How about using poundctl to disable and reenable the backend server? It must be run locally (the command protocol uses unix sockets), but you could probably have it launched remotely through an ssh session.
From the man page:
OPTIONS
[...]
-B/-b n m r
Enable/disable a back-end. A disabled back-end will not be passed requests to answer. Note however that existing sessions may still cause requests to be sent their way.
-n n m k
Remove a session from service m in listener n. The session key is k.

Our production environments typically consists in 4-8 Apache web servers and 2 (My)SQL servers :
Each web server is affiliated to one SQL server
SQL servers have a circular replication setup
All web servers are load balanced, by Pound for example.
Every night a job backups one of the SQL servers, locking the affiliated web servers for about 10-15 minutes.
Is there a way to configure the balancing to avoid reaching those locked servers for a short time?
Is there another way to handle this lock, other than backuping a non-production third server?
PS: We envisage to reload the Pound configuration, just before and after the backup, with an appropriate configuration file, but it feels a bit odd...

Really need help creating a script that backs up, and shoots out the error along the file that did not copy
Here is what I tried:
Creating lists of filepaths to pass on to copy-item, in hopes to later catch errors per file, and later log them:
by using $list2X I would be able to cycle through each file, but copy-item loses the Directory structure and shoots it all out to a single folder.
So for now I am using $list2 and later I do copy-item -recurse to copy the folders:
#create list to copy
$list = Get-ChildItem -path $source | Select-Object Fullname
$list2 = $list -replace ("}"),("")
$list2 = $list2 -replace ("@{Fullname=") , ("")
out-file -FilePath g:\backuplog\DirList.txt -InputObject $list2
#create list crosscheck later
$listX = Get-ChildItem -path $source -recurse | Select-Object Fullname
$list2X = $listX -replace ("}"),("")
$list2X = $list2X -replace ("@{Fullname=") , ("")
out-file -FilePath g:\backuplog\FileDirList.txt -InputObject $list2X
And here I would pass the list:
$error.clear()
Foreach($item in $list2){
Copy-Item -Path $item -Destination $destination -recurse -force -erroraction Continue
}
out-file -FilePath g:\backuplog\errorsBackup.txt -InputObject $error
Any help with this is greatly appreciated!!!

You should directly use that variable as SqlConnection requires a string object containing a connection string and you are storing it in a string object itself.
So it would be simply like this:
using (SqlConnection connection = new SqlConnection(strCon))
{
SqlCommand command = new SqlCommand(sSQL, connection);
connection.Open();
command.ExecuteNonQuery();
}
Recommended: (to store it in Web.config)
<connectionStrings>
<add name="job" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True" />
</connectionStrings>
Then access it like this: (using System.Configuration;)
ConfigurationManager.ConnectionStrings["job"].ConnectionString

You have used database keyword 2 times, so replace 2nd one with your database name. so finally it would be: BACKUP DATABASE @Your_db TO DISK = 'D:\\Database.bak';

On android you can use the java.util.zip (try Zipping with android) to zip your files and upload to the server and on IOS you can use the ZipFile class (look at this question for an example) to do exactly the same. Zip is a standard so it will work both ways.

Wordpress built-in export (WordPress eXtended RSS or WXR) would contain your posts, pages, comments, custom fields, categories, and tags. Images can be donloaded from the old location (must be live) to the new one; be sure to check the "Download and import file attachments" box on import.
If there are galleries managed/created by some plugin then you'd have to have a more detailed look at the particular plugin used.

The @{5 days ago} syntax relies on information from the reflog, as
explained in the section of the git-rev-parse documentation quoted below.
Reflogs are local to a repository, and never transferred by clone, fetch or
push. This is not the information displayed by git log, unless the -g or
--walk-reflogs option is used.
Bare repositories generally don't keep reflogs, so a copy of the repository
wouldn't have that information either.
<refname>@{<date>}, e.g. master@{yesterday}, HEAD@{5 minutes ago}
A ref followed by the suffix @ with a date specification enclosed in a brace pair
(e.g. {yesterday}, {1 month 2 weeks 3 days 1 hour 1 second ago} or {1979-02-26
18:30:00}) specifies the value of the ref at a prior point in time. This suffix may
only be used immediately following a ref name and the ref must have an existing log
($GIT_DIR/logs/<ref>). Note that this looks up the state of your local ref at a
given time; e.g., what was in your local master branch last week. If you want to
look at commits made during certain times, see --since and --until.

I'd like to try out a few things with git and I don't want to screw anything up in the working repository.
To try to keep things safe, I've made a copy of the bare repo that I work from and from this repo I am intending to do all my pushes and tagging. I used:
cp --preseve -r original.git copy_of_original.git
Although I understand one can undo bad commits and whatnot, I don't want to leave the repo with all these reverted commits, nor do I want to do any refactoring, hence my desire to just work from a duplicate, bare repository.
The problem is, I execute the following:
git diff --name-only master@{"5 day ago"} master
and get back:
warning: Log for 'master' only goes back to Fri, 15 Feb 2013 20:42:43 -0500.
The original repo, which I don't want to touch, does indeed have files which were modified as of 5 days ago.
If I perform git log on my copied repo, the record of these 5 day old changes are all still there.
What is going on here?
Is there a better way to make an independent copy of the repository?
Update 1
I realized I was imprecise with my question. I had run:
git diff --name-only master@{"5 day ago"}
in the directory produced from:
git clone copy_of_original.git clone_of_copy

Does copying the Git bare repo change the log?

I'm currently trying to move a single-server farm to an other server.
The old server is a windows 2003 32-bit with sql server 2005.
The new one is a windows 2008 32-bit with sql server 2008 r2 (32 bit).
Both MOSS 2007 have the same versions.
What I'm trying to do is to use a farm backup from the old server to restore it on the new one by using the restore tool on the central administration or by using the stsadm command, but it seems that it is not the best solution as the restore will fail.
In fact, what should I do on the new server ? Does it needs to exactly look like the old one ? Do I have to recreate all the web applications for instance ?
Is there any tutorial out there that could guide me step-by-step ?
Thank you for your help.

the .spl is only a lockfile - no there is no need to back it up.
I think the only option is to backup the data files as you note.
Note if you have RT indexes, then there might be other extensions (I think .ram). You should also backup the Binlog.
Although do see 'FLUSH RTINDEX' - that makes for cleaner backups.

Do like this:
Take full weekly backup with a unique name prefix like weeklybkp_
Then put a script like following in cron after every weekly backup.
DELETEMORETHAN=$(ls -1 weeklybkp* | wc -l)
if [ "$DELETEMORETHAN" -gt 4 ] ; then
COUNT=$(echo "$DELETEMORETHAN - 4" | bc -l)
rm -rvf $(ls -1t weeklybkp* | tail -${COUNT})

I have a CentOS server running with backup made to an external HDD.
I run a full backup everyday at 4am and incremental backups every 2 hour. I am keeping the last 30 days backups which is achieved by running a cron job every day at 6am which clears all files older than 30 days:
0 6 * * * root /bin/find /mnt/hp/backups -mtime +30 -exec rm -f {} \;
Recently my HDD is getting out of space so I am changing my backup strategy to only keep 4 full backups for last 4 weeks. Eg, full backup of the every Monday.
How do I write a script to keep last 4 full backup for the past 4 weeks? I am using dump to perform the backups

Rather than trying to script it yourself and test it, I would suggest using a commercial package (safer option since they have many customers and tested it under different conditions). One option would be to use software from Zmanda. They have a good solution for MySQL and support Amazon S3 so it should be fairly easy.

