A number of online storage services provide 1-2 GB space for free. Several of those have command-line clients. E.g. SpiderOak that I use has a client that can run in a headless (non-GUI) mode to upload files, and there's even a way to download files from it by wget or curl.
You just set up things in GUI mode, then put files into the configured directory and run SpiderOak with right options; files get uploaded. Then you either download ('restore') all or some of the files via another SpiderOak call or get them via HTTP.
About the same applies to Dropbox, but I have no experience with that.

I require a small space online (free) where I can
upload/download few files automatically using a script.
Space requirement is around 50 MB.
This should be such that it could be automated so I can set

I have a dynamic ip & have no tech on setting up a server.
Any help would be appreciated. Thanks.

I think that the best way is using mysqldump.
Normally I create a cron task to run in a time of little traffic, it generate a dump naming with a timestamp_databasename_enviroment.sql, so it verify if there are old backups and compact it.
I think that is a good form to do database backups.

If you do it in a time of low traffic, the impact is small, or even imperceptible. I have a application with 4.000 use for hour average and I user this scheme to backup my database. normally I run it on dawn.

I was wondering whats the best way to backup MySQL (v5.1.x) data -
creating mysql data dir archive
use mysqldump
What are the pro/cons for the above? I am guessing mysqldump has some performance impact on a live database. How much impact are we talking about?
We plan to take a backup every few hours, lets say 4 hrs. Whats the best practice around MySQL backups or database backups in general.

First of all if you want to enable remote connection to your server (I'm not sure if this is what you're after), Try this: http://support.microsoft.com/kb/914277 . You will also want to make sure the mixed authentication option is enabled.

I recently found this link which shows a great example of backing up and restoring a sql server database. However, my SQL Server only uses WindowsAuthentication and so it does not really require a UserName and Password. To be able to do this, I turned the line srvConn.LoginSecure = false; into srvConn.LoginSecure = true;
I was expecting to connect succesfully to the Server. However, this example returns an exception saying that it was unable to connect to the server.
Can anybody help me please? I have to learn this application for me to be able to apply the same concept to a project i'm working on. Thank you very much.

Once solution would be to use a version control system, such as Subversion, Mercurial, or Git. Depending on the types of files (binary or text), some systems work better than others.

I've been thinking about a model for saving snapshots of a windows filesystem. Obviously you only want to backup new files or files that have changed - for stuff that hasn't changed you don't want to make another copy. rshapshot http://www.rsnapshot.org/ (for linux) accomplishes this by creating a new snapshot directory for each save point and hardlinking to unchanged files.
Windows doesn't really have hard and soft/symbolic links as far as I understand, although it has shortcuts(?). What would be the equivalent link structure in Windows? Would such a versioning model work? Or would a different approach be better, such as storing the versioned backups in some kind of database? I notice that SyncBackSE http://www.2brightsparks.com/syncback/sbse-features.html has versioning - any idea how this is implemented?
Thanks
Edit: I've now had a look at SyncBackSE: the versioning feature does not mean a snapshot view - it's simply keeping old copies of a file with a prepended time stamp.

Are you positive it is only the big table with blobs? Try running the dump sans that table. Do that table individually and if it still gets stuck, break it up.
Create the inserts into 3-4 groups and see if any go through. Process of elimination will help narrow down if theres a row specific issue (I.e. corrupted data?) or if mysql is simply taking a while to write.
I'd advise opening up a second mysql shell or using phpmyadmin to refresh the table view and see if new records are being written. MySQL isn't verbose on its dumps. It may simply be taking a while to load in all the inserts.
|
I have a with mysqldumb created backup file. It's about 15GB and contains a lot of blobs. Max size per blob is 30MB.
mysqldump -uuser -ppass --compress --quick --skip-opt supertext > supertext.sql
Now when I try to restore the backup, the process just gets stuck.
mysql -uuser -ppass dev_supertext < supertext.sql
It get stuck while writing back the biggest table with the blobs. There is no error message and mysql is still running fine.
This is on a 64bit 5.1.48 community edition for Windows server.
max_allowed_packet is set to 40MB and is not the problem. I had that before.
Any other settings I could check or something I can monitor during the restore?
Didn't see anything special in the query or error log. Maybe there is a timeout?
Just FYI:
I've already posted this question in the MySQL Forum, but got no response.

There are many ways to do this. It really depends on how complicated your "database" is.
The simplest solution is to write to a text file in a CSV format:
import java.io.PrintWriter;
import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
public class FileOutput {
public static void main(String[] args) {
File file = new File("C:\\MyFile.csv");
FileOutputStream fis = null;
PrintWriter output = null;
try {
fos = new FileOutputStream(file);
output = new PrintWriter(fos);
output.println("Column A, Column B, Column C");
// dispose all the resources after using them.
outputStream.flush();
fos.close();
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Or, if you're looking for an XML solution, you can play with Xerces API, which I think is included in the latest JDK, so you just have to include the packages.

I used the verify command and I cannot find some of the revisions. When I delete it and run the svn hotcopy command again then they verify output now includes the missing revisions. I guess that means that it does not overwrite them. I cannot seem to find a flag that will let me overwrite the files. If no one else offers up an answer I will have to pick this one as being the right answer.
|
I have used SVN hotcopy to make a backup of the repository every weekday. When I looked at the Windows Scheduled Task logs I see that the job has run successfully. When I do a svnadmin verify I don't seem to only have a subset of the revisions. Do I need to delete the files first or is there an overwrite existing flag. svnadmin help hotcopy revealed nothing.

I can't think of any option in mysqldump that would skip the empty tables in your backup. Maybe the -where option but not sure you can do sth generic. IMHO a post-treatment in a second script is not that bad.

I have multiple large MySQL backup files all from different DBs and having different schemas. I want to load the backups into our EDW but I don't want to load the empty tables.
Right now I'm cutting out the empty tables using AWK on the backup files, but I'm wondering if there's a better way to do this.
If anyone is interested, this is my AWK script:
EDIT: I noticed today that this script has some problems, please beware if you want to actually try to use it. Your output may be WRONG... I will post my changes as I make them.
# File: remove_empty_tables.awk
# Copyright (c) Northwestern University, 2010

i = 0;
line[++i] = $0; getline
if ($0 ~ /-- Definition/) {
inserts = 0;
while ($0 !~ / ALTER TABLE .* ENABLE KEYS /) {
# If we already have an insert:
if (inserts > 0)
print
else {
# If we found an INSERT statement, the table is NOT empty:
if ($0 ~ /^INSERT /) {
++inserts
# Dump the lines before the INSERT and then the INSERT:
for (j = 1; j <= i; ++j) print line[j]
i = 0
print $0
}
# Otherwise we may yet find an insert, so save the line:
else line[++i] = $0
}
getline # go to the next line
}
line[++i] = $0; getline
line[++i] = $0; getline
if (inserts > 0) {
for (j = 1; j <= i; ++j) print line[j]
print $0
}
next
} else {
print "--"
}
}

How to remove empty tables from a MySQL backup file

I believe the only concern is that the Log Sequence Number (LSN) chain is unbroken. This will start with your full backup, but can also have as many subsequent transaction log backups as you need. You mentioned the database will be offline until the log shipping is configured, so you shouldn't have an issue with transactions building up on the primary until the backup finishes copy/restore. However, if you wanted to bring the primary online, you might have to take frequent transaction log backups to avoid running out of space as the transactions build up (depending on usage).
This is okay, because you could easily copy those transaction logs over to the secondary, restore them, then enable log shipping. As long as all the backups taken on the primary have been restored on the secondary, the LSN chain is maintained, so the first log backup that is shipped over should restore correctly. Time doesn't matter in this case.
|
We have a new filestream database that will be initially loaded with 65GB data, for which we'd like to configure log shipping to a remote (different continent) location.
For the initial setup of log shipping, is there any threshold for the time between the backup of the primary and it's restore onto the secondary? The new database will essentially be offline until we have the log shipping configured. Due to the size of the database, it may be some time (days) between the database initially being backed-up and then restored on the target. Will this be a problem?

You can start SQL profiler, then carry out the actions in Management Studio to display the information you require, then look in the profiler output to see what has been executed in the background to get you that info.
My guess is that these tables/catalogs are being queried:
sys.backup_devices
|
In SQL Server Management Studio (I have 2008), I can see the contents of the media i have backed up to, be it disk or tape. I can see information such as what files it currently includes, the dates they were backed up, etc... Is there a way to do this in T-SQL? I would like to specify a device (which is linked to a file location) and query it for its contents. Any thoughts?

DPM comes as a part of System Center and it makes use of VSS writers. In other words it is dependent on VSS service. You will face issues if VSS fails, DPM backup wont work. It also makes use of application writers for application specific backups(like MS SQL DB and Exchange Mailbox)
DPM is a complete backup solution of almost all Microsoft platforms be it VMS, Sharepoint,SQL DB, MAILBOXES, FILES. It also has backup to Azure and Backup to tapes to meet short term and Long term goals.

Hmm this is quite difficult to understand. Sounds like you should make a new MySQL table containing snapshots of the calculations and the time they were saved?

