tar errors out to tell me to look at the tar help file.
SRCDIR1=/var/www/html/wp-admin
SRCDIR2=/var/www/html/wp-content
SRCDIR3=/var/www/html/wp-includes

You should change your code as follows
Your connection should be open before execution command.
T-SQL statement to backup the database should contain 'WITH INIT' keywords. If you execute your code multiple time, your BAK file will continue to grow.
So, try this one
Using con = New SqlConnection("Data Source=.\SQLEXPRESS;User id=sa;password=admin;")
con.Open()
Dim str As String = "backup database OFFICEMANAGEMENT to disk='C:\TMP\OM.bak' WITH INIT"
Using cmd = New SqlCommand(str, con)
cmd.ExecuteNonQuery()
End Using
con.Close()
End Using

And there is no exceptions? Very strange. Try changing the path. Put the backup file somewhere else.

I am using VB.NET with SQL Server 2012 Express in a software.
I provided facility to take a backup of a database from application itself with following code
Dim con = New SqlConnection("Data Source=.\SQLEXPRESS;Database=Master;User id=sa;password=admin;")
con.Open()
Dim str as string="backup database OFFICEMANAGEMENT to disk='C:\OM.bak'"
Dim cmd as new SqlCommand(str,con)
cmd.ExecuteNonQuery
con.Close()
When above code is run, no backup file gets created, and also no error is shown.
If I run the backup command with T-SQL in the SQL Server Management Studio, the backup file is successfully created.
Can anyone help with this?
Thanks

You can add "cpbackup-exclude.conf" in a global or user level.
Global:
/etc/cpbackup-exclude.conf
User level:
/home/username/cpbackup-exclude.conf
The entries would be like this:
*/backup-*tar.gz
*/backup-*zip
*/backup*gz
*/cpmove*

You can use pv, to make a progress bar for every file, as explained here:

I have a script which i can do a backup of entire system, but i can't see at what progress it is. I found many answers with progress-bar scripts but i don't know how to implement them into my backup script.
My backup script:
#!/bin/bash
Backup_system="Backup_$(date +%Y-%m-%d).tar.gz"
# Record start time by epoch second
start=$(date '+%s')
# List of excludes in a bash array, for easier reading.
excludes=(--exclude=/$Backup_system)
excludes+=(--exclude=/proc)
excludes+=(--exclude=/lost+found)
excludes+=(--exclude=/sys)
excludes+=(--exclude=/mnt)
excludes+=(--exclude=/media)
excludes+=(--exclude=/dev)
if ! tar -czf "$Backup_system" "${excludes[@]}" /; then
status="tar failed"
elif ! mv "$Backup_system" ~/Backups ; then
status="mv failed"

I think mysqldump is what you're looking for.
Export database A to SQL file to import to database B:
mysqldump --host=localhost --user=dbauser --password=dbapassword dba_name > /path/to/store/dba.sql
Import database A dump into database B:
cp /path/to/store/dba.sql | mysql --host-localhost --user=dbbuser --password=dbbpassword dbb_name
You can wrap these commands in a call to system() in a PHP script.

there is a way of doing incremental backups which is way simpler and way faster, create another bat file which will rename the backup file by and append a timestamp and schedule it for a time (maybe 5-10 minutes) from the backup time depending on the speed of your backup.
I did the following bat file and it worked:
cd C:\Users\delli5\Documents\backups
@ECHO OFF
start cmd.exe /C "ren "backup" "backup%date:/=-% %time::=-%""
and this was after I had scheduled another backup using a bat like the following:
@ECHO OFF
cd C:\Program Files\MongoDB\Server\4.0\bin
@ECHO OFF
start cmd.exe /C "mongodump -d backup -o C:\Users\delli5\Documents\backups"
@ECHO OFF
I didn't create replica sets but just did the normal mongodump way so you can try this out.

I am new to mongodb and I know there is no direct way for incremental backups in mongodb.
I had setup the Replicaset. after this, what are the steps that I need to follow for incremental backups
I tried the below way but it is giving the error.
db.fsyncLock() in secondary member
mongodump --host <secondary> -d local -c oplog.rs -o /mnt/mongo-test_backup/1 --query '{ "ts" : { $gt : Timestamp(1437725201, 50) } }' in secondary member.
I don't know the exact use of this command. but somehow it is giving the error.
I stuck at this step since I am facing the issue.
The error message is below.
2019-05-17T14:37:18.716+0000 E QUERY [thread1] SyntaxError: missing ; before statement @(shell):1:12
Please help me with this.