You need to (a) give the restored database a new logical name, and (b) you need to define new physical file names, so the existing ones won't be overwritten. Try something like this:
RESTORE DATABASE [Elmah_Restored] <== new (and unique) logical database name
FROM DISK = N'E:\Elmah_backup_2012_11_02_030003_1700702.bak'
WITH FILE = 1,
MOVE N'Elmah' TO
N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Elmah_restored.mdf', <== new (and unique) physical file name
MOVE N'Elmah_log' TO
N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Elmah_restored_log.ldf', <== new (and unique) physical file name
NOUNLOAD, STATS = 10

Marc_S, thank you for that information. What I am trying to accomplish is not restoring the backup under a different name, what I want is the backup process to fail instead of automatically overwriting the database. Essentially I want the if exists then fail semantics but I want the restore job itself to fail without me checking whether the database exists. Is there a no overwrite option?
– Chris Magnuson
Dec 6, 2012 at 19:59
@ObligatoryMoniker: the T-SQL RESTORE statement I have shown in my answer will NOT overwrite an existing database. For that to happen, you would need to add a REPLACE clause (e.g. after the NOUNLOAD)

I have a ELMAH database that I want to script the restore of using the following:
RESTORE DATABASE [Elmah]
FROM DISK = N'E:\Elmah_backup_2012_11_02_030003_1700702.bak'
WITH FILE = 1,
MOVE N'Elmah' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Elmah.mdf',
MOVE N'Elmah_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Elmah.ldf',
NOUNLOAD, STATS = 10
GO
Even though I am not including WITH REPLACE each time I execute this statement it restores over the existing database.
I will always drop all databases before this operation and I never want this code to accidentally restore a database over one in production.
How do I change this code so that it will never overwrite an existing database?
I am actually doing this through SMO objects but the principle and results are the same so I am hoping to keep this simplified to just the TSQL necessary in the hopes that I can generalize that information to what needs to be set on the appropriate SMO.Restore object.

Use mysqldump on the live server to get everything. It will create all the necc statements: drop tables, create database, etc. Call mysql with the resulting file (as a < pipe ) into the dev server (after clearing it out, if need be) to have it read everything in.
To keep the dev server in sync with the live, set it up as a replication slave.
In one line (for one DB):
mysqldump --opt db_name | mysql --host=remote_host -C db_name

I'm bringing the development server for a web application I work on back online. Currently it's extremely outdated (filesystem and database). Does anyway have a good/efficient way to do this?
Right now I am backing up the database from the live server so that I can import it into the development server, and then I am going to replace the files in the development filesystem with the live filesystem (most up to date).
This is the first time I will be doing something like this, and I DON'T want to mess up the database (well over 2GB in size). Can anyone give me some tips and recommendations?
Also, is there a way to have changes made to the live database sync back to the dev database, but without changes in the dev database being synced back to the live database?
Thank you!

I am using Altiris Deployment Solution 6.9 SP5. I want to create a back up image of Linux OS/CentOS. I have created the job using the following tasks:
Reboot to automation
Create Disk Image
Reboot
The jobs is stuck at step 2 as the machine goes on sleep immediately after reboot. It tries to send Wake-on-Lan signal but that doesn't work.
Is there a way to keep the system alive until the job completes successfully.
The machine am trying to take back up of is a B series blade server. I could not find any power setting in the BIOS settings to enable Wake-on-Lan.
Please correct me if the process listed above to create a back-up image in DS 6.9 is incorrect.
A quick help is appreciated. Thanks!!

Use GitHub or BitBucket. You have all the benefits of version control and a cloud storage for your repositories.
You can commit changes as often as you like, and only need traffic when you push or pull changes to or from the server. The version control systems are smart enough to sent only the modified files.
You could even have a team working on a local network, without the need of a cloud solution and only push to the cloud server periodically just for backup. To do that, you can create a script that pulls from your local repository and pushes to the server. That script can be run in a scheduler.
Apart from the service used to backup your files, I think you should use version control anyway. As a programmer I don't think you can live without.

I have a "Projects" folder which contains dozens of Visual Studio projects. I want to create a backup for them. First I thought I should copy them all to my SkyDrive or DropBox folders and let them be synced to the cloud whenever there is a change.
The other strategy would be using a source control but I don't want the backup to take place whenever a change is made and it should be optimized. By that I mean, only the changed files and only the changed parts should be uploaded to the server to save my bandwidth. I don't have a very good connection (512 Kbps).
Also my codes are very valuable for me so security is very important to me.
Is there a way to achieve the automatic backup to the cloud (ideally free) and take advantage of the source control options (such as revisions, etc.)?
I'm sure a lot of people have solutions for this and a lot of people have the same problem so please let the question be answered instead of just clicking "close"!

I'm not sure I have 100% understood what your problem is, and I don't know any function named BackupFile().
If what you want is reusing handles from NTCreateFile() with BackupRead(), it should be perfectly fine to do so, provided the file handle was opened with the right flags & permissions.
Be sure to call NTCreateFile with the FILE_OPEN_FOR_BACKUP_INTENT flag:
NtCreateFile(&handle, ..., FILE_OPEN_BY_FILE_ID|FILE_OPEN_FOR_BACKUP_INTENT, ....)
If you plan to pass the resulting handle to BackupRead().

I'd like to open up a file by ID and then use the resulting handle in the Win32 API BackupRead()
Is this possible? I'm not certain if its 'okay' to use handles that come from NtCreateFile() in other Win32 APIs?
For example, may I do this
NtCreateFile(&handle, ..., FILE_OPEN_BY_FILE_ID, ....)
BackupFile(handle, ....)
I'm somewhat bothered by using NtCreateFile, it's well documented on MSDN but they also mention compatibility problems could occur
Any ideas?

The below command is syntactically incorrect.
$command = "mysqldump --all -databases > mybkp/backup.sql ";
It should be
$command = "mysqldump -u myuser -p mypass --all-databases > mybkp/backup.sql ";
EDIT:
Added the -u and -p flag. Ensure that you post your MySQL user name after -u and MySQL password after -p

make a backup of the existing site if you are restoring over a current version (in case changes have been made)
Create any folders required and assign permissions
Create the User/Application pools if this is a new machine
Otherwise seems reasonable to me?

Can anyone recommend an efficient way of restoring asp.net sites, currently the steps I take are:
1) Unzip site backup
2) Edit web.config connection string to reflect my local SQLEXPRESS database
3) Restore Database in SQL studio 2008
4) Delete primary user in the database
5) Add the removed user in the Security tab and set him as the db owner
If anyone has any thoughts on reducing these steps or a different system any advice would be much appreciated.

It's simple enough. It works fine for a drive that is physically attached to my computer. However, I have a networked drive that I'd like to use for this task. I've tried a few things I found on forums, but to no avail. In the above code, I started attempting to use "net use." When I run it, I get "invalid drive specification" or "network path not found."
How can I get this to work?
Any help is appreciated.

MySQL binary log by definition is logging the data manipulations in binary form to save time and space for processing. So when you examine them, you should add --base64-output=decode-rows option to mysqlbinlog client have the the output decoded.

There are two main problems here.
First of all, change your set command into this: set hour=%time:~0,2% (hour without enclosing %-signs)
Next thing is, that times with a single digit hour value like 9:00 o'clock will be printed like:
" 9:00:00.00"
with a leading space in front of the first digit. This is the reason for your error message, as your file name might resolve to something like:
sageBackupLog-2012-09-11-hour 9.txt
This actually forms two parameters as the name is not enclosed with "
To overcome this and print a leading zero for these times, you can use a second set statement doing a string replacement, changing spaces to zeros:
set hour=%time:~0,2%
set hour=%hour: =0%
You can then safely use %hour% instead of set hour=%time:~0,2%0 in your script.
Hope that helps.
|
I have a script that does a simple XCOPY routine for backing up all our corporate files:
@echo off
IF %time:~0,2% GTR 7 (
IF %time:~0,2% LSS 21 (
XCOPY "R:\Sage Src" "S:\lastdata" /D /Y /E /R /K /C /H /I >> S:\sageBackupLog-%date:~-4,4%-%date:~-7,2%-%date:~-10,2%-hour%time:~0,2%.txt
XCOPY "R:\importantStuff" "V:\lastdata" /D /Y /E /R /K /C /H /I
EXIT /B 0
)
)
But ever since wrapping it all in the two IF statements, it no longer outputs the hour.
I have tried set %hour%=%time:~0,2% but it doesn't work, returning an invalid parameters error.