We have a web application that creates a dynamic PHP page with all the MySQL stored details a user has entered via a number a forms. So far so good, but we want this information stored some how to be refereed to at a later date, as an administrator can make changes to the data, which reflects on calculations that are worked out from this saved data.
When going back over this saved data we need to be able to see all the information submitted for that particular calculation, so if that data has changed we will see what is was relating to that calculation. Now we have thought about maybe a snapshot when the calculation is done, pdf of the webpage or something similar would do, but is this simple to do?
I hope this makes sense...

By default it will lock all tables; this stops anything being updated.
If you are using transactional engines exclusively (InnoDB) then you probably want to use --lock-tables=0 and --single-transaction
This will use a MVCC snapshot (effectively).
Please post exactly what error you're getting, as well as the command you're using.

I don't see why you can't just do:

The * globbing should provide the files in the sorted order, check with ls mydb-3Wed.sql-* that they actually are though.

Hi my database has started to go over 2GB in backed up size, so I'm looking at options for splitting the file and then reassembling it to restore the database.
I've got a series of files from doing the following backup shell file:
DATE_STRING=`date +%u%a`
BACKUP_DIR=/home/myhome/backups
/usr/local/mysql_versions/mysql-5.0.27/bin/mysqldump --defaults-file=/usr/local/mysql_versions/mysql-5.0.27/my.cnf
--user=myuser
--password=mypw
--add-drop-table
--single-transaction
mydb |
split -b 100000000 - rank-$DATE_STRING.sql-;
this prodes a sequence of files like:
mydb-3Wed.sql-aa
mydb-3Wed.sql-ab
mydb-3Wed.sql-ac
...
my question is what is the corresponding sequence of commands that I need to use for linux to do the restore?
Previously I was using this command:
/usr/local/mysql_versions/mysql-5.0.27/bin/mysql
--defaults-file=/usr/local/mysql_versions/mysql-5.0.27/my.cnf
--user=myuser
--password=mypw
-D mydb < the_old_big_dbdump.sql
Any suggestions even if they don't involve split / cat would be greatly appreciated

I then try to restore the SSP via central admin on the new server. It fails with an error relating to the fact that it cant find the .mdf files that it requires. It is looking in the location that they were on the original server.
Does the backup not take care of moving these .mdf files as part of the backup restore process?
Would appreciate anyone's suggestions.

If you want to avoid disruption to your site, the best method is to setup a replication slave to your server, and take backups from that. Using this, the method of backup becomes irrelevant, as the slave will simply catch up with the master when the replication is finished, and there will be no disruption to the operation of the master.
You can also setup your application to use the slave for read queries, to reduce load on the master.

Are there major advantages to InnoDB hot backup vs ZRM snapshots in terms of disruption to the running site, the size of compressed backup files, and speed of backup/restore on a medium-sized to largish all-InnoDB database?
My understanding is that InnoDB's approach is more reliable, faster, does not cause a significant outage when running, etc.

Linking the same question asked on MSDN: Azure SQL Database Backup Fails, cannot connect to the database.
Please see the Requirements and Restrictions details where this functionality is not supported, which I have listed below the applicable items that apply to your scenario:
The Backup and Restore feature requires the App Service plan to be in the Standard tier or Premium tier. For more information about scaling your App Service plan to use a higher tier, see Scale up an app in Azure. Premium tier allows a greater number of daily back ups than Standard tier.
You need an Azure storage account and container in the same subscription as the app that you want to back up. For more information on Azure storage accounts, see Azure storage account overview.
Backups can be up to 10 GB of app and database content. If the backup size exceeds this limit, you get an error.
Using a firewall enabled storage account as the destination for your backups is not supported. If a backup is configured, you will get failed backups.
If none of the above apply to you, then the issue is an IP Address issue in that you need to enable "Allow access to Azure services" in the firewall for your Azure SQL (logical) Server.
Additional troubleshooting can be performed by leveraging Application Insights to capture the backup failure event and then drill into the collected log detail to see what the specific error is.

I am experiencing a problem configuring the backup of an SQL database using Azure.
I have web application and an associated Azure SQL database. The app connects to the DB no problem. I have pasted the connection string provided to me by the Azure UI (Home -> SQL Databases -> My SQL Database) into the connection strings section of the configuration for the App Service (Home -> App Services -> My App Service -> Configuration). I created a backup of the App Service (Home -> App Services -> My App Service -> Backups -> Configuration) and ticked my connection string to be back up my database.
After about 20 minutes, the backup fails with the error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - No such host is known.)
I can connect to the database from the SQL Server Management Studio running on my laptop, and from code running on my laptop, using the server, username and password from the connection string, why can the backup not connect to the database?
Many thanks for any advice.

I have finished such a script recently, running it for influxdb and mongodb hourly by jenkins.
There are two folders to store the backups.
One named "hourly_backups" stores the latest 24 hourly backups.
Another one named "daily_backups" holds the earliest hourly backup of last 7 days.
After backup is successfully finished, it will clean the old files to control the total size.
It sounds easy but must be careful.
I agreed that bash better for use. But you can also do it in python as a training.
People who has questions about the backups scripts of these two dbs can discuss it with me.

I'm retracting my initial "It can't be done" response - it should be possible by using a series of plays, but it's not very pretty.
If you really need the backup file to keep the time-stamp, you might want to put in an official request on the developer mailing list.
Use the stat module on the initial file to retrieve the file timestamp
Register the backup file name in the return value backup_file from the file or copy module.
Use the command module to call the touch command to set the time of the backup_file to the original time. (The Ansible stat module does not adjust file timestamps.)

How to take backup of file without changing its time-stamp with Ansible playbook? I tried backup=yes but the problem is like it changes the timestamp os the file.
Code:- dest={{item}} state=absent regexp='TLSv1' backup=yes with_items: ('{{certs_dir.stdout_lines}}')

I have installed Duplicity on some AWS EC2 instances using the folowing command
yum -y install duplicity rsync gpg python python-devel python-pip -- enablerepo=epel
This was based on an approach described here
https://rtcamp.com/tutorials/backups/duplicity-amazon-s3/
However, whenever I try to run a duplictiy command, I get the following command
Traceback (most recent call last): File "/usr/bin/duplicity", line 42, in <module> from duplicity import log ImportError: No module named duplicity
Anyone have any ideas on how to solve this?

I want to create a cronjob for making a backup (sql dump) from my database and e-mail it to me. Setting up the cronjob and stuff works great and I'm able to use parts of my zend application :)
Unfortunately I cannot use exec() or system() on my server so now I'm looking for a way to get the same result. I searched everywhere with all possible descriptions I could think of, but without any results.
So in short:
I want to backup my databaseup
Preferably in .sql format (like export in phpmyadmin)
Using the Zend framework (so I can use my already loaded
application.ini settings for the database)
I cannot use exec() or system()
I'm completely stuck so really anything would help! Thanks in advance!

Partially Succeeded means that there were likely some files which could not be backed up, because they were locked for some reason. When this happens the backup process skips them and backs up the rest of the site and database if configured. You should be able to see which files were skipped in the log file. If for some reason you do not need these files backed up you can skip them by following the instructions in section “Backup just part of your app” here.

Turns out the problem was that to use RegLoadKeyW() The loaded hive needs to be somewhere writable. Since the shadow copy is read-only, it failed.
When I copied the mounted file outside the shadow copy it worked fine.

I'm creating a shadow copy and I want to mount a registry hive from that shadow copy using RegLoadKey() so I go over its content using the normal registry functions.
This usually works well except in certain machines where it doesn't work at all.
I create the shadow copy and get its mount point - something like
\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy8
I then call
RegLoadKeyW(HKEY_LOCAL_MACHINE, "\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy8\Windows\System32\config\SOFTWARE", "mntpoint");
This call returns 1009 - The configuration registry database is corrupt.
If I use CreateFileW() I can open this file successfully using that path so it is definitely there.
I've made sure that the shadow copy is created with the registry writer so I don't think that's the issue.
There's no difference if I create the shadow copy and try this after a reboot.
This only happens on some machines. on most it works just fine. I'm not sure what differentiates the machines it doesn't work on.
The machine is a windows 2008 64-bit.

The first thing to understand is why that setEqual method can't work: you need to know how identifiers work. (Reading that link should be very helpful.) For a quick rundown with probably too much terminology: in your function, the parameter restore is bound to an object, and you are merely re-binding that identifier with the = operator. Here are some examples of binding the identifier restore to things.
# Bind the identifier `restore` to the number object 1.
restore = 1
# Bind the identifier `restore` to the string object 'Some string.'
# The original object that `restore` was bound to is unaffected.
restore = 'Some string.'
So, in your function, when you say:
restore = []
You are actually binding restore to a new list object you're creating. Because Python has function-local scoping, restore in your example is binding the function-local identifier restore to the new list. This will not change anything you're passing in to setEqual as restore. For example,
test_variable = 1
setEqual(test_variable, [1, 2, 3, 4])
# Passes, because the identifier test_variable
# CAN'T be rebound within this scope from setEqual.
assert test_variable == 1
Simplifying a bit, you can only bind identifiers in the currently executing scope -- you can never write a function like restore0 that affects the scope outside of that function. As @Ignacio says, you can use something like a copy function to rebind the identifier in the current scope:
restore1

Specifically, I want to create a backup of a list, then make some changes to that list, append all the changes to a third list, but then reset the first list with the backup before making further changes, etc, until I'm finished making changes and want to copy back all the content in the third list to the first one. Unfortunately, it seems that whenever I make changes to the first list in another function, the backup gets changed also. Using original = backup didn't work too well; nor did using
def setEqual(restore, backup):
restore = []
for number in backup:
restore.append(number)
solve my problem; even though I successfully restored the list from the backup, the backup nevertheless changed whenever I changed the original list.
How would I go about solving this problem?