How to take the mongodb incremental backups after setting up the replicasets
|
I can't think of any risk.
However, there may be an even faster way...
Plan A:
Use a 4th machine to run the backup script. Or, at least, write the dump to a 4th machine. Any dump program is I/O-heavy, probably even I/O-bound. By writing the dump on another machine, you offload the Galera node's I/O.
I assume you take the node out of the cluster during the backup? And have gcache big enough so that it does an IST, not an SST, to resync?
Plan B:
Carrying things a step further, use 4 nodes instead of 3. That way, having a node offline has less impact and less exposure.
Plan C:
Use a 4th machine as a Slave to one of the nodes.
Questions... What is the geographical distribution of the nodes? If all three are currently sitting together, think about tornados, earthquakes, floods, etc.
What is the purpose of the backup? Will the backup data be geographically remote? (Note: that will add some delay to the backup method.)
|
I have a Galera cluster (MySQL) consisting of three nodes and am currently relying on mysqldump for backup. This is cumbersome, to say the least, as the database has grown over the years and is now approaching 20 GiB and mysqldump takes roughly half an hour to do its thing.
Percona xtrabackup seems to be promising and I have tried it out on a copy of the database on a single node with very positive results, where backup time is radically reduced.
What I have not been able to find out is if it is OK to install xtrabackup on one of the nodes (preferably the one running mysqldump today) and run that on the cluster database? I have read quite a lot on xtrabackup but nowhere have I found any information about any risks with running it on one of the cluster members.
|
Can I run Xtrabackup directly on one of the members in a Galera cluster?
|
For your issue, I just can say the property is not supported by Terraform. You can see it in the Azure REST API for Recovery Policy as property instantRpRetentionRangeInDays and use the request body like this:
{
"properties": {
"backupManagementType": "AzureIaasVM",
"schedulePolicy": {
"schedulePolicyType": "SimpleSchedulePolicy",
"scheduleRunFrequency": "Weekly",
"scheduleRunDays": [
"Friday"
],
"scheduleRunTimes": [
"2018-07-30T18:30:00Z"
],
"scheduleWeeklyFrequency": 0
},
"retentionPolicy": {
"retentionPolicyType": "LongTermRetentionPolicy",
"weeklySchedule": {
"daysOfTheWeek": [
"Friday"
],
"retentionTimes": [
"2018-07-30T18:30:00Z"
],
"retentionDuration": {
"count": 5,
"durationType": "Weeks"
}
}
},
"instantRpRetentionRangeInDays": 5,
"timeZone": "UTC",
"protectedItemsCount": 0
}
}
Or you also can use the Azure Template and it also shows in it. But you cannot find the property in the Terraform. So I suggest you can use the Azure REST API or Template to achieve it.

I have successfully created daily and weekly backup policies using Terraform and both work fine. The Azure Portal however shows a red mark under "Instant Restore" on the policy blade saying "Retain instant recovery snapshot(s) for" and the value appears as 2 days. I need to change this value to 5; however, I don't see an option to alter it in Terraform. I was wondering if I should use "azurerm_snapshot" resource type to change it or if there is a workaround available in TF for it.
resource "azurerm_recovery_services_protection_policy_vm" "backup_policy_weekly" {
name = "${var.RG4VM}-weekly-bkp-policy"
resource_group_name = "${var.RG4VM}"
recovery_vault_name = "${azurerm_recovery_services_vault.backup_vault.name}"
depends_on = ["azurerm_recovery_services_vault.backup_vault"]
timezone = "UTC"
backup {
frequency = "Weekly"
time = "18:30"
weekdays = ["Friday"]
}
retention_weekly {
count = "2"
weekdays = ["Friday"]
}
retention_monthly {
count = "1"
weekdays = ["Friday"]
weeks = ["Last"]
}
}
Expected: Snapshot set to 5, as it is the minimum value
Actual: 2
Thank you/Asghar

You will not be able to migrate your Google Cloud instances to AWS without a lot of work. The underlying system drivers are different. You will need to do a bunch of things to remove drivers and software and install new drivers and software plus change the format of the files. You can do neither while running on Google Cloud. You must complete these changes before you can import into AWS. This means that you will need to convert the Google image into a virtual machine running locally in your network, make the required changes, and then use the AWS tools to import into AWS.
My answer will only cover exporting VMs to a file. The format of this file is not compatible with AWS as mentioned above. This file does make for an offline, out of the cloud backup, that can be imported back into Google Cloud.
You cannot export Windows VMs at all. Only Linux VMs.
You can export a Linux VM to Google Cloud Storage. From there you can use any tool that you want to download the file to your desktop. The Google Cloud tool is gsutil.
First create an image of your Compute Engine VM using the gcloud compute images create command.
Next, export the image to Cloud Storage using the gcloud compute images export command.