Yeah that's fine, just keep it to like once a day. We run wal-e for continus protection on everything. Also please know while you can figure out the API for pgbackpus easily enough, it is not public and subject to change at anytime. I've broken it on people who scripted in the past, not on purpose or vindictively, but to fix pressing problems. So just be aware that what you're doing is not really supported, but we're not going to get mad.
You might also want to look into just using straight pg_dump.

Following on from this earlier question, I've had a look at the Heroku client gem and written a Python script that performs Postgres backups on Heroku in the same way as the pgbackups addon.
Since the removal of the auto-month option on the free database tier I wanted a way to perform backups automatically via Heroku Scheduler.
However before I use this script I want to make absolutely sure it doesn't violate any Heroku terms, as that is the last thing I want to do.
The exact functionality of this script is as follows:
In the "show" mode, it sends a GET request to the PGBACKUPS_URL as defined in the environment, querying the /client/latest_backup endpoint for the details of the latest backup taken.
In the "capture" mode, it sends a POST request to the PGBACKUPS_URL, endpoint /client/transfers, supplying the DATABASE_URL from which the backup should be taken.
This is exactly how the native Heroku client performs pgbackups. The script is written in Python because I needed a Python resource for my Cedar stack projects, and would be run on the server via heroku run.
Please could someone "in the know" tell me if this is considered OK or not?
Many thanks.
|
Can someone from Heroku confirm my backup script doesn't violate their terms?
|
The best way is to use rsync, as you would be uploading (most likely) changes only.
http://linux.die.net/man/1/rsync
Additionally you can create incremental backup:
http://www.mikerubel.org/computers/rsync_snapshots/
So my suggested solution would be rsync + crontab

So I have a PHP application running on linux machine which is using a mysql database. I have manage to add the back up my mysql database every day by adding a code in the CRONTAB. In my application clients are able to upload document, of which a saved in a directory in the application folder ie /myapp/uploaded_documents/, I am looking at backing up this directory.
My question is: how do I back up a directory to a certain remote location on a certain time every day? Is it possible to also password protect this directory on my app folder?
Thank you

I have a standard iOS coredata application (sqlite). Users are requesting that they be able to backup and restore from backup their data. Can anybody tell me how to do so? Or some links where this is explained in detail? I don't mind using iTunes file sharing but would like to know how to implement this.
Also if the user restores a database if the database is not correct it should be rejected before replacing the existing database. I have searched the internet for this but did not find any examples.

You can copy files with Midnight Commander and then press skip button if you see that the file copy is stalled.
If you have just one file, it works perfectly. However, if there are too many files, it is hard to do manually. I wrote a bash script to deal with such situations.

This is a pure mysql commands solution which you could modify your code to do:
1.) CREATE TABLE new_table_name LIKE old_table_name
2.) INSERT INTO new_table_name SELECT * FROM old_table_name
Done. ;-)
This way you have an exact backup of your table previously, and joins are very easy to see the differences:
SELECT a.*, b.* FROM old_table a JOIN new_table b ON a.id=b.id WHERE <criteria>;
EDIT
UPDATE BACKUP SET COLUMN = (SELECT COLUMN FROM TABLE WHERE user_id=#) WHERE user_id=#;

I am working on a system which keeps track of what was in the field, prior to it being updated. I'd prefer using a table for the previous data, but am open to other options. This is some sample code which would accomplish the task :
<?php
$initial_value = $_POST['some_value'];
$id =231212213; // some id
$stmt = $mysqli->prepare("SELECT column FROM table WHERE user=?")
$stmt->bindParam("s", $id);
$stmt->execute();
$stmt->bind_result($column);
$stmt->fetch();
if ($column !="") {
//edit : it doesnt matter to me whether the data is moved into a new table or column
$stmtA = $mysqli->prepare("UPDATE another_table SET backup_column=? WHERE user=?");
$stmtA->bindParam("ss", $column, $id);
$stmtA->execute();
$stmtB = $mysqli->prepare("UPDATE table SET column=? WHERE user=?");
$stmtB->bindParam("ss", $initial_value, $id);
$stmtB->execute();
}
?>

Since the Express versions don't have the SQL Server Agent that executes jobs - no, I don't think this is possible.
What you could do however is create a standalone console app that uses the SMO library to perform the SQL Server backup, and then just schedule that console app on your machine using the built-in Windows scheduler, to runonce every day (or every four hours or whatever you need)
As for resources on SMO - check these out:

Have mysqldump create a local file, then use rsync with the --bwlimit option, or robocopy with the /IPG:n option to copy over the file to the network share:
@echo off
echo Running dump...
net use z: \\BackupComputerName\SharedFolder >c:\debuglog.txt 2>&1
cd C:\Program Files\MySQL\MySQL Server 5.5\bin
mysqldump.exe -uroot -pmypassword --result-file="%temp%\backup.sql" database_name
robocopy "%temp%\backup.sql" z:\ /IPG:100

Thanks very much for the quick answer. I haven't had a chance to test it out yet, but if it's copying the data over in small chunks, I'm hopeful that'll do the trick. I'll let you know what happens soon.

So it turns out the problem was actually a thread in my ASPX application that was chewing up a huge amount of CPU. Once I cleaned up that and a few other things, the dump worked fine with my original script. Still, it's likely I'll be using your solution in the future once my database gets larger, so thanks again for posting it.

I have a system I'm developing as follows:
-At any one time, three or four clients which are pumping data to the central server over a TCP socket.
-A Windows 7 Pro, 2.4ghz Dual-Core Xeon server with 4gb (soon to be 8gb) of RAM, which houses both an C# ASPX web application that receives the client data, as well as the MySQL database that the data is then put into.
-A mini-PC that stores the database backups, which are done every night. The batch file that I run, which works fine when there's no incoming TCP traffic, is:
@echo off
echo Running dump...
net use z: \\BackupComputerName\SharedFolder >c:\debuglog.txt 2>&1
cd C:\Program Files\MySQL\MySQL Server 5.5\bin
mysqldump.exe -uroot -pmypassword --result-file="z:\backup.sql" database_name
echo Done!
Right now, the database dumps are only about 5 megabytes. Even so, I notice that when the Xeon server carries them out while there's incoming TCP traffic, the client TCP sockets are significantly slowed down, if not disconnected entirely. And the database dump doesn't make it successfully to the backup machine. In fact, it started running in the Windows Task Manager at 8:20pm last night, and as of right now (12:21pm), it's still listed as running! (With no backup file generated yet.) I don't think that it's a coincidence that one of my clients died about a minute after the backup task was triggered last night.
Any ideas for how to reconfigure the backup routine and/or system configuration to make this work would be greatly appreciated.

Small MySQL database backup interrupts TCP traffic

Well, IF apache (or whichever webserver) on that IP is already configured for your FQDN (which you couldn't set to the new IP yet), then you could upload a PHP file with a phpinfo() call. Afterwards you could telnet onto the known IP port 80 and send
GET /[PHP-File] HTTP/1.1
Host: [Your FQDN]
So e.g., if your FQDN was www.example.com:
GET /info.php HTTP/1.1
Host: www.example.com
The web server should then send the output of your PHP script.
Note that your lines have to end with a <CR><LF> and that there is a blank line after your Host:-line.

I'm in the process of re-installing a backup of a PHP script on a new server.
The previous web developer has gone missing in action and he has yet to release the domain in that's under his management.
So for the new server they only provided me with mySQL details and FTP access. They say they don't have temporary testing url so I can only upload the backup without testing it.
I changed the mySQL server variables but in the script there are also some server side specifics. For example the full path has to be defined in the config file. I only have FTP access so I can't run a simple phpinfo().
Is there any other way to get this specific server information with only FTP access? I basically need the full server path where the script will be installed.
Thanks!