Docker images save "diffs" every commit you make, along with all previous versions of your image. This means that your process is guaranteed to steadily increase your final image size. To avoid this, instead of using docker save, you should use docker export instead (which receives the container as an argument, instead of an image).

right now I'm experimenting with Docker.
I have "installed" a Docker Debian Image.
In this Debian Environment, I installed a application.
Now, I do every night this:
docker stop (stop container)
docker commit (make container to an
image)
docker save (to save the image to an file, I do this to backup
the current work)
docker run (to start the container)
So as you can see, I try to create a "backup-solution".
It works perfectly. But the problem is, that the backup-files are getting bigger and bigger by every day.
Even without touchting the container for multiple days.
It used to be well under 10 gigabytes, but now it's already 20.
Why is that? What am I doing wrong?
Thanks a lot

you can write a simple script (batch file) that only zips the types of files you want. suppose, you want to zip all your .aspx, .cs, .config, .xsd files only,
suppose you have winrar installed in your c:\program files\winrar
and your project is in c:\project\MyBigProject
then, just open your notepad, copy paste this, and save as "script.bat" (dont forget the double quotes while saving, you need to save it with double quotes, so that notepad saves as .bat extention instead of .txt)
so to backup (in other words, to zip wanted files) :
"C:\Program Files\WinRAR\rar" a -r0 -ed MyBackup.rar c:\project\MyBigProject\*.aspx,*.cs,*.xsd,*.config
the syntax is like this:
"path to winrar folder" 'switches' "Name of completed rar file" 'folder to zip'
just make sure the paths are in proper order. the "a -r0 -ed" parts are switches, and you can find out all about the switches here:
http://acritum.com/winrar/manual/index.html?html_helpswitches.htm
I use the "Ignore files" switch (http://acritum.com/winrar/manual/index.html?html_helpswxa.htm) to ignore all files and folders that I dont want (with wildcards) and My project is about 86 mb, when It gets compressed just with code files, it comes up to 6mb.
its the best way to do it really. If you need more help, please ask!
edit: Also, Look into SVN (its free!) - I use svn too, and its really helpfull. there is even a free tool called AnkhSvn to integrate into visual studio. its just fantastic!

I would like to make a backup of my project, but the folder now exceeds 6.6 GB mainly through extra libraries like boost etc, but even if I just select the folders with my sources, I end up with big files like: .ipch, .sdf and potentially others. To make matters worse I use eclipse to code and VS to compile, so that adds to the mess, although I have the impression that only VS creates big files.
In case shit hits the fan I would like to be able to unpack one archive, and have everything in there like the project settings and solution files, and the sources so that I can easily open it again in VS. I can live with having to re-download boost or other third party libs.
How do you tackle this problem and do I need to preserve file like .sdf?
Answer:
Thanks for all the tips. I will now adopt the solution proposed by LocustHorde because that seems to fit my needs best. I simply want one file that I can take offsite as a safe backup (and I don't want to use an online service). Storing all versions of all files doesn't seem to work towards smaller and simpler and it would be a bit overkill in this case, although I will look to install some version control system because I have no experience with them and I would like to get some...
Final Answer
After having a good look I found that dishing out which files had to be ignored by the winrar archiving was still a hassle. I finally ended up installing Git out of curiosity and liked it. So I now have some of my projects in a local repository. From eclipse I can easily mark files and directories for being ignored, and to make a backup I use git-extensions to clone the repo. I still need to look at purging old versions, which isn't very userfriendly in Git, but seems to be possible at least and then i will just 7zip the folder up. In the worst case I just delete the git database and I just have the last version of my source files. Or maybe I can checkout to another directory. We'll see.

Is there a sensible way to backup Visual Studio C++ solutions without all the "extra" files the IDE creates?

The safest option would be to revert your development environment to SQL 2005, as that way no matter what your code will be compatible with your hosting environment. You should be able to install a separate 2005 instance on your box, which should save time (have only one of 2005/2008 active at a time for performance reasons). To get this configured, you might have to uninstall 2008, then install a 2005 instance, then install a 2008 instance.
With regards to data, you might want to look into the BCP utility for copying data in and out of the database. Once you get the hang of it, it is pretty quick and convenient.
|
I only have SQL Server 2008 (Dev Edition) on my development machine
I only have SQL Server 2005 available with my hosting company (and I don't have direct connection access to this database)
I'm just wondering what the best approach is for:
Getting the initlal DB Structure & Data into production.
And keeping any structural changes/data changes in sync in future.
As far as I can see...
Replication - not an option cos I can't connect to the production DB.
Restoring a backup - not an option because as far as I can see, you cannot export a DB from 2008 that is restorable in 2005 (even with the 2008 DB set in 2005 compatibility mode) and it wouldn't make sense to be restoring production over the top of my dev version anyway.
Dump all the scripts from my 2008 Database, Revert my Dev to machine from 2008 -> 2005, and recreate the database from the scripts, then just use backup & restore to get the initial DB into production, then run scripts through the web panel from that point onwards
Dump all the scripts from my 2008 Database and generate the entire 2005 db from scripts in production. then run scripts through the web panel from that point onwards
With the last 2 options, I'd probably need to script all the data inserts as well using some tool (which I presume exists on the web)
Are there any other possibile solutions that I'm not considering.

It's not possible. Your app isn't even capable of reading the documents from other apps. This is accomplished via sandboxing. Every read/write your application tries to do to the filesystem is checked by the kernel to ensure you're staying within your sandbox. The documents belonging to other apps are outside of your sandbox, so you cannot see them.

If what you're wanting is a backup of the current state of the files themselves (and don't actually want the full version history), use svn export instead.
If you are trying to back up the history, then I concur with Rohith's answer.

I need to take the backup of one folder of my SVN repository. For this I have tried with svndump and svndumpfilter commands but of no use.
Can any one please explain how to do this with an example.
Update:
I have a repository in that I have one folder say "Test". Apart from this "test" there are some more folders/projects in my repository. If I want to take the full backup of my repository its consuming more memory (30 gb) so I want to shift only the "Test" folder with the history to another repository so that I can take the regular backups of only the "Test" folder (new repository) as it will take less memory. (I don't need to take the regular backups of other folders except "Test")
How can I do this?

Is this an exercise your doing. If not, you should probably look at some of the production message queueing technologies (e.g. MSMQ for Windows) which supports persisting the queues on the disk and not just storing them in memory.
In terms of your requirements
1. has a backup on hard disk at realtime
Yes MSMQs can do that.
2. and can restore the backup
And that.
3. Can respond to massive enqueue/dequeue request
And this...

Go to your Time Machine drive in Finder and check the permissions of Backups.backupdb. If you see a red stop sign it means that the permissions are wrong.
Open Terminal and check out the permissions
$ sudo -s
$ cd /Volumes/Time\ Machine
$ ls -l
drwxrwx---@ 6 root wheel 204B Jul 9 16:26 Backups.backupdb
Not sure why the group is set to wheel (perhaps previous macOS versions had administrators in the wheel group as well?), but changing it to admin, assuming your user has Administrator privileges fixes the issue
$ chgrp admin Backups.backupdb
This seems to have fixed it for me. No need to change the rwx permissions. I am unsure if there is a Repair Permissions feature for Time Machine drives, as this has been removed from Disk Utility.

Have you entered a retention period?
When not using the incremental backup you have to specify the retention period in order for it to "stick".
Just to be on the safe side, you can't use "0" as this is reserved to incremental.

Artifactory 5.2.0: managing non-incremental backups

If the crontab syntax given above is the one you actually use, your cronjob isn't executed three times a day, but rather every minute of 12am and 8am and 4pm every day. Resulting in 60 executions during the given hours. Depending on the script it therefore might seem to run for an hour.
If the script runs 2-3 minutes you should see 2-3 tasks in parallel if you use the ps command during this period of time. You might also want to investigate syslog. There should be a log entry for each command crond is starting every minute.
Add the minute of hour when your cronjob should start to solve this issue (e.g. 12 if you want your cronjob run on the 12th minute of 12am and 8am and 4pm every day):
12 0,8,16 * * * /opt/maintenance/backup-databases.sh

i have a small bash-script to backup some MySQL databases. The script dumps out the databases from MySQL using mysqldump and than rsyncs the zipped dumps to another server on the LAN.
When I run the script directly from the command line, the execution time is roughly 2-3 minutes.
I added the same bash script to the crontab of the user root. This cronjob is being executed three times a day. I have the impression, that the execution of the script takes much much longer then (Up to an hour I guess).
Is there any way I can debug what’s going on behind the scenes? I want to find out why the execution takes so much more time.
The crontab-entry looks as follows:
* 0,8,16 * * * /opt/maintenance/backup-databases.sh

Why must you use the date embedded within the file name? The last modified date should be the same as the date embedded in the file name as long as the backup has not been modified since it was created.
FORFILES is one of the few Windows utilities that conveniently works with date arithmetic. Type FORFILES /? from the command line to get help on its usage.
forfiles /p "D:\Google Drive\Saves Backup" /m "*.rar" /d -7 /c "cmd /c del @path"
If you have a risk that someone could modify a backup, thus changing the last modified date, then the above will not work. Parsing and comparing dates is a pain in batch. You would be better off using VBScript.
|
So I've got a batch file that backs up a folder to my Google Drive directory, like so:
C:\Program Files\WinRAR\rar.exe a -r "D:\Google Drive\Saves Backup\%DATE%.rar" "D:\Documents\My Games\"
This makes a file called 30-Sep-12.rar (being run today) in the appropriate folder.
However, my question is this: Is there some way to go through said folder (D:\Google Drive\Saves Backup) and delete backups that are more than a week old, as determined by the filename?