From the configuration you have posted it doesn't seem that you are specifying what you want to backup.
Example:
<?xml version="1.0" encoding="UTF-8"?>
<phpbu xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://schema.phpbu.de/5.1/phpbu.xsd"
verbose="true">
<backups>
<backup name="BackupDB">
<!-- source -->
<source type="mysqldump">
<option name="databases" value="myDatabase"/>
<option name="user" value="user.name"/>
<option name="password" value="topsecret"/>
</source>
<!-- where should the backup be stored -->
<target dirname="/path/to/backup/directory"
filename="mysql-%Y%m%d-%H%i.sql"
compress="bzip2"/>
<!-- sync sftp -->
<sync type="sftp">
<option name="host" value="backup.example.com"/>
<option name="port" value="22"/>
<option name="user" value="user.name"/>
<option name="password" value="topsecret"/>
<option name="path" value="backup/someName"/>
<option name="passive" value="true"/>
</sync>
</backup>
</backups>
</phpbu>
The above will do a mysql backup and then it will transfer the backup file to a remote server via sftp.
You can check the documentation and an example of xml config:
http://phpbu.de/manual/current/en/configuration.html#configuration.xml

This specific error has nothing to do with this being a standby server.
Rather, you forgot to use the -U option to specify the database user, so pg_dump assumes it is the same as the operating system user.
Don't use the root user for anything but administrative activities!

I remember at the time of 16 years, the time can also access to the application of through itunes. The ipa file and then through the ipa file modification extension into the. Zip file, directly open the can get the current English local resources, and then from the Payload folder to find the app file, right-click the display file content, can be read into the application of more local resources, basic inside it will include the app icon resources and Assets inside pictures, and so on
Unfortunately, I also forgot that the specific time was 17 years ago. This function was cancelled by an update of Itunes. However, we can still get the.ipa file package of the App with the help of three party tools in MAC, such as PP assistant and iToos. Then the relevant local resources of the application can be obtained through the method I just described
l hope help you

Is it possible to extract an iOS application's icon from its files within a locally stored iTunes iOS backup? I've searched the backup manifest and app related files and can find the list of installed apps, but no icons. Currently I am using the domain name as an input to the Apple iTunes search API.
e.g.:
for "com.facebook.Messenger"
https://itunes.apple.com/search?term=Messenger&entity=software
Ideal would be to extract from the backup files directly.

It is not possible to do backup XML via bash via REST API.
I was informed by Atlassian team that this is not possible. They are working on it but solution is not ready yet.
Only way of exporting data is by backup and restore from database.

I'm wondering whether it is possible to export data into XML via bash. Of course I could make a dump from database but XML is being choose by procedure of migration which I don't want to change.
As far as I have noticed exporting via rest API is not possible.
Is it possible to do it another way? Plug-in?

As @wildpasser mentioned in comments, the best way to do this is following:
Import required table using different table name (particular table could be imported using psql COPY 'different_table_name' FROM 'file_name'
Update the desired columns of your table from the different_table_name
Drop different_table_name

Is it possible to restore the particular column from the PostgreSQL dump? I know that it is possible to specify the table to restore, but what about column from this table?

You should either backup ${ignite.work.dir}/marshaller directory, or call ignite.binary().type(KeyOrValue.class) for every type you have in cache to prime binary marshaller.

I’m trying to come up with a strategy to backup data in my apache ignite cache hosted as a stateful set in google cloud Kubernetes.
My ignite deployment uses ignite native persistence and runs a 3 node ignite cluster backed up by persistence volumes in Kubernetes.
I’m using a binaryConfiguration to store binary objects in cache.
I’m looking for a reliable way to back up my ignite data and be able to restore it.
So far I’ve tried backing up just the persistence files and then restoring them back.
It hasn’t worked reliably yet.
The issue I’m facing is that after restore, the cache data which isn’t binary objects is restored properly, e.g. strings or numbers. I’m able to access numeric or string data just fine. But binary objects are not accessible. It seems the binary objects are restored, but I’m unable to fetch them.
The weird part is that after the restore, once I add a new binary object to the cache all the restored data seems to be accessed normally.
Can anyone please suggest a reliable way to back up and restore ignite native persistence data?