It suffices to read the documentation. It tells you exactly how to use wget or curl for use with a CRON job. Moreover, there is a section called "A PHP alternative to wget". I write the documentation of Akeeba Backup and make available free of charge for a good reason: to be read and prevent such questions ;)

Hey, unfortunately it does not work properly. When I execute the script "Sorry, the backup didn't work" is returned. I just copied the script from the documentation and changed the three parameters at the beginning of the script. The password is correct I checked it and also just called the URL via the browser and it seems to work there properly. Any ideas where I can look for an error description? I checked the log, but I found nothing there, but I can't say that I understood everything written in there.

we are using Akeeba Backup for backing up our Joomla website. It is possible to start a backup just by calling an URL as described here: https://www.akeebabackup.com/documentation/quick-start-guide/automating-the-backup.html. To automate the backup of our site we want to call this URL using a daily executed Cron job. Our web hoster supports the creation of Cron jobs, but you cannot use any shell scripts or something. Only the execution of a PHP script is supported. So we have to call this URL using a PHP script. I created this script and it works fine when calling it directly using my browser. But when I try to execute it using the Cron job I only receive error 302, which means, that the document has temporarily moved. I don't know what to do with that. This is the script I want to execute:
<?php
$result = file_get_contents("http://www.mysite.net/index.php?option=com_akeeba&view=backup&key=topsecret&format=r");
?>
I am not experienced with Cron jobs or PHP so any help would be nice.
Thanks for your time.

The command you show is a Linux / unix shell command. If you add another step
grep -v turnkey
you will omit any lines with the word "turnkey" in them.
Like so:
find /var/lib/mysql -mindepth 1 -maxdepth 1 -type d |
cut -d'/' -f5 |
grep -v ^mysql\$ |
grep -v turnkey
tr \\\r\\\n ,\ `
You didn't ask if this is a good idea. I don't think it is, because it relies on a particular ondisk structure for the MySQL server daemon software that is not part of the formal specification of the system. In other words, it could change.
You could do this:
SELECT SCHEMA_NAME FROM `information_schema`.`SCHEMATA`
WHERE SCHEMA_NAME NOT LIKE '%turnkey%'
ORDER BY SCHEMA_NAME
|
I am following the guide at this site and trying to exclude databases with the name turnkey in them.
find /var/lib/mysql -mindepth 1 -maxdepth 1 -type d | cut -d'/' -f5 | grep -v ^mysql\$ | tr \\\r\\\n ,\ `
this command returns all the database names, how can I remove the turnkey ones?

If you have mysql installed in your local setup, you can get a backup as just as the same way that you would take a backup of a database that resides in your local database server. For example, the following command would get you a backup of your database that you created under the RSS manager of StratosLive Data Service Server.
mysqldump -u your_username -pyour_password -h rss1.stratoslive.wso2.com extracted_host_name_from_the_JDBC_url_given_to_you database_name > local_file_system_path/backup.sql
Cheers,

I have created database on the Stratoes live server and my databse URL is this.
jdbc:mysql://rss1.stratoslive.wso2.com/karshamarkuptool_karsha_opensource_lk
I tried Database Console> Tools> Back Up and it asking me these credentials
Target file name:~/backup.zip Source directory:
jdbc:mysql://rss1.stratoslive.wso2.com/karshamarkuptool_karsha_opensource_lk
Source database name: karshamarkuptool_karsha_opensource_lk
Are my credentials right? it says there is no database found on the source directory.
If not what is the way to get a backup from Stratoes database? How can I configure it to get automatic weekly backup?

How to take database backup form WSO2 Stratoes Live Data Services Server

The way I solved this problem was:
Take monthly (or weekly/daily) backup, reset master so it restarts the log files. Pipe backup to the master so it refills the database one table at a time. Restart the slaves.
I had many more slaves and the table reloads didn't take too long. If your backup takes too long, you may want to do this a different way.
If you lose a slave, you can just have it restart through the log files as long as you start them with a table reload. If you backup from one of the slaves, it's critical to insure it's in sync with the master first.
There may be other ways to do this, but having a log file fresh start periodically became very useful.
Master Code to go in cron (This is from a way back, you should verify it works for you):
#!/usr/bin/ksh
date=`date +%y%m%d`
mysql -u root db_name -e "flush tables with read lock;"
mysqldump -u root -pYrPass --add-drop-table --add-locks natl_inv > /path/to/backup/db_name$date
mysql -u root -e "reset master;"
mysql -u root db_name -e "unlock tables;"
mysql -u root –pYrPass db_name < /path/to/backup/db_name$date
mysql -u root -e "flush logs;"
On the slaves:
use show slave status command to verify you are in sync with the master. If you want to resync to the master, run:
slave stop;
reset slave;
slave start;
You may need to stop mysql, delete the slave bin log files then restart and run the above.

I'm running MySql 5.1. I have Master and a Slave on 2 machines and I set up replication.
I do periodic backup on my slave server. I stop mysql, I copy all the files and I restart mysql.
In case I lose the Master, I can set up a new one from the last backup.
What If I lose the Slave? Can I restart the slave from the last backup? Am I supposed to keep track of the position of the replication every time I to a backup?

They're intentionally preventing users from restoring backups that are "foreign" to them in order to satisfy an obscure Microsoft security recommendation.
You will have to perform a schema comparison and a data comparison between your local machine and the empty database on the hosting to generate the scripts to re-create all of the objects and data. (Having those scripts available in a source control storage would also be helpful.)

Well, for one thing, it requires API Level 8 (Android 2.2) or greater, so currently about 6% of devices with Google Play can't use it. Otherwise, I think it's a safe assumption that the vast majority of devices with 2.2+ and Google Play have access to it.

Version control at the table level is usually done by adding a version column to your existing table. So if you had a posts table you would add a version column with a simple int or date value. Every time a post is edited a new record is inserted and the version number bumped. You can reference this version number in another table or have an additional active field to denote which post is the latest/active.
If you're talking about rolling back the database I would use the mysqldump command to dump and mysql to restore.

I've been working on a CMS and wanted to add a backup/restore function. I want it to backup a saved entry every other time it is edited so that if a client makes a change they are unhappy with or screws something up they can go back and choose a previous state to restore from.
The problem I'm having is trying to wrap my head around the concept of coding this functionality. I have created a new table called "backup" with the fields "ID, date, time, pageName, and pageContent" but going on from there I find myself stuck.
Would I add on to my edit script a new query that saves a duplicate to the backup table? And how could I get it to only backup every few saved edits?
Here I have my save edit query, if it helps any. Thanks in advance! :)
<?php
$_POST['entry'] = mysql_real_escape_string($_POST['entry']);
$sql="update pageEntry set entry=\"$_POST[entry]\", pageName=\"$_POST[pageName]\" where id=\"$_POST[id]\"";
$result=mysql_query($sql)or die('Bad Query');
echo "<div id='edit2'>The file has been uploaded, and your information has been added to the directory<br /></div>";
?>

Creating a PHP CMS with an entry backup/restore option

You need to have a LAMP stack installed on your local machine. In addition, you'll need to modify the settings.php file to change the database connection strings to match your local enviornment. Youi may also need to modify the $base_url variable in the settings.php.
THis would not be necessary if you were simply restoring, but since you're moving the install it is required.

So I wrote this script that basically creates a sql dump of the the drupal databases as well as created a tar of of the www directory. I took this off the server and put it on my local machine. I want to take these backup files and test to see if the backup is stable as well as to learn the process.
My problem is that I can't find any clear instructions on how I would be able to do this. Can anyone give me a hand?
Any help is much appreciated.