You are using the file name, not the path for RESTORE. Try something like the following - only specify the path:

SQL2036N The path for the file or device "/home/db2inst1/GYCZPAS/PAS_BACKUP/GYCZPAS.0.db2inst1.NODE0000.CATN000" is not valid.
I used the same path during RESTORE that I used for the BACKUP command, but it fails. What could be the reason?

If you have some database on the system, it's ok that the size of the backup grows.
|
I've got a backup script that's supposed to backup the whole system, but it keeps increasing in size days after the backup. I've set to do one backup each day in crontab.
TIME=`date +%b-%d-%y`
FILENAME=backup-$TIME.tar.gz
SRCDIR=/
DESDIR=/home/backup
tar -cpzf $DESDIR/$FILENAME --exclude=/home/backup --exclude=/tmp --exclude=/sys --exclude=/dev $SRCDIR
Is there some other directory that is constantly changing that i need to exclude aswell?
Thanks in advance.

You could try using the Try and Catch method by wrapping the (create-7zip $_.FullName $dest) with a try and then catch any errors:
Try{ (create-7zip $_.FullName $dest) }
Catch{ Write-Host $error[0] }
This will Try the function create-7zip and write any the errors that many accrue to the shell.

I am still very new and I have for example one script to backup some folders by zipping and copying them to a newly created folder.
Now I want to know if the zip and copy process was successful, by successful i mean if my computer zipped and copied it. I don't want to check the content, so I assume that my script took the right folders and zipped them.
Here is my script :
$backupversion = "1.65"
# declare variables for zip
$folder = "C:\com\services" , "C:\com\www"
$destPath = "C:\com\backup\$backupversion\"
# Create Folder for the zipped services
New-Item -ItemType directory -Path "$destPath"
#Define zip function
function create-7zip{
param([String] $folder,
[String] $destinationFilePath)
write-host $folder $destinationFilePath
[string]$pathToZipExe = "C:\Program Files (x86)\7-Zip\7zG.exe";
[Array]$arguments = "a", "-tzip", "$destinationFilePath", "$folder";
& $pathToZipExe $arguments;
}
Get-ChildItem $folder | ? { $_.PSIsContainer} | % {
write-host $_.BaseName $_.Name;
$dest= [System.String]::Concat($destPath,$_.Name,".zip");
(create-7zip $_.FullName $dest)
}
Now I can either check if in the parentfolder is a newly created folder by time.
Or i can check if there are zip folders in my subfolders I created.
What way would you suggest? I probably just know this ways, but there are a million way to do this.
Whats your idea? The only rule is , that powershell should be used.
thanks in advance

It depends a lot more on your operational requirements than anything else.
All three will require shelling out to an external program. libpq doesn't provide those facilities directly; you'll need to invoke the pg_basebackup or pg_dump via execv or similar.
All three have different advantages.
Atomic snapshot based backups are useful if the filesystem supports them, but become useless if you're using tablespaces since you then need a multivolume atomic snapshot - something most systems don't support. They can also be a pain to set up.
pg_dump is simple and produces compact backups, but requires more server resources to run and doesn't support any kind of point-in-time recovery or incremental backup.
pg_basebackup + WAL archiving and PITR is very useful, and has a fairly low resource cost on the server, but is more complex to set up and manage. Proper backup testing is imperative.
I would strongly recommend allowing the user to control the backup method(s) used. Start with pg_dump since you can just invoke it as a simple command line and manage a single file. Use the -Fc mode and pg_restore to restore it where needed. Then explore things like configuring the server for WAL archiving and PITR once you've got the basics going.

I'm a new to PostgreSQL and I'm looking to backup the database. I understand that there are 3 methods pg_dump, snapshot and copy and using WAL. Which one do you suggest for full backup of the database? If possible, provide code snippets.

Seems that you are wanting a bash script to run backup on dynamic databases that are created in MySQL. You can add the mysql root user account information in my.cnf in the root directory or within the bash script under the # [ Define Variables ].
you will need to chmod the bash script with
$sudo chmod +x backupmysql.sh
This will allow you to run the script with the following command.
$sudo ./backupmysql.sh
You can name the script whatever you like. In this example, I named it backupmysql.sh.
Here is the bash script:
#!/bin/bash
# [ Define Variables ]
HOST=`hostname -s`
syslogtag=MySQL-Backup
DEST=/var/dba/backup/
DBS="$(mysql -u root -Bse 'show databases' | egrep -v '^Database$|hold$' | grep -v 'performance_schema\|information_schema')"
DATE=$(date +'%F')
#[ Individually dump all databases with date stamps ]
for db in ${DBS[@]};
do
GZ_FILENAME=$HOST-$db-$DATE.sql.gz
mysqldump -u root --quote-names --opt --single-transaction --quick $db > $DEST$HOST-$db-$DATE.sql
ERR=$?
if [ $ERR != 0 ]; then
NOTIFY_MESSAGE="Error: $ERR, while backing up database: $db"
logger -i -t ${syslogtag} "MySQL Database Backup FAILED; Database: $db"
else
NOTIFY_MESSAGE="Successfully backed up database: $db "
logger -i -t ${syslogtag} "MySQL Database Backup Successful; Database: $db"
fi
echo $NOTIFY_MESSAGE
done
If you have large files for backup, you can replace the statement in the bash script for the mysqldump to compress the file using gzip.
mysqldump -u root --quote-names --opt --single-transaction --quick $db | gzip -cf > $DEST$HOST-$db-$DATE.sql.gz
you can use gunzip to uncompress the file.

If I'm understanding you correctly you want to make a backup of your project? If you've never used version control before, now would be a great time to start! Version control will not only provide you with what you're looking for but many other great features. There's plenty of different SCM's available for you to choose froml; Git, SVN, Mercurial and so on.
Otherwise if all you want is to copy the project to another location, open your eclipse workspace folder (the directory you defined when you first started eclipse) and copy the project directory from there. Or do as MarchingHome suggests.

I need a backup that included uncommitted modifications because my developers don't like to commit often.

What do you all recommend for backing up git workspaces/clones?
|
On a *nix system, use a CRON job. On Windows, it's Scheduled Task... Either will execute a script at a given time on any (or a specific) day.
I'd recommend a better table design:
DROP TABLE IF EXISTS `example`.`stocks`;
CREATE TABLE `example`.`stocks` (
`id` int(10) unsigned NOT NULL auto_increment,
`name` varchar(45) NOT NULL default '',
`stock_value` varchar(40) NOT NULL default '',
`created_date` datetime NOT NULL default CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
This way, if you want to see the last 9 values for a given stock name, use:
SELECT s.name,
s.value,
s.created_date
FROM STOCKS s
WHERE s.name = ?
ORDER BY s.created_date DESC
LIMIT 9
|
I have wondered for a while now how to this. If I want to take weekly backups of all or many of my tables that stores values that changes every day in mysql. I also want to execute daily functions with php that update update values in my db.
I was thinking of making a stock investing function. Where I have fictional data as the value for various stocks, a value that changes randomly every day for every stock.
Maybe something like this for the last 9 days of the stock price curve.
CREATE TABLE `stocks` (
`id` int(11) NOT NULL auto_increment,
`name` varchar(40) NOT NULL default '',
`day_1` varchar(40) NOT NULL default '',
`day_2` varchar(40) NOT NULL default '',
`day_3` varchar(40) NOT NULL default '',
`day_4` varchar(40) NOT NULL default '',
`day_5` varchar(40) NOT NULL default '',
`day_6` varchar(40) NOT NULL default '',
`day_7` varchar(40) NOT NULL default '',
`day_8` varchar(40) NOT NULL default '',
`day_9` varchar(40) NOT NULL default '',
if I could execute a php function once a day that made an array of the last 9 days of values. Then just change the day_1 value and use array_push($array, "new_stock_price"); then update the db with the new last_9_days values.

how to set up daily php functions or mysql queries

You mysqldump command is like this :
/usr/bin/mysqldump --host=HOST --user=USER --password=PASSWORD TABLE --quick --lock-tables --add-drop-table
Looking at the manual of mysqldump, I would say that it will think that TABLE is actually the name of your database (quoting) :
There are three general ways to invoke
mysqldump:
shell> mysqldump [options] db_name [tables]
shell> mysqldump [options] --databases db_name1 [db_name2 db_name3...]
shell> mysqldump [options] --all-databases
Apparently, you have to put the name of the database before the name of the table you want to dump.
So, for instance, something like this might do the trick :
/usr/bin/mysqldump --host=HOST --user=USER --password=PASSWORD DBNAME TABLE --quick --lock-tables --add-drop-table
Hope this helps !
EDIT : I actually made a quick test, using "databasename.tablename", like you did :
mysqldump --user=USER --password=PASSWORD --no-data DBNAME.TABLENAME
I'm getting the same kind of output you have... But I also have an error :
mysqldump: Got error: 1102: Incorrect database name 'DBNAME.TABLENAME' when selecting the database
Which, I'm guessing, is going to the error output, and not the standard output (you are only redirecting that second one to your file)
If I'm using :
mysqldump --user=USER --password=PASSWORD --no-data DBNAME TABLENAME
Everything works OK : no error, and I have the dump.