Relying on timing is probably a poor idea because it will vary according to how much data needs to be moved, and how congested the machine and/or network might be. I suggest you either make your schedule very generous, or else implement some kind of locking mechanism.
Try this for your rsync:
flock /path/to/some/nfs/filename.lock rsync <args>
And this for your tape backup:
flock /path/to/some/nfs/filename.lock <mycmd> <args>
The flock command (f-lock) ensures that only one process can own the lock-file at once, and will sit and wait until it owns the lock-file before it launches the command you give it. As long as the sync and backup are launched in the right order then the backup will always wait until the sync is done.
The main gotcha is that you ever have a power-cut, network outage, or some other interruption the causes a stale lockfile to be leftover then you have to delete it manually before either job can ever run again (and if you don't notice quickly then there can be a whole bunch queued up).

I am using rsync from more than 1 year to sync production data to an folder on the nfs volume, once sync completed our NDMP backup / Tape backup schedule will start.
Situation:
Yesterday we observed that the rsync was still in process to sync file from production folder to destination folder, before completion of rsync command tape backup process was completed. Hence the tape backup data is inconsistent.
Question 1) how to find how much time rsync took to generate list of files which needs to be synchronized b/w source & destination folder?
I used below command to print the time stamp to identify how much time rsync took to generate file list before copying file process start.
rsync -avz --out-format="%t %f" --delete /opt/app_home/shared/data /opt/app_home/shared/plugins /opt/app_home/shared/tape-backup-rsync-shared_new/
However seeking guidance on how to determine the time taken at each stages of rsync process so that i can tweek my scheduled cron job execution times.

Changing the Access tier to Azure Archive Storage(if storing data in Blobs) would be your best option. A few notes:
The Archive storage tier is only available at the blob level and not at the storage account level.
Archive storage is offline and offers the lowest storage costs but also the highest access costs
Hot, Cool, and Archive tiers can be set at the object level.
Additional info can be found here:https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers

We are migrating from an on-premises virtual machine to Azure cloud. The virtual machine will eventually be decommissioned and we have many files and folders that we don't want to lose, like old websites and databases, scripts, programs etc.
We use an Azure storage account for storing and retrieving images via blob containers for the live websites.
Q: What is the best and most cost effective way to backup large amount of files unused in production, rarely accessed, from an on-premises virtual machine to Azure cloud?

Don't bother with PARTITIONing unless you have over a million rows.
A table with 8000 rows is 'tiny'; keep them all in a single table. If there is already a DATE or DATETIME column, you don't even need an extra column to indicate the "year". And you don't need id_table2 (etc).
If you want to discuss further, please provide SHOW CREATE TABLE and some of the queries.
|
I have a database that need to be archived one every year. The data from last year will some times needed to be used in the next year so i have a column year that can have 3 values (0 - from current year, 1-from last year to be used, 2-to saved but not used). The DB is as follows :
Table1
id,year ...
Table2
id,id_table1 ...
Table3
id,id_table2 ...
Table4
id,id_table3 ...
These are the tables that need to be archived where table1.year = 2 . The archived data needs to be accessible as well and needs to go back at least 2 years. The number of rows per year is around: Table1 - 50 rows; Table2 - 250 (Table1 x5); Table 3 - 2500 (Table2 x 10); Table 4 - 5000 (Table3 x 2);
I looked at partitioning but couldn't figure out how to group the four so that they could all move to a separate partition.

I'm going to assume that you consider the backup incomplete if at least one folder does not contain a file modified in the past 24 hours.
$refdate = (Get-Date).AddDays(-1)
$complete = $true
$results = foreach ($line in Get-Content "C:\Backup\sample.txt") {
$result = Get-ChildItem $line |
Where-Object { $_.LastWriteTime -gt $refdate } |
Select-Object Directoryname, Name, LastWriteTime,
@{n="Size (GB)";e={[Math]::Round($_.Length/1MB, 1)}}
if ($result) {
$result
} else {
$complete = $false
}
}
if ($complete) {
Write-Host 'Backup complete'
} else {
Write-Host 'Backup incomplete'
}