Reverting is fairly simple create a new database and call it another name so say your current db is magento1 create magento2 with your backedup data, and make sure your current magento db user has rights to the new database.
Now edit app/etc/local.xml change <dbname><![CDATA[magento1]]></dbname> to <dbname><![CDATA[magento2]]></dbname>, clear all caches and your site should now be pointing at the old data.
This is a quick fix method, but it seems like that is what you are looking for right now.

My magento site which was working fine before an hour now giving error as I have imported
customer data from csv file with REPLACE Esisting Complex Data mode as we want to update some of our customer data.
but when I tried to add product into the cart from frontend with existing customer it gives me error as-:
Item (Model_Customer_Customer) with the same id "11" already exist
exception 'Exception' with message 'Item with the same id "11" already exist' in /htdocs/localhost/magento/lib/Varien/Data/Collection.php:373
Can somebody guide me what should I do now??
Or tell me how can I revert back to original database as I take backup of database daily.
So I have yesterday's backup of database of my site.
So how can I revert back to yesterday's database?
plz plz help me....

Magento Import Customer Error...Now Applicatiion itself not running?

From the databases viewpoint we are dealing with an unclean shutdown (i.e. power went off) and a lost connection so it will discard all transactions that are not committed.
If you are taking a snapshot of the server that's just like freezing everything in a cryogenic sleep, then after a restore the database would just awake expecting to talk to a non existing application.
The only issue that i can see is not from a transaction itself but from the fact that the database itself resides inside files. What if you freeze a file half-written to disk. I can see how that might be a problem. On the other hand there's probably some architectural design in place to prevent this as the same is true for a power outage and a database should live through that too.
|
Let's say your taking daily snapshots of your server as a whole (public_html, sql files, etc) for later restoration in case of system failure.
Is it possible that you can restore damaged a MySQL InnoDB if you took the snapshot while an uncommitted transaction was taking place? Or will InnoDB do just fine and discard "incomplete" transactions on restoration?

Can server snapshots potentially damage MySQL transactions?

I have a directory structure as follows
Client_Site/
some_folder1/
some_folder2/
some_folder3/
Lots of files
some_folder4/
Client_Site2/
and so on. I want to target the some_folder3 within the directory structure of each client site and only backup that folder with rsync, but maintain the rest of the directory structure as empty folders.
Is this possible? What would my include file look like?

I've got a writing and reading database application holding a local cache. In case of an application server fault a backup server shall start working.
The primary and backup application can only run exclusively because of its local cache and some low isolation level on the database.
As far as my communication knowledge goes it is impossible to let both servers always figure out who is allowed to run exclusively.
Can I somehow solve this communication conflict through using the database as a third entity? I think this is a quite typical problem and there might not be a 100% safe method, but I would be happy to know how other people recommend to solve such issues? Or if there is some best practice to this.
It's okay if both application are not working for 30 minutes or so, but there is not enough time to get people out of bed and let them figure out what the problem is.

There is no way to get the exact backup size until you try backing up the database.
Approximate size can be guessed at by looking at database file sizes. This is useful if you have no idea how big it will be and you need to "publish" some estimate to the unfortunate user whose disk is full. But the real database sizes will likely be much smaller.
SELECT CAST(SUM(size) AS DECIMAL) * 8192 from sys.database_files
Given that you will have to add that try-catch clause anyway, much easier and more accurate estimates can be obtained from looking at the last backup size like this:
SELECT TOP 1 database_name, backup_size FROM msdb..backupset ORDER BY backup_finish_date DESC
You can compare either of these values to the amount of free disk space. It may be useful to add some margin to the number obtained by the latter method to account for some expected gradual database growth.

We want to take db backups programmatically. For this we used the SqlServer.Management.Smo namespace and its classes, and it is working perfectly.
Now we have a requirement to determine whether there is enough space is there in the location to hold the backup files before saving the db backup to the specified location.
And if there is not enough space, we want to alert the user of that fact.
One way we found is that put a try catch and catch the exception if there is no enough space in memory. But we are looking for a solution to get the size before saving it.

Make a regular dump with MySQL dump or use another specific database back-up tool. A copy of the data folder is not ok.
MySQL dump will really read the data and can be checked. It is not always true that all data is written completely to the data file and lockings give issues.
If you have a specific time of back-up just run a cron before that moment and verify whether it is safe and finished. MySQL will take care of lockings, changes, transactions etc.
Always, read always, verify your back-up with a restore test.

not sure its a stack overflow question
I have a Mac and am hosting a Apache MySQL server on it using MAMP Pro. If I back up my data on the time machine, is MySQL database also backed up or do I have to create mysqldump and backup up as a cron job? In case of a crash do I do a normal restore in case it can be backed up on time machine.
Thanks

I am not aware about such a "mixed" storage mode for the hadoop. So I do not think that your scenario is directly supported by hadoop.
For me it looks like you need more "elastic" solution. If EMR would be available open source - it might be good choice - where NAS would play the role of S3.
I would suggest the following solution in Your case:
Install and run data nodes on all available servers. They are not as resource hungy as task trackers - since they are only sequentially read/write data.
Install task trackers on all machines also, but run only on these which are not used now. Hadoop is smart enough to preserve data locality when possible. In the same time hadoop will takes change in number of task trackers much easier then disappearing data nodes.
Alternatively you can build cluster of task trackers only, not use HDFS and run jobs against the NAS.
In all cases the main interference with other users I still expect is network congestions - during shuffle stage hadoop is usually saturating the network.

I have Hadoop running on a cluster that has non-dedicated nodes (i.e. it shares nodes with other applications/users). When the other users are using a cluster's node, it is not allowed to run Hadoop jobs in that node. Thus, it is possible that only a few nodes are available in a given moment, and that this few nodes do not have all data blocks (replicas) need by the Hadoop job.
I also have a big Network-Attached Storage that is used for backup. So, I am wondering if there is a way to use it as a secondary storage for Hadoop. For example, if some data block is missing in the cluster, Hadoop would get the block from the secondary/backup storage.
Any ideas?
Thanks in advance!

of course can duplicity verify existing backups. it just does not do this as it assumes that you are sensitive about traffic costs (s3 etc.).
simply do as described in
P.S. I have found this, but it is used to see "what files, if any, have changed since the last backup" and not to verify the integrity and consistency of a backup file.
before the backup and conditionally start a full if that fails. be aware that the completre backup chain has to be downloaded for this so it will nearly double your traffic.

I have heard that Duplicity is a nice tool for doing incremental backups.
The only thing I am concerned with is verification.
How does Duplicity check the backup for being consistent before it syncs it to a server? Does it actually do this?
It would not be nice to find oneself facing a corrupted backup file issue when trying to restore a backup.
As I understand, the basic workflow of Duplicity is the following:
Generate a delta from a directory which has to be backed up;
Sync this delta to a remote storage.
Is there any verification of this delta between 1 and 2?

You have the flexibility to do a few different things here, but I think starting your repo at the root / and tracking your files recursively is the way to go. Git will pick up the files in your subfolders.
The key advantage to this is that you basically have snapshots of your entire app, and can easily checkout the repository when creating a development or staging environment.
Git is great for managing the code changes, but I'd still suggest using something like rsync to backup the entire site every once in a while. That way, you can only track files that are going to change consistently (code, user generated content, etc) instead of backing up images/audio/other that are NOT going to be changed. Better to be safe than sorry :)

I have a website with multiple folders that have different purposes on the site. Think
/
/forum
/drupal_site
/contact
/about_us
Now how should I handle backups for these? Should each folder have its own repository? Should there be one for the entire site? Is Git the way to go in the first place?
Does it not make a difference and is up to whatever is more convenient to me?
Is there any "standard" way to do this or each person does it differently?
Also should each of those folders have their own js css and img folders or should that be shared across the site (only in the root)?

In your service you can loop through the list of files, find the ones that are x number of days old and delete them.