I am trying to write a PHP program to automatically created backups of MySQL tables as sql files on the server:
$backup = "$path/$tablename.sql";
$table = "mydbname.mytablename";
exec(
sprintf(
'/usr/bin/mysqldump --host=%s --user=%s --password=%s %s --quick --lock-tables --add-drop-table > %s',
$host,
$user,
$password,
$table,
$backup
)
);
All that I get in the resulting .sql file is this:
-- MySQL dump 10.10
--
-- Host: localhost Database: mydbname.mytablename
-- ------------------------------------------------------
-- Server version 5.0.27
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
/*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */;
/*!40103 SET TIME_ZONE='+00:00' */;
/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
It seems fishy that the results list Database:mydbname.mytablename.
I don't know where to start looking. My host, in helping my set up the program initially, said I would need to deactivate safe_mode (was already done) and give access to the binary (I don't know what this means).
Since the host takes two days to reply every time I ask a question, I'd like to resolve this myself if possible.

mysqldump is sufficient
It will generate the SQL code necessary to rebuild your database and as the relationships are not special data (just logical coincidences between tables) it's enough to backup a database. Even by using mysqldump without the --opt param it will add indexes definitions so the contraints will remain

I would like to know how to backup my data from 2 separate tables (CATEGORIES and SUBCATEGORIES, where SUBCATEGORIES belong to a CATEGORY) in such a way that I can restore the relationship at a later time. I am not sure if mysqldump --opt db_name would suffice.
Example:
Categories:
| ID | name
-----------
| 1 | Audio
| 9 | Video
Subcategories:
| ID | category_id | name
-------------------------
| 1 | 1 | Guitar
| 2 | 1 | Piano
| 3 | 9 | Video Camera

Usually, in the mysqldump backup script, the views are first created as tables and then are then dropped at the bottom of the script as each view is being created.
Sometimes there is an error in this process because when a view is created there is a user used as DEFINER. This statement may fail because this user might not exist in the database.
Please verify that the view drop/create script exists at the end, write the error that you are getting (if you are getting) and run the import using the -v option for more logging.

I have a db in MariaDB 10.1.25 and in this, I have many tables and 20 views.

It looks like you have a few options with Windows VMs, including something called the Windows Backup Agent. This agent allows you to configure redundancy and backup schedule, along with some other properties that may improve your performance.
Another helpful resource I found was this page which just talks about planning your back approach, along with next steps after you work through this material.

I have an Azure Windows VM running a few SQL server databases. Azure premium offers automated backup, which is great. I am however not able to change the frequency of the automated backups, which now occur every 2 hours. These 2 hour scheduled backups result in performance issues when the server is running important SQL Server jobs.
Is there any way to alter the frequency other than creating manual backup jobs with the job agent? Within the Azure portal I can only change things like the backup retention, not the frequency.
Thanks in advance!

You are trying wrong command

and type password when prompt.

I'm trying to take a backup of a MySQL database using the following command:
mysql -u "username" -p "databasename" > "somename.sql"
After I enter the password, it doesn't show any output/error. It doesn't show the terminal prompt. No backup file gets created.
I've used the same command successfully before. But I have no clue why it isn't working now.
Any ideas?
I work on Ubuntu 14.04 LTS.

MySQL backup command not working

I guess it is the pipe that is giving this problem. You might be getting the exit status of
"gzip -c > /usr/local/bin/database.gzip"
You might have to split the dump and gzip part into two.
use
`mysqldump -u root -ppassword database1 > ./dump.txt`;
if ($? == 0){
`gzip -9 ./dump.txt`;
}
else{
die "errored";
}
|
When I perform following in perl, I allways get the error code "0". Even if for example the mysql database does not exist, or the password is wrong, etc.
@args = ("mysqldump -u root -ppassword database1 | gzip -c > /usr/local/bin/database.gzip");
system(@args) == 0
or die "Command failed: @args \nError Code: $? \n";
My goal is to catch any error of the mysqldump command, so I can make sure if the backup was successfuly.

You can create a CRON job which launches a shell code.
For instance if you want to inject a backup database:
mysql -u user -ppassword database < yourbackupfile.sql
Now if you want to create a dump:
mysqldump -u user -ppassword database > yourbackupfile.sql

There are more open source solutions that I could name, but for this application my choice would be rsync and a cron job.
Here is a good overview of some open source options (some are more desktop oriented).
EDIT
The nice thing about rsync, is it can directly sync the folder storing the repo. The downside of this approach is it could sync a corrupt repository. Doing a dump and storing incremental backups would protect you from this.
Despite what I recommended above, my personal preference would be to avoid subversion altogether. With a DVCS like git or mercurial, ever developer's has a full working copy of the repository that can be used to restore the copy on your shared server.

CentOS 5.3
subversion 1.4.2
I forgot to add. Currently the total repository size is about 5GB, but that will grow over time.
We have our source code and documents on our internal server running CentOS 5.3 and we are using subversion 1.4.2.
We are looking for a backup strategy. We want to perform daily backups. We have about 30 repositories to backup of differing sizes.
I could create a script file and recursively backup using svnadmin dump.
However, I am looking for an automated backup system that will run nightly say 12am each day.
Does anyone know of any backup systems that are open-source? I think my company is reluctant to pay for any system.
Many thanks for any advice,

You'll need this:

Then you can create a .cmd file to run it and schedule it using Scheduled Tasks. I can't give you an exact command line because your setup will be different from mine, but the docs are here:

One way to do something like this would be to use the day of the week in the filename:
backup-mon.tgz
backup-tue.tgz
etc.
Then, when you backup, you would delete or overwrite the backup file for the current day of the week.
(Of course, this way you only get the latest 7 files, but it's a pretty simple method)
|
I have created a shell script to backup my webfiles + database dump, put it into a tar archive and FTP it offsite. Id like to run it X times per week however I only want to keep the latest 10 backups on the FTP site.
How can I do this best? Should I be doing this work on the shell script side, or is there an FTP command to check last modified and admin things that way?
Any advice would be appreciated.
Thanks,

I have the following line in my .vimrc
set backup backupdir=~/tmp/vim//,~/tmp//,.//,/var/tmp//,/tmp//$
However, I cannot see a root directory in the line.
Why does my Vim make backups of my shell scripts with the extension ~ to my root?
Problem 2: my Zsh run my shell scripts at login which I have in my PATH. For instance, my "replaceUp" shell-script started at my root at login. I keep it at ~/bin/shells/apps by default.
Why does Zsh run shell scripts which are in my PATH at login?

I'm writing a script that would back-up my PrestaShop instance installed on my own server. I'm using Prestashop 1.7.7.4.
I suppose it is recommended to put your shop(s) in "Maintenance mode" during database dumping, to make sure nobody interacts with it. However, the only method of enabling the "Maintenance mode" I can find is using the administration panel, which of course requires manual intervention. It makes automatic backups impossible.
Is there any established way to enable "Maintenance mode" using a script/cli/api and not the administration panel?

The issue is that your backup database sample to disk='...' statement by default APPENDS the new backup to the backup device (backup file). As the result, you then have multiple backups stored in the backup file.
When doing restore, you are restoring the first backup.
To solve the problem, you can specify to override the content of the backup file by using the "WITH INIT" parameter:
BACKUP DATABASE sample to DISK='D:\Backup\sample.bak' WITH INIT;
More docs can be found eg. here

We are using a AWS ec2-instance for gitlab with omnibus installation, Recently gitlab has not been deleting the backup files and disk is filling up. I am not sure which log i should be seeing for this issue.
When i do sudo gitlab-rake gitlab:backup:create --trace
so there is no error message, what could be the reason for not deleting the old backups? Please point me in the right direction.
Deleting old backups ... done. (0 removed)

You can use pg_dump to export the data just from the non-user tables in the development environment and pg_restore to bring that into prod.
The -t switch will let you pick specific tables.
pg_dump -d <database_name> -t <table_name>

I have a site that uses PostgreSQL. All content that I provide in my site is created at a development environment (this happens because it's webcrawler content). The only information created at the production environment is information about the users.
I need to find a good way to update data stored at production. May I restore to production only the tables updated at development environment and PostgreSQL will update this records at production or the best way would be to backup the users information at production, insert them at development and restore the whole database at production?
Thank you

Best way to make PostgreSQL backups

For a start, to loop through all directories a fixed level deep, use this:
for dir in /home/customers/*/*/*/
A pattern ending in a slash / will only match directories.
Note that $dir is a lowercase variable name, don't use uppercase ones as they may clash with shell internal/environment variables.
Next, your conditions are a bit broken - you don't need to use a [[ test here:
if ! find "$dir" -maxdepth 1 -type d ! -mtime -36 | grep -q .
If anything is found, find will print it and grep will quietly match anything, so the pipeline will exit successfully. The ! at the start negates the condition, so the if branch will only be taken when this doesn't happen, i.e. when nothing is found. -name '*' is redundant.
You can do something similar with the second /0, removing the /1 and /2 and using /3 to test for any output. I guess the /4 part is redundant too.