Loop through a text file which contains folder Locations
foreach ($line in Get-Content "C:\Backup\sample.txt") {
Get-ChildItem $line | Where {
$_.LastWriteTime -gt (Get-Date).AddDays(-1)
} | select Directoryname, Name, LastWriteTime, @{Name="Size (GB)"; Expression={[Math]::Round($_.Length/1MB, 1)}}
}
This way I am only able to get the files that were modified yesterday.
What I want is to list out the folders which does and does not have files modified yesterday.
If a folder contains files that were modified yesterday (modified date as yesterday), then list those File Names, Folder Name and their sizes(GB).
And also Write-Host as backup successful.
The same should go with folders which does not contain files with the modified date as yesterday.
Write-Host backup not complete.

Here is the algorithm and the code for it.
Algorithm:
1. Get the backup directory of the file connected to current opening file buffer.
2. Open the backup directory.
3. In the dired buffer, go to end of the buffer.
4. Search backward for the basename of opening file.
Code:
(defun backup-each-save-dired-jump ()
(interactive)
(let* (
(filename (buffer-file-name))
(containing-dir (file-name-directory filename))
(basename (file-name-nondirectory filename))
(backup-container
(format "%s/%s"
backup-each-save-mirror-location
containing-dir))
)
(when (file-exists-p backup-container)
(find-file backup-container)
(goto-char (point-max))
(search-backward basename)
)))

You can't exclude a table from a backup. That is kind of defines a backup, the whole thing, not part of it. You can however find some ways around this. One way you could do this is by creating a second database and copying all the data from your database except that table to this database and backup the copy. You could use replication to copy your data and exclude the table and backup the replicated database. The problem is that either of these might actually take longer due to the quantity of data in the rest of the database.

I reported this GitHub Issue #9.
I then made a minor change to the error reporting GitHub Pull Request #10 to work out that the error was a Too many open files error:

Just a note that if my pull request (only just submitted) is not merged (and a new binary released) you will need to build from my fork.
Which I then fixed with a ulimit change:

by increasing number of open files for the shell to 1024:

Background to Plan C
Code42 decided to terminate their "CrashPlan for Home" service. This means that after the shutdown date of October 22, 2018, CrashPlan will delete your backup on their servers, which is to be expected, but much more annoyingly, you will no longer be able to restore CrashPlan backups that you stored locally. Effectively, Code42 is reaching into your computer to break your backups for you.
PlanC is an open source project to enable restore from existing CrashPlan Home backups to be performed.
My Problem
However, when attempting to restore I received an error:
MacBook-Pro:CrashPlanHomeRecovery daniel$ ./plan-c-osx/plan-c --key 07B... --archive ./sg2015/642033544161964565/ --dest ./recovered/ --filename "J:/..." restore

The file referenced in the error appears to read OK, but the reported error provided no more information.

Just a quick answer to some of your question(for others, I will update later).
Some questions can be found here.
1.1 Where are the snapshots stored?
Share snapshots are stored in the same storage account as the file share.
1.2 Will it cost the storage capacity
As per this doc (The Space usage section) metioned: Snapshots don't count toward your 5-TB share limit. There is no limit to how much space share snapshots occupy in total. Storage account limits still apply.
This means that when you create a file share, there is a Quota option which let you specify the file max capacity(like 5 GB), if you total snapshots(like 10 GB) is larger than that max capacity, and don't worry, you can still save these snapshots, but the total snapshots capacity should less than your storage account's max capacity.
If my snapshot exceeds 200, what will it be? Deleted by itself or the new one can't be created?
if more than 200, an error will occur:
"Exception calling "Snapshot" with "0" argument(s): "The remote server returned an error: (409) Conflict.".
You can test it just using the following powershell code:
$context = New-AzureStorageContext -StorageAccountName your_accouont_name -StorageAccountKey your_account_key
$share = Get-AzureStorageShare -Context $context -Name s22
for($i=0;$i -le 201;$i++){
$share.snapshot();
start-sleep -Seconds 1
}
May I delete the snapshot which I want by Azure Automation (use the runbook to schedules it)?
This should be possible, I can test it at my side later then update to you.
And most of the snapshot operation commands can be found here, including delete.
update:
$s = Get-AzureStorageShare -Context $context -SnapshotTime 2018-12-17T06:05:38.0000000Z -Name s33
$s.Delete() #delete the snapshot
Note:
For -SnapshotTime, you can pass the snapshot name to it. As of now, the snapshot name is always auto assigned a UTC time value, like 2018-12-17T06:05:38.0000000Z
For -Name, pass the azure file share name
|
I have some questions about the Azure Files Share snapshot, if you know something about that, please let me know. Thanks.
1, Where are the snapshots stored? Will it cost the storage capacity and how about the cost of creates and delete snapshots?
2, If my snapshot exceeds 200, what will it be? Deleted by itself or the new one can't be created?
3, May I delete the snapshot which I want by Azure Automation (use the runbook to schedules it)?
4, If I use Azure automation and Back up (Preview) to deploy the Azure FileShare snapshot together, which snapshot will I get?
If you know something about that, please share with us (even you can answer one of them, I will mark it as an answer).
Thanks so much for your help.