In my opinion using a version controll system is not overkill at all. You can keep hand on changes all the time. Making features that you don't even know whether to include or not into main branch. Not only features but every complicated task also, for example refactoring. With VCS that's no problem to make fast fix to released product during development of a huge task which is incomplete.
I can't imagine working without any VCS. I prefer Git because is fast and easy.

My app is getting to the point where I will be highly perturbed if I lose the source somehow. This is a personal / single developer project, so something like Subversion might be overkill. I'm thinking more along the lines of the "Backup" agent that is a part of the GExperts add-on in the Delphi world. Is there such a thing (that would backup all the .java, .xml, sqlite, etc. files) specifically for or suitable for the Android platform?

A quick peak on the command line shows these are deprecated commands.
mysql> help backup; Name: 'BACKUP TABLE' Description: Syntax: BACKUP TABLE tbl_name [, tbl_name] ... TO '/path/to/backup/directory'
*Note*: This statement is deprecated and is removed in MySQL 5.5. As an alternative, mysqldump or mysqlhotcopy can be used instead.
I'd say any advice on how to use deprecated commands is a bit of a misnomer. Take a peak at mysqldump. There are other options as well such as LVM snapshots etc.

I understand that I can use MySql's command BACKUP and RESTORE to backup a database and rollback when needed.
My question is, would I be able to execute it this way:
sql="BACKUP my_db TO DISK my_backup_folder WITH FORMAT #";
if ($stmt = $this->connect->prepare($sql)) {
$stmt->execute();
$stmt->close();
} else {
$error = true;
$message['error'] = true;
$message['message'] = CANNOT_PREPARE_DATABASE_CONNECTION_MESSAGE;
return json_encode($message);
}
And the restoration made in the same fashion:
sql="RESTORE DATABASE my_db FROM DISK my_backup_folder WITH FILE #";
if ($stmt = $this->connect->prepare($sql)) {
$stmt->execute();
$stmt->close();
} else {
$error = true;
$message['error'] = true;
$message['message'] = CANNOT_PREPARE_DATABASE_CONNECTION_MESSAGE;
return json_encode($message);
}
And in each case what does # stand for, is that .bak ? And is there anything else I should add besides what's in there ?

These are my settings from app.yaml:
builtins:
- remote_api: on
- datastore_admin: on
- appstats: on
- admin_redirect: on
- deferred: on
What am I doing wrong? It works for one app and not the other. I have not enabled federated login so it should work.

The purpose of a database dump, or of any backup data, is to provide a snapshot of what the database looked like at a particular point in time so that if something catastrophic happens you can revert to that version of a database. If you make changes to the database and want a more up-to-date dump that reflects those changes, the solution is not to modify a dump you already created; rather, it is to make a new dump from the database. When you are satisfied, you can then delete the older dump if space constraints are acute.

And I want to update that same file every week with the new data that expires and retaining the old archived records. I know there are some other way to do this with a more legit backup solution, but sadly I dont have much room here to play around with server configuration and such. Best thing I can do some corn jobs.

I would like to encrypt a file with most secure algorithm that also meets the following requirement.
Let's say we have a text file that has 100 Bytes and we encrypt it.
Now we change 1 byte in original file and encrypt again.
If we make a diff of the encrypted files then ideal encryption algorithm should produce the shortest diff possible - e.g. 1 byte.
(Essentially I want to do a incremental backup of encrypted files and minimize bandwidth requirements)

You could use Amazon AWS .Net SDK. You can download it from here:

function DownloadS3File([string]$bucket, [string]$file, [string]$localFile)
{
if (Test-Path "C:\Program Files (x86)")
{
Add-Type -Path "C:\Program Files (x86)\AWS SDK for .NET\bin\AWSSDK.dll"
}
else
{
Add-Type -Path "C:\Program Files\AWS SDK for .NET\bin\AWSSDK.dll"
}
$secretKeyID= $env:AWS_ACCESS_KEY_ID
$secretAccessKeyID= $env:AWS_SECRET_ACCESS_KEY
$client=[Amazon.AWSClientFactory]::CreateAmazonS3Client($secretKeyID,$secretAccessKeyID)
$request = New-Object -TypeName Amazon.S3.Model.GetObjectRequest
$request.BucketName = $bucket
$request.Key = $file
$response = $client.GetObject($request)
$writer = new-object System.IO.FileStream ($localFile ,[system.IO.filemode]::Create)
[byte[]]$buffer = new-object byte[] 4096
[int]$total = [int]$count = 0
do
{
$count = $response.ResponseStream.Read($buffer, 0, $buffer.Length)
$writer.Write($buffer, 0, $count)
}
while ($count -gt 0)
$response.ResponseStream.Close()
$writer.Close()
echo "File downloaded: $localFile"
}

That's cool and all but I am trying to figure out how to do this using the Cloudberry Powershell cmdlet. This is a powershell and SQL Agent problem.

I am trying to automate my SQL database backup process. My goal is to use the Cloudberry Powershell cmdlet to give me direct control and access over my S3 buckets. I am able to do this manually but cannot get my SQL jobs to work with this.
According to Cloudberry's installation instructions, I shouldn't have to register the Cloudberry Powershell snap-in if Powershell is already installed. I have found that to be false. I have tried to register it, both 64-bit and 32-bit with no luck.
This works when executed manually/explicitly from the ISE:
Add-PSSnapin CloudBerryLab.Explorer.PSSnapIn
$today = Get-Date -format "yyyy.MM.dd.HH.mm.ss"
$key = "mykeygoeshere"
$secret = "mysecretgoeshere"
$s3 = Get-CloudS3Connection -Key $key -Secret $secret
$destination = $s3 | Select-CloudFolder -path "ProductionBackups/MyClient/log/" | Add-CloudFolder $today
$src = Get-CloudFilesystemConnection | Select-CloudFolder "X:\backups\MyClient\current\"
$src | Copy-CloudItem $destination -filter "log.trn"
^ When this command is executed in a SQL Agent job, it fails with this message:
Executed as user: DB-MAIN\SYSTEM. A job step received an error at line 1 in a PowerShell script. The corresponding line is 'Add-PSSnapin CloudBerryLab.Explorer.PSSnapIn'. Correct the script and reschedule the job. The error information returned by PowerShell is: 'The term 'Add-PSSnapin' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. '. Process Exit Code -1. The step failed.
I read in this blog post that SQLPS.exe cannot execute 'Add-PSSnapin' commands? Is that true? I cannot find any clarification on the subject...
how can I automate my SQL backup files to the Amazon S3 cloud? I have tried everything. TNT Drive was a huge waste of time. I am hoping Cloudberry can do it, any tips?

select INTO mycomputer\SQLEXPRESS\target_table from ReMOTECOMPUTER\SQLEXPRESS\source_table
or anything similar? Can I do that, what is the proper syntax if yes. I tried but was not successful.

copying data between servers on two different machines - SQL

I've successfully used Amazon's S3 to store the "output" data of web and non-web applications. Using a service like that is beneficial from the single-point-of-failure perspective because then any other instance of that web application, or a different type of client, on the same server or in a completely different datacenter still has access to the same output files. Another similar option is Rackspace's CloudFiles.
Both of these services are very redundant, and you could use them as the back, and keep the primary storage on your server, or use them as the primary and keep a backup on your other web server. There are lots of options! Hops this info helps.