I'm writing a script to check if there actually is a directory that has content and a normal size, and see if there is a directory older then 36 hours, if not it should alert me.
However I'm having trouble using the directories as variable.
When I execute the script it returns: ./test.sh: line 5: 1: No such file or directory.
I tried ALLDIR=$(ls /home/customers/*/ as well but returned the same error.
What am I doing wrong? Below is the script.
Thanks a lot in advance!!

Ingress cost is 0 for any amount of data, as mentioned in network pricing on this page. The PUT/POST operations though are charged at $0.10 per 10,000 operations as per this page. In short for ingress, data is free, operations are not.

Currently we are using Amazon AWS S3 as a backup solution for our servers. Amazon AWS clearly states: "All data transfer in - $0.000 per GB". With Google Cloud Storage I can not find a clear answer.
From what I can find the egress and interconnect data transfer is defined. Interconnect is of course not relevant here. Egress means for as far as my english and the dictionary goes meaning outgoing transfer.
So how is the incoming data measured or are only the number of POST / PUT operation's calculated?
Hope that anyone who has been using Google for a while can elaborate.

Problem
The function preg_quote() escapes regex special characters, including ( and ), so your subject string doesn't contain
define('DB_NAME', 'thedbname');
Instead, it contains
define\('DB_NAME', 'thedbname'\);
and your regex fails.
Solution
Just remove the preg_quote() from your code, like this:
if (preg_match_all("/define\('DB_NAME', '(.*?)'\)/", $content, $result)) {
print_r($result);
} else { // note: I added braces; it's better to use them always.
print "nothing found\n";
}
This works correctly and outputs:
Array
(
[0] => Array
(
[0] => define('DB_NAME', 'thedbname')
)
[1] => Array
(
[0] => thedbname
)
)

I want to create a script to backup all my Wordpress installations without having to mark all the directories.
I want to test for the existence of the file wp-config.php and create a database backup with the information in this file.
Here my script which always outputs "nothing found":
$content = file_get_contents($sub_dir . '/wp-config.php');
if (preg_match_all("/define\('DB_NAME', '(.*?)'\)/", preg_quote($content, '/'), $result)) {
print_r($result);
}
else
print "nothing found\n";
I want to do the same parsing with DB_USER, DB_PASSWORD, and DB_HOST.
Here's an example of the content in this config file:
../...
// ** Réglages MySQL - Votre hébergeur doit vous fournir ces informations. ** //
/** Nom de la base de données de WordPress. */
define('DB_NAME', 'thedbname');
/** Utilisateur de la base de données MySQL. */
define('DB_USER', 'thedbuser');
/** Mot de passe de la base de données MySQL. */
define('DB_PASSWORD', 'thedbpassword');
/** Adresse de l'hébergement MySQL. */
define('DB_HOST', 'thedbhost');
../...

The ~-suffixed file is a backup copy of the file, with the state it had before you started editing.
You can disable such automatic backing up.
You can also control various aspects of such backing up, including where backup files are to be stored -- see the Emacs manual, node Backup and its subnodes.
You can also remove all of the backup files in a directory at once, by visiting the directory using Dired: C-x d. After visiting it, use ~ to mark all backup files for deletion, then x to delete them. See the Emacs manual, node Flagging Many Files.

I discovered that it is possible to rollback my DB instance to a certain point-in-time
That's the approximate net effect, but your description is not precisely correct.
What's possible with Point-in-time Recovery is that you can create a new instance, with the data as it existed on your current instance, at the specified point in time.
Your current instance is not modified by this operation, so you're not actually rolling anything back.
Point-in-time allows you to specify any time >= the time of the first retained backup, and <= the "latest restorable time," which is approximately 5 minutes ago.
The binlogs are not "merged" when you specify an arbitrary time -- that's not how binary logging and restoration work. The new instance is created with the latest snapshot that occurred prior to the specified time, and then the binary logs from that point in time up until the time you specified are applied, consecutively, to the instance, in order to roll it forward from the snapshot to the desired point in time. Binlog entries after the specified point in time are simply not executed.
The end result is a new instance that represents the data on your instance as it existed at the specified point in time.
If you then want to actually replace the old RDS instance with the new one in your stack, you change the DB instance identifier on old (to something different) and new (to match the prior value from old) and the DNS entry is automatically updated so that your application can find the new instance at the old hostname.
Yes, 35 days is the longest retention period for automated backups.
You can modify the backup retention period; valid values are 0 (for no backup retention) to a maximum of 35 days.

I discovered that it is possible to rollback my DB instance to a certain point-in-time, via binary logging.
I can rollback to 5 minutes ago, but how do I see the previous PiT? Is this 10 minutes ago? What would happen if I select 7 minutes ago, would the binary logs of the two closest PiT merge?
A secondary question, is 35 days the longest retention period for automated backups? The list does not go further when modifying my DB instance.

Some services, like the experimental mysql service on Bluemix are not able to be accessed from outside of Bluemix. You can only access them from within a Bluemix cloud foundry application. If you are using this service , you will need to deploy a phpmyadmin application and bind it to that database to perform management operations.
If you are using other mysql services like cleardb, see Jeff's answer

'add each file to a collection

collection.Add fcount
Next fcount
'sort the collection descending using the CreatedDate
Set collection = SortCollectionDesc(collection)
'kill items from index 6 onwards
For i = 6 To collection.Count
Kill collection(i)
Next i
End Sub
Function SortCollectionDesc(collection As collection)
'Sort collection descending by datecreated using standard bubble sort
Dim coll As New collection
Set coll = collection
Dim i As Long, j As Long
Dim vTemp As Object
'Two loops to bubble sort
For i = 1 To coll.Count - 1
For j = i + 1 To coll.Count
If coll(i).datecreated < coll(j).datecreated Then
'store the lesser item
Set vTemp = coll(j)
'remove the lesser item
coll.Remove j
're-add the lesser item before the greater Item
coll.Add Item:=vTemp, before:=i
Set vTemp = Nothing
End If
Next j

I have a macro in excel that runs before save and creates a backup of an excel table with the actual date in its name.
These backups started to take too much space, so I have inserted another macro that deletes backups older than 14 days. The problem is that sometimes we don't save new copies for 2 weeks or months, so I need a macro that will leave only the 5 newest backups and delete the rest.
The current macro used:
'======================================================================================
'delete old backup
Set fso = CreateObject("Scripting.FileSystemObject")
For Each fcount In fso.GetFolder(ThisWorkbook.Path & "\" & "excel_backups" & "\").Files
If DateDiff("d", fcount.DateCreated, Now()) > 14 Then
Kill fcount
End If
Next fcount
'======================================================================================
backups are saved in this format:
ThisWorkbook.Path & "\excel_backups" & "\backup_" & Format(Date, "yyyy.mm.dd") & ".h" & Hour(Now) & "_" & ActiveWorkbook.name
so a backup looks like this: backup_2014.12.18.h14_[filename].xlsm
My question is: can this be modified somehow to delete only the oldest ones, and leave the last 5 newest of them? I have no idea how to start writing that.
Thank you for your time.