Assuming this is for a replica set deployment with default configurations, back-up methods that create backups of a MongoDB system at an exact moment in time (i.e. atomic) would guarantee at a transaction boundary.
With MongoDB multi-document transactions only when a transaction commits, all data changes made in the transaction are saved and visible outside the transaction. Also worth mentioning as of MongoDB v4.0.x, there is only a single opLog entry for all the writes within a single transaction.

There are implementations of ActiveStorage::Service that save the image data directly to the database.
Here's one such implementation.
https://github.com/lsylvester/active_storage-postgresql
Usually not a good idea to store lots of binary in an RDBMS.
However, if it's relatively few and simplifies your architecture, it may make sense.

When Redis restarts, it resets the LASTSAVE time as the current time.
I actually need the unix timestamp of when the last backup was made and not the timestamp of when the backup was restored
You can get the last backup time by checking the dump.rdb file's last modified time.

According to Redis official documentation:
LASTSAVE Return the UNIX TIME of the last DB save executed with success.
However, when I execute LASTSAVE I get the timestamp of the last restored backup instead of the last DB save executed. In other words, if I did a backup yesterday and I restore it today, LASTSAVE will give me a timestamp from today.
My problem is that I actually need the unix timestamp of when the last backup was made and not the timestamp of when the backup was restored.

why does the value of LASTSAVE changes when I load a redis backup?

You can't restore a database that is in use because the restore would put it in an inconsistent state. You need to disconnect all active connections (including all SSMS query windows and other applications) from the database in order to restore it. If it already exists make sure to check "Overwrite existing database" on the Options tab of the restore window.
On a side note, up to you but I would recommend not using a '.' in the database name. It can get confusing when using fully qualified object names that include the database.

Does Dev.Web already exist on the server instance when you're trying to restore?

No. It did but I deleted it after getting it stuck in "restoring" state, and I have also checked the option to overwrite any existing databases anyway

As long as Dev.Web does not exist already, you changed the destination database to Dev.Web, and the physical file names don't already exist, then it should restore without problem. Can you post a screenshot of the restore window that is giving you the error?

I think I found the issue. Under Options, Tail-Log backup > Take tail-log backup before restore > Leave source database in the restoring state was checked off, so I think this is why it was complaining that the source database was in use

I have two sets of databases for my different testing environments (internal qa and uat). I'm trying to bring qa up to date by restoring it from the latest uat backups. I encountered an issue with the qa DBs getting stuck in "restoring" mode and ended up deleting them, so I'm trying to create a brand new database now by restoring from the UAT backup and changing the name, but it keep failing.
Restore database
Source: device > latestUATbackup.bak
Destination: database > change name from UAT.Web to Dev.Web
Files > check off Relocate all files to folder
Options: Close existing connections to destination database
"Restore of database Dev.Web failed. Access could not be obtained because the database is in use"
I tried taking UAT.Web offline but then it fails with the error "UAT.Web cannot be opened because it is offline"
Why would it matter if the database is in use when I'm using a backup? What do I need to do?

It is absolutely safe and commendable to run backups from a standby server.
If you use pg_dump, you may run into replication conflicts that make pg_dump fail. To avoid that (at the price of delaying replication), set max_standby_streaming_delay = -1.

I have this production database (let's call it database a) running in the production server A. I have a replication (let's call it database b) of this A db running in the server B.
Right now, I have a backup script running on the A server. It's burdening A with too much processing and networking ...
I would like to stop backing up the a db and backup only b with the same script. I would move the script currently running on A server to A0.
Theoretically both databases are equal, but I'm not sure if it is good practice and if it is safe enough.
What do you think? Is it safe to do backups only on replication databases instead of the production ones?