I am making a DR plan for a web application which is hosted on a production web server. Now that web server also acts as a file storage for storing the feed uploads files (used by the web application as input) and report files( output of web application processing). Now if the web server goes down , the files data is also lost, so need to design a solution and give recomendations which eliminates this single point of failiure.
I have thought of some recommendations as follows-
1) Use a seperate file server however it requires a new resources
2) Attach a data volume mounted on the web server which is mapped to some network filer ( network storage) which can be used to store the feeds and reports. In case the web server goes down , the network filer can be mounted and attached to the contingency web server.
3) There is one more web server which is load balanced however that is not currently being used as file storage , and if we can implement a feature which takes the back up of the file data regularly to that load balanced second web server , we can start using that incase the first web server goes down. The back up can be done through a back up script, or seperate windows service , or some scheduling job for scheduling the backup job every night.
Please help me to review above or suggest new recommendations to help eliminate this single point of failiure problem on the web server. It would be highly appreciated?
Regards
Kapil

Mysqldump is a simple and reliable way to do backups.
Explore the documentation:
http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
If you want to copy your dumps on another server, you can write a bash script that copies dumps over ssh.
Here are some links that may help you:

I need to find a good backup solution for the site I have hosted with HostGator. HostGator only backs up sites with less than X number of files. Unfortunately I've exceeded that limit and they aren't backing up my site any more.
This means that right now i have no database backups. I do have backups of all the files on my computer, which I'm good with. But I need to find a solution that backs up my databases with no manual maintenance. HostGator doesn't offer additional backup services.
My site has cPanel access.
Any suggestions for solutions?

xcopy provides methods for copying files based on their Archive attribute. The option you would likely want is /M, which copies only files with the Archive attribute set, and resets that attribute. It kind of relies upon the Archive attribute being set, but Windows does this by default (I think) when creating or modifying a file.
For example (a rubbish example, but an example nonetheless):
C:\tmp>echo hello > out.txt
C:\tmp>xcopy /M *.* ..
C:out.txt
1 File(s) copied
C:\tmp>xcopy /M *.* ..
0 File(s) copied
C:\tmp>echo hello > out2.txt
C:\tmp>xcopy /M *.* ..
C:out2.txt
1 File(s) copied
Only files that are new/modified since the last copy are copied.
Alternatively, depending on your Windows version, you could look into the much more powerful (and hence more confusing) robocopy.

I have an Oracle archives folder on windows, which I need to take an incremental backup everyday at 6:00AM.
I need to copy all the files generated during the previous day, and place them in a folder with today's date.
What is needed is that, the files generated after the last backup was taken, only should be copied [i.e, the file names with the sequence after yesterday's backup's last file].
I tried xcopy, but it doesn't provide any facility for copying files based on modified time.
I need to write a batch script for this, please help me out!

How about something like this :
set fromField to text 7 thru -1 of (do shell script "cat /test.eml | grep From:")
set dateField to text 7 thru -1 of (do shell script "cat test.eml | grep Date:")
set toField to text 5 thru -1 of (do shell script "cat /test.eml | grep To:")
set subjectField to text 10 thru -1 of (do shell script "cat /test.eml | grep Subject:")
The body is a little harder since you need to decide if you only want the emails body or also all the previous emails that are embedded into the body. The following gets the body of my test email.
set temp to do shell script "cat /test.eml"
set text item delimiters to "--"
set temp2 to (text item 3 of temp)
set text item delimiters to "
"
set messageField to paragraphs 6 thru -1 of temp2 as text
Make sure you watch out for the encoding of the file if you use other characters.

Library/WebKit is included in the backup. With the exception of Library/Caches, everything in the Library directory is backed up.
The data included in an iCloud backup for your app is identical to that included in an iTunes backup, so you can examine the contents by backing up to iTunes and using a tool like iPhone Backup Extractor to see what's included.

I have a phonegap iOS app using the sqlite DB of Webkit (through UIWebView), and I wonder if the sqlite data will be saved with iCloud Backup (iOS5). The sqlite data are stored in Library/WebKit folder. In the apple doc, they say:
The placement of files in your application’s home directory determines what gets backed up and what does not. Anything that would be backed up to a user’s computer is also backed up wirelessly to iCloud. Thus, everything in the Documents directory and most (but not all) of your application’s Library directory.
But it can say exactly which folder in the library directory are not saved. And I don't know how to access iCloud to check if the directory is saved

Is iOS 5 iCloud Backup save webkit data for app using the storage of a UIWebView?

No, that does not appear to be a feature included in the PG Backups addon provided by Heroku: http://devcenter.heroku.com/articles/pgbackups#restoring_from_a_backup

Why didn't you write this question in the library forum?
OK, here is some sample code:
function SaveFolderToBigTableFile(const aFolder, aFile: TFileName): boolean;
var SR: TSearchRec;
BT: TSynBigTableString;
aPath: TFileName;
Path: RawUTF8;
begin
DeleteFile(aFile);
result := true;
BT := TSynBigTableString.Create(aFile);
try
aPath := ExtractFilePath(aFolder);
Path := StringToUTF8(aPath);
if FindFirst(aPath+'*.*',faAnyFile,SR)=0 then
try
repeat
if (SR.Name[1]='.') or (faDirectory and SR.Attr<>0) then
Continue;
if BT.Add(StringFromFile(aPath+SR.Name),StringToUTF8(SR.Name))<>0 then
writeln(SR.Name,' added') else begin
result := false;
writeln(SR.Name,' ERROR');
end;
if BT.CurrentInMemoryDataSize>100000000 then
BT.UpdateToFile;
until FindNext(SR)<>0;
finally
FindClose(SR);
end;
finally
BT.Free;
end;
end;
The trick is to use a TSynBigTableString class using the file name as key.
You can add very fast compression just by using our SynLZ library (much faster than zip, but of course with a bit less compression ratio).

I think you should:
Create file which will store you login/password and set minimal permissions on it.
Create bash script/php/perl script which will run mysqldump command and read settings from this file.
Set this script to cron.
But if you run cron under root so you can specify user/password directly in cron because onlyrestricted number of users can look through this file.
|
I want to schedule a cron job that either uses mysqldump directly, or calls a script that does the mysqldump. My question is since mysqldump requires a password to be supplied, is it secure to do mysqldump directly as a cron job? If not, while using a script, what's the most secure way of protecting the password?

I figured it would be easy to just insert a new row in some sort of history table using PHP, (containing date, table, column, value etc) on each UPDATE operation, but having MySQL do that automatically in some way would be way more efficient.
Also, the restoring part could be simply a (quite unefficient) PHP script, unless it could be done with a single query (not sure how)
Thanks in advance

Well, if we change "maintaining the most recent copy" by "copying only the modified files", then this command do that:

I am trying to create a batch file that will allow me to copy files that are scattered across several directories into a single location while maintaining the most recent copy available.
This is for a Windows machine.
For example...
C:\Base Files\*.jpg
C:\Base Files\Sub\*.jpg
C:\Base Files\Sub2\*.jpg
and copy all of these to C:\Backup.
I am trying to do something like the following...
FORFILES /p "C:\Base Files\DIR01\My Images" /s /M *.JPG /c "copy @file C:\SANDBOX\DIR02"
But it dumps out each time right away with a "File not found" message.
Thanks in advance for your help!

Copyfiles from Directory Tree to Flat Folder - Keep most Recent

The backup process started working after I checked in a file that had been checked out by a user on my client's production server.
I found out what file that was by opening the corrupted backup file and looking at the title of the last entry.
|
I got a backup of a Sharepoint 2010 site that I created from our client's production server so that I can make some new changes to it on my staging server.
I can restore the site collection from the backup without a problem but when I try to create a backup of the same site on my staging server, I always get the error "Operation is not valid due to the current state of the object".
Before the error is given however, a small part of the backup file is created. If I try to run the Backup-SPSite again, it always fails at the same point and the corrupt backup files are always the same size.
Going through the logs it looks like the problem might be related to user permissions. I wonder if it's possible that the user permissions, user data, etc that came over from the client's production server are somehow screwing the backup process now because the same data cannot be found on my staging server.
The same error is mentioned here http://technet.microsoft.com/en-us/library/ee748617.aspx but UseSqlSnapshot parameter doesn't work anyway in my case.
I've been hitting my head against the wall with this problem and would appreciate if anyone has any advice on what might help! :)
The setup:
Windows Server 2008 R2
Sharepoint 2010 Server (no SP1 because it hasn't been installed on the client's production server)
Microsoft SQL Server Express Edition
Cheers!