Use echo to store your command in the crontab file from the command line
$ echo "1 4 * * * /bin/sh /share/CACHEDEV1_DATA/your-backup-folder/backup.sh" >> /etc/config/crontab
This command will run backup.sh 4 minutes past 1 AM.
To make the crontab persistent during reboot, you have to execute this command
$ crontab /etc/config/crontab
Please note that you cannot save the script in /etc/, or /bin/ or some other directory outside of your HDD directories. In other words, always save your script in /share/CACHEDEV1_DATA/your-backup-folder. If you don’t, the script will be deleted upon reboot.
Restart crontab
$ /etc/init.d/crond.sh restart
Set correct permissions
chmod +x /share/CACHEDEV1_DATA/your-backup-folder/backup.sh
Wait for the cron to run, and see if it works

i have a problem, executing my script by crontab on a qnap nas.
it is very confusing, because other test scripts work AND executing this script manually works, too.
here is the script:

[[ -d /mnt/backup-cr/daily.1 ]] && mv /mnt/backup-cr/daily.1 /mnt/backup-cr/daily.2
#3
[[ -d /mnt/backup-cr/daily.0 ]] && cp -al /mnt/backup-cr/daily.0 /mnt/backup-cr/daily.1
#4

/usr/bin/rsync -av \
--stats \
--delete \
--human-readable \
--log-file=/mnt/backup-cr/logs/rsync-cr.$bakdate.log \
/share/cr/ \
/mnt/backup-cr/daily.0 \
MAILFILE=rsync-cr.$bakdate.log.tmp
echo "Subject: rsync-log for cr from srv" > $MAILFILE
echo "To: [email protected]" >> $MAILFILE
echo "From: [email protected]" >> $MAILFILE
echo "" >> $MAILFILE
/usr/bin/tail -13 /mnt/backup-cr/logs/rsync-cr.$bakdate.log >> $MAILFILE
echo "" >> $MAILFILE
echo "" >> $MAILFILE
cat $MAILFILE | ssmtp [email protected]
rm $MAILFILE
And here is my crontab entry:
15 0 * * * /share/CACHEDEV1_DATA/.scripts/backup.sh
The script has the executable-flag, and as I said other scripts within the same folder works.
Does someone has an idea? Because if this works manually on QNAP and also works in crontab on another UBUNTU server, then I think I am getting dumb and paranoid :-)

The concern would be a potentially inconsistent state if any database operation occurred while the backup image was being created. Some of the database transactions may not have been flushed to disk yet, still residing in memory.
Since mysqldump can use the internal state of the database, I'd recommend using a cron job to regularly perform a mysqldump, and then backing up the output of the mysqldump with Cloud Backups.
Something like the following for the cron job:
#!/bin/sh
mysqldump -h DB_HOST -u DB_USER -p'DB_PASSWORD' \
DB_NAME > YOUR_WEB_ROOT/db_backup.sql gzip -f PATH_TO_BACKUPS/db_backup.sql

Rather than running mysqldump (e.g.) every morning, would it be fine to just rely on the daily server image backups that Rackspace Cloud Servers do? Or, is there a future headache that I'm not seeing?

Here's what I would do. Let's say the app is called "HPlan", so you have a \app\HPlan folder on your Essbase server. Within the HPlan folder there are several subfolders for each database, such as HPlan, Capex, Wrkforce, and so on.
Stop the entire app using EAS
Move the entire contents of the app\HPlan folder to a temporary folder
Place the backup contents into the app\HPlan folder so that it looks the same as before. So if before you had \app\HPlan\HPlan\HPlan.otl and \app\HPlan\HPlan\HPlan.ind and so on, you would see those again.
Start the app and see if it works.
Try to login via Planning and see that it works.
This will only work assuming the app was never deleted from Hyperion Planning itself. If you recreated or created a new app in Planning itself then this won't work. In that case you would need to roll the database (SQL Server, Oracle, etc) back to a previous point so that you still had all of the metadata that's in Planning.
Good luck -- if this helps please mark it as helpful so that more people are encouraged to answer Essbase questions on Stack Overflow!

User has accidentally deleted Essbase application from the EAS Console.
An application with the same name was created.
We then used Hyperion Planning to recreate the database of the new application.
We have file system backup of all the directories of the deleted application.
How can we get all the data of the old application into the new one?
Thank you for help.

Try mysqldump with a simple shell script. It can be extended to dump tables. It now only dumps databases.
#!/bin/bash
USER="username"
PASSWORD="password"
OUTPUTDIR="./"
MYSQLDUMP=`which mysqldump`
MYSQL=`which mysql`
# get a list of databases
databases=`$MYSQL --user=$USER --password=$PASSWORD \
-e "SHOW DATABASES;" | tr -d "| " | grep -v Database`
# dump each database in turn
for db in $databases; do
# skip internal databases
if [ "$db" == "information_schema" ] || [ "$db" == "mysql" ]; then
continue
fi
# dump whole database
echo "$db"
$MYSQLDUMP --force --opt --user=$USER --password=$PASSWORD \
--databases $db > "$OUTPUTDIR/$db.sql.bak"
# get a list of tables inside database
tables=`$MYSQL --user=$USER --password=$PASSWORD \
-e "USE $db;SHOW TABLES;" | tr -d "| " | grep -v Tables_in_$db`
# dump tables
for tbl in $tables; do
echo "$db.$tbl"

I'm working on Mysql data backup and restore system but stuck that how to go with it.
An Option which i may think of
Table Wise Backup Method
Creating A Directory With Dateandtime and directoy will have one definition text file with all databases and its table names plus seperate file for each table contaning table structure and table INSERTS.
Table Wise Restore Method
Reading directory and definition file to Sort backups with respect to dates and table names and user can select either all tables or one specific table to restore.
I'll be using PHP for this purpose as i have to upload these backup files automatically on different servers.
Questions
1- Is above backup and restore method is valid?
2- Is there a way by which i can write single file for each Database but still have some way to restore only selected or all tables in database?
3- What are important points i must to keep in mind for such applications?
Please let me know if anything Ambiguous?

Okay, here's a weird one!
I have this nifty little 32gig thumbdrive that I keep in my wallet that contains all the latest of EVERY file I need to go about life on a computer. It contains all my BASH command references, everything from rubiks cube algorithms to PDFs I use for references and digital books and all the software I've ever written. Friend need their computer fixed all of a sudden? BANG! I got it covered with the software in my left pocket. Sweet huh?
Well I want to keep track of every change I make to the repo as well as have constant backups of it. Git works pretty well for this, except that it copies all my files and inflates the repo's size drastically! This isn't really a big problem but it is annoying. I know Git is used for software repos and I'm cool with that (Thats what I primarily use it for anyways)
So I was thinking, could I somehow as a git nub use git to record changes I made to the repo but NOT keep a running copy of every actual change but only keep the HEAD version? So when I do a push/pull the repo would be backed up with all my comments but ONLY what is in the active directory tree within the flash drive would be saved in the Git repository? So there wouldn't be duplicate binary entries, if I removed a .exe file it would log it but get rid of the file forever?
Maybe there is a better way of doing this without using git? For instance I WAS using 7ZIP to compress and make backups manually, then saving them to a cloud server for backup redundancy. That was time intensive and much more annoying than a simple:
git add .
git commit -m "changes"
(git gc)
git push
Any help would be greatly appreciated!

Thanks in advance for any help in this matter

DB2: How to backup a DB2 database?

Why not just do what every unix , mac , window file has done for years -- create a lockfile/working file concept.
When a file is selected for edit:
Check to see if there is an active lock or a crashed backup.
If the file is locked or crashed, give a "recover" option
Otherwise, begin editing the file...
The editing tends to do one or more of a few things:
Copy the original file into a ".%(filename)s.backup"
Create a ".%(filename)s.lock" to prevent others from working on it
When editing is achieved, the lock goes away and the .backup is removed
Sometimes things are slightly reversed, and the original stays in place while a .backup is the active edit; on success the .backup replaces the original
If you crash vi or some other text programs on a linux box, you'll see these files created . note that they usually have a dot(.) prefix so they're normally hidden on the command line. Word/Powerpoint/etc all do similar things.
|
I need to modify a text file at runtime but restore its original state later (even if the computer crash).
My program runs in regular sessions. Once a session ended, the original state of that file can be changed, but the original state won't change at runtime.
There are several instances of this text file with the same name in several directories. My program runs in each directory (but not in parallel), but depending on the directory content's it does different things. The order of choosing a working directory like this is completely arbitrary.
Since the file's name is the same in each directory, it seems a good idea to store the backed up file in slightly different places (ie. the parent directory name could be appended to the backup target path).
What I do now is backup and restore the file with a self-written class, and also check at startup if the previous backup for the current directory was properly restored.
But my implementation needs serious refactoring, and now I'm interested if there are libraries already implemented for this kind of task.

version control seems like a good idea, but actually it's a bit overkill since it requires network connection and often a server. Other VCS need clients to be installed. I would be happier with a pure-python solution, but at least it should be cross-platform, portable and small enough (<10mb for example).

Are there a modules for temporarily backup and restore text files in Python

I presume that you mean that you want to be able to restore the data after user has somehow deleted the application and re-installed it again. Since each application has its influence inside the bounds of its sandbox, the only sane option would be to use server. In regards to simply answering your question - there is no way to do it as you've described.

i want to take the backup of all the data in the database of my iphone app in dropbox and restore it later.here the main problem is there is too much data in the app so if i am using sql queries to fetch data from sqlite3 database and storing it into the file and again reading data from that file and inserting it to database.can anyone suggest that how can i improve that or what is the best way to do that?

I currently have this setup at work. We use a customer hosted SVN server that at times has had some connectivity issues. We also want to make sure we have a local copy of things as well. We setup a SVN repo locally, and then run the svnsync command that is executed as a result of a continuous integration service to sync changes from the remote repo to the local mirror. You can read more about the svnsync command here. This generates an exact replica of the repo as it basically plays back the changeset into the mirror. This is also helpful for us in that if the connectivity "issues" return, we have a readonly repo available to pull working copies from to continue work until connectivity is restored ( you can do a svn switch/relocate to work off the mirror while the master is down ). This may be more complex then you are looking for, but I love the setup we have and it has saved my bacon more than once. Figured I would share an option. Good luck

We have a SVN server here that over the years has accumulated hundreds of thousands of revisions and reached a size of >40 GB. We'd like to do a continuous backup on the repository, but it just takes too long to dump or copy the whole repository to our backup server each time.
Is there a way to add the latest revisions of the repository to an existing dump file automatically? I know with the --incremental option this can be done manually, but I was wondering if there was a command that would essentially work like so:
svnadmin dump repo --revision dumpfile_latest:repo_latest --incremental >> dumpfile
Here dumpfile_latest would be the revision number of the latest revision of the backup (named dumpfile) and repo_latest would be the latest revision number of the repository I am backing up (named repo). Thanks for any suggestions!

This is what I did to get the database and other folders to automatically sync to my USB drive every time I plug it in:
Install SyncToy made by Microsoft.
Add a folder pair to copy from the DB folder to the USB drive.
Filter files to only the files you want to copy.
Create a batch program with the content below called SyncMe.bat and save it on your USB drive
Open Event Viewer from the Control Panel.
Navigate to Applications and Services Logs > Microsoft > Windows DriverFrameworks-UserMode > Operational
Clear the log to make it easier to find the right events.
Plug in the USB drive.
Refresh the log, find the latest event that is specific to that USB drive, right-click, and Attach Task To This Event.
Add an action that runs the SyncMe.bat program you created
SyncMe.bat contents (update to reflect your paths and file names):
@echo off
if exist "G:\SyncMe.bat" goto fileexists
goto nofile
:fileexists
"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\OSQL.EXE" -S computername\instancename -E -n -Q "master..sp_detach_db 'DatabaseName'"
"C:\Program Files\SyncToy 2.1\SyncToyCmd.exe" -R
"C:\Program Files\Microsoft SQL Server\100\Tools\Binn\OSQL.EXE" -S computername\instancename -E -n -Q "master..sp_attach_db 'DatabaseName', 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.InstanceName\MSSQL\DATA\DatabaseName.mdf','C:\Program Files\Microsoft SQL Server\MSSQL10_50.InstanceName\MSSQL\DATA\LogName_log.ldf'"
goto end
:nofile
echo SyncMe.bat not found on G:\
goto end
:end

I have a small SQL database that is on my development PC only. I'd like to make frequent backup copies of it to a thumb drive. If I could have it do it automatically on a schedule when the thumb drive is detected, that'd be even better. What's a good way to do this?

output.write(buffer, 0, length);
}
output.flush();
output.close();
in.close();

It throws an exception like permission denied I don't know what permission will i give. Anyone tell me? Thanks in Advance.

The transactional backup interval likely refers to how often transaction logs for your TFS databases are backed up. The schedule you choose will probably depend on how busy your repository is.
At my current client there are six developers, and we share some of the load for source control between VSS and TFS (we're transitioning). Corporate policy says we must backup transaction logs every hour during business hours, and an additional one at midnight. Our local backups are on a four-day retention cycle with off-site backups lasting years.
I would make a decision based on how much work you'd want to lose if your repository was lost and your working copy was destroyed simultaneously (natural disaster?).
|
I'm in the process of setting up a backup plan for a Team Foundation Server. I downloaded Power Tools for TFS and I'm using the Backup Plan Wizard that was included in that pack. I am now at the step where I'm supposed to decide how to schedule the backups and I have no idea what to choose for my setup.
I get what everything means, except Transactional Backup Interval.
I would appreciate suggestions for a good schedule. What I would like to achieve is being able to restore and still look back a few versions, if possible. The minimum backup I would like to have is the latest version.
It might be important to add that I got to choose "Backup retention days" earlier and set that to 30.

For windows batch scripting xcopy (native to windows) or robocopy (a free download in windows) both work extremely well.
An example xcopy script (in a .bat file):
@echo off
:: /L = list only.
:: /v=Verify, /y=No prompting /s=subdirs /z=Network mode (supports bad)
:: /i=Tells xcopy dest is folder /f=Display names /d=Copy only changed
echo Backing up projects...
xcopy e:\projects h:\projects /V /Y /S /Z /I /F /D
It will even support orphaned files (if you delete something from your source you no longer need a copy in the backup). Xcopy is typically fine for your needs until you deal with sync between NTFS and Fat32 file systems - the later only has a 2 second resolution and problems with daily savings time so you occasionally run into issues: (a) on time change day you might not get a backup of a changed file - depends on change-regularity of course or you might get a backup of all files even though none have changed (b) because of time resolution some files may backup even though they haven't changed.

I'm trying to create a script that will automatically backup a complete directory tree. I also want it to work for incremental backups. Basically, it wil work like this:
If file is in both source and destination and they are different, source file will be copied
If file is in both source and destination and they are the same, nothing will be copied
If file is only in the source, source file will be copied
If file is only in the destination, destination file will be deleted.
I'm still new to shell scripting and I'm not sure how I could implement this. Any ideas? Windows batch scripts would be better, but shell scripts that run on Cygwin are also fine.

I use getmail to periodically download the email by POP to a set of folders on my backup drive. GMail can be configured such that it doesn't delete or archive emails when they're downloaded, so it has no effect on the web interface.

What's a good way to backup old emails? In my case, I own a domain name that forwards all email to a Gmail account. I'm afraid that Gmail will one day go away, start charging, or lose my emails. It'd be nice to have the ability to search the emails that have been archived.
Thanks

Check the archive bit out. It may be what you want.
In .NET it's System.IO.FileAttributes.Archive, which can be used with SetAttr in VB, or System.IO.FileInfo.Attributes or System.IO.File.SetAttributes().
Any algorithm that checks the last modified time or archive bit will depend on the number of directories on the drive. Since both attributes are stored in the directory, the timing will depend on the filesystem and its level of caching. A more efficient way to analyse backup efficiency may be to look at the number of blocks that have changed.

I am looking at writing a program (.Net)for backing up files on a computer. How would I go on about knowing what files have changed to backup (I don't really want to scan the last modified dates each time.
Are there any backup algorithms for backing up only the bits of a file have changed. What are the O notations for the algorithm?

Take a look at django-chronograph. It has a pretty nice interface for scheduling jobs at all sorts of intervals. You might be able to borrow some ideas from that. It relies on python-dateutil, which you might also find useful for specifying repeating events.

+1 for django-chronograph, and it uses dateutil to provide a rich time specification language.

dateutil looks really powerful, but I don't think I'll use it for this project to keep the dependencies down. With the method described above I don't need anything more complicated than a bit of maths!

I am writing a backup system in Python, with a Django front-end. I have decided to implement the scheduling in a slightly strange way - the client will poll the server (every 10 minutes or so), for a list of backups that need doing. The server will only respond when the time to backup is reached. This is to keep the system platform independent - so that I don't rely on cronjobs or suchlike. Therefore the Django front-end (which exposes an XML-RPC API) has to store the schedule in a database, and interpret that schedule to decide if a client should start backing up or not.
At present, the schedule is stored using 3 fields: days, hours and minutes. These are comma-separated lists of integers, representing the days of the week (0-6), hours of the day (0-23) and minutes of the hour (0-59). To decide whether a client should start backing up or not is a horribly inefficient operation - Python must loop over all the days since a time 7-days in the past, then the hours, then the minutes. I have done some optimization to make sure it doesn't loop too much - but still!
This works relatively well, although the implementation is pretty ugly. The problem I have is how to display and interpret this information via the HTML form on the front-end. Currently I just have huge lists of multi-select fields, which obviously doesn't work well.
Can anyone suggest a different method for implementing the schedule that would be more efficient, and also easier to represent in an HTML form?

It's probably not quite what you're after, because I don't think what you're after is possible.
However you could place the tables in question into a different file group. Then when it comes to restoring, you need only restore the file group that relates to the tables.

is it possible to restore individual tables from a full backup file of Microsoft SQL Server 7 (yes, I know this is really old, but our client can't upgrade for various reasons).
The total backup file is about 180GB in size and restoring the whole database once a week to a development server is not pratical, as it takes several days (literally). But for development, we'd just need some tables out of this huge file.
Is it somehow possible to extract only the tables we need from the backup file?
Thanks in advance!
Best regards,
Martin

I admit this is not strictly a programming question, although I do use my WHS as a source repository server for home projects, and I'm guessing many other coders here do as well.
Does anyone have a recommendation for a good backup solution for the non-fileshare portion of Windows Home Server? All the WHS backups I've seen handle the fileshares, but none of the system files or other administrative stuff on the box.
Thanks,
Andy

Beginning with MariaDB 10.11 (and MariaDB Connector/C 3.3.8) the client side gssapi authentication plugin is now statically linked against the client library (which is used by all client tools)
There is one exception which is mariadb-backup - it doesn't use client library but the embedded server library (libmysqld), which is not linked against client gssapi plugin.
I filed an issue (MDEV-33192) in MariaDB Bug Tracker
Until this bug is fixed there are several workarounds:
Install auth_gssapi_client.dll from Connector/C <= 3.3.7 or from Server <= 10.10
Use another authentication method, e.g. native_password or ed25519.

installed MariaDB 10.11 on Windows. Try to do backup using
$ mariabackup --backup --target-dir=F:/backup --user=root --password=
https://mariadb.com/kb/en/full-backup-and-restore-with-mariabackup/
returns with
Failed to connect to MariaDB server: Authentication plugin 'auth_gssapi_client' cannot be loaded:
But on Mariadb web site it says this plugin is included with 10.11
Any ideas?