Enabled iTunes file sharing in your app's settings and then write your file to the Documents folder in your app. This will then allow them to see the file through iTunes.

I want to implement a backup feature in the app I'm working on, that simply puts an image and some data in a folder that can be accessed through itunes or similar.
But is this possible, and what can be done?
Point of the feature is that if (for some reason) the image and data isn't sent to my server, the user will have the ability to extract it to a pc/mac, so that the image and data isn't lost.
Any help is appreciated.

In your case, Amaxon's S3 seems more fitting but that's not free.
Depending on your target audience, you can create a local archive and have that picked up by your regular backup solution. You might try Wuala,or SpiderOak. Expand Wuala by adding your own space. Spideroak is free up to 2GB (more if you invite friends), and also provides a good alternative to Dropbox (if you want to see how to migrate from dropbox to spideroak see my blogpost about that).

I made a small backup application that simply creates an archive out specified files and folders. Now I need an online service to backup that online. Which service can i use that can be integrated into my app ?
Options I considered:
dropbox is ideal, but they have all but abandoned the desktop.
skydrive has no api.
I couldn't find any free reliable backup service that uses ftp .
anything else ? it should provide 1-2 gb of free space and be reasonably reliable.
Thanks
My app is in C#, but can be ported to any other language as well..

Your description makes it sound like you want to control your revisions. Use a Revision Control System like SVN or Git (http://en.wikipedia.org/wiki/Git_%28software%29).
At a high level, once you make changes to your code, you check those changes in and get a revision number that specifically identifies the most current state of the files at that time (e.g. revision 17). You could then switch to your production server and update the set of files to revision 17 and then compile/whatever. If all does not go as planned, it is easy to revert to any previous version (say revision 15, which was on the production server before you checked out and built revision 17).
A good RCS will manage all your files so that they are "backed up" and can you can restore the code/binaries/config files/whatever you had at any given time by referring to its revision number.

Lets say I am updating an application and have updated 10 files out of a 100. I made these changes on my test machine and is working but now I want to commit these changes to the production machine. What kind of option do I have.
Ideal scenarios would be.
I save the existing files that I am replacing
I copy new files over the old.
If the changes does not go well, I can reverse the process and restore the old files. What is the best way of doing it. Lets say I am talking about an ASP.NET application. I will also be updating SQL statements, but I can take core of that in separate SQL Script and not worried about that in this update.
I am familiar with Batch scripting but is there a better way of doing it, which has a GUI (Ok I can can create a GUI application and run the batch file from GUI).
Any one who has done something similar?

Well, as ImpEx does not support it, you may install another forum software (phpbb, smf, ipb), import your data to this installation using their tools which likely support importing from vb4, and after that import content from this installation to your new vbulletin 4 installation using impex.
There are some disadvantages however:
You may have to re-set your permissions because of the differences in permission systems in different software.
Your user's passwords will become invalid and they will have to recover them via email. This, however, might be considered as a plus because your db was compromised, password hashes and salts could have leaked and knowing this it isn't very hard to bruteforce someone's password on modern hardware.

I have a vBulletin installation that was recently defaced as a result of a sql injection flaw in the VB search interface. I'd like to move all of the posts/threads/permissions/users from the old database to a new database in which I just freshly installed vBulletin. Their impex program won't help with this, as it seems to only be able to import data from old versions of vBulletin, not from one vBulletin 4.x database to another. Does anyone know how this can be accomplished?

How do you move users/posts/settings from one vBulletin installation to another?

My gut instinct tells me this is not a good idea. It might be a better plan to save a link to where the VS 2008 back up is on Sharepoint, but adding a huge load of data to any sort of storage device is always going to be a bit fraught.
For example, whilst you can save images and files into SQL Server directly, most people prefer to save the files separately, and store the retrieval path in the database.

No idea why the incorrect one worked in debug but not release.

I have a small c# wpf app for doing some simple calculations running off a Sql Express 2008 R2 db, and in the setup section is a backup button that runs the code
using (DTZDataContext db = new DTZDataContext())
{
db.ExecuteCommand(string.Format("BACKUP DATABASE DtzDb TO DISK = '{0}'", filename));
}
The connection string I am using is
Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\App_Data\DTZ.mdf;Integrated Security=True;User Instance=True;Database=DtzDb
I have confirmed there are no other open db connections at this point in the application and the backup runs fine in debug, but once I compile for release (running from VS or as standalone) I get the error:
Operating system error 32 “32(failed to retrieve text for this error Reason 15105)” BACKUP DATABASE is terminating abnormally.
How can I fix this, preferably without having to install Sql Management Studio on each machine and attaching the DB? What is the recommended way of doing backups? Why does it work in Debug but not Release.
Many Thanks

I am completely lost here and I am running out of time. Let me explain my situation:
I have created a software in C# express 2010 and SQL Server Express 2008 R2.
Now in the settings section of my software, the user is supposed to be able to make manual back ups/restores of the database.
Also he is supposed to be able to schedule back ups of the database, which will run at time that he will set.
I do not have a clue on how to get both of these working and I am hoping that someone here may point me in the correct direction.
I need to be able to create a
backup/restore of the database from
the click of a button
I need to be able to schedule backup

Please keep in mind that when the user will install the software on his computer, he will not have sql server installed (I am saying this because I am under the impression that SMO requires sql server to be pre installed on the client machine).
Thank you

c# express back up/restore database

Those things like logins are stored in SQL Server master tables - they are not part of your backup of abcDB.
Users on the other hand are part of your database, so they get backed up together with your data.
So when you restore your database on another computer, your database will contain the users, but if they depend on a login, that login might be missing from that SQL Server's master database (and will need to be re-created, e.g. as part of your installation)

i am using sql server express and visual studio on my office PC.
i have a database abcDB. i created a login abclogin with password = 'abcpass' , default database =abcDB ,
now a winform application, is allowed access to abcDB when correct id and password is supplied via textbox.
if i want to use the same application on my home pc, then what tasks would i have to perform :
create an .exe of my application
install the application from its .exe on my home pc
install sql server on my home pc (do i have to install the same version as on my office pc)
i would not install sql server management studio, as i only have to use the application and not to play with the database which i do on my office pc)
start using the application
but what about the database. i would backup it and restore on my home pc. will this also take the backup of the 'abclogin'? or will i have to create it again from sqlcmd or installing management studio on my home pc .
when i created abclogin default database =abcDB ,then did it store this detail in the abcDB.mdf file or it is stored somewhere else?

Perl Backup Script Advice and Examples Please
|
You wouldn't be able to monitor something like that - you're exec()ing an external program from PHP, so PHP is suspended while that external process is active. As well, tar can't report in advance how much there is to do, it can only report on what it's done or is currently doing.
A progress bar works on the basis of (how much is done / how much there is todo) * 100. Without knowing in advance exactly how many files/bytes there are to back up with tar, you can't calculate a completion percentage.
|
I know this is a rookie question but whats actually happening with a progress bar what is it actually monitoring.
I figure the only way to understand it is to get this answer.
when i run a piece off php code how can i get a progress bar to monitor it while it runs untill completion off the code??
most progressbars i have seen are file upload and download. is it monitoring the amount off requests the browser sends when upload the file so its monitoring the bytes that are being transfer?
Can someone please give me a better understanding off whats going on?
I just want a simple progress bar to monitor progress while my php code is running so say if i am running this simple code to backup a websites files and folders, how could i do this???
<?php if ( isset($_POST['backup']) ) {
if(exec("cd {$_SERVER['DOCUMENT_ROOT']}/wp-content/plugins/s3bk/files;tar -cvpzf backup.tar ".get_option( 'isd-server')."")) { echo "done"; }
}
<form id="backup" method='post' action=''>
<?php if (function_exists('wp_nonce_field')) { wp_nonce_field('s3bk-updatesettings'); } ?>
<input type='submit' class="button" name='backup' value='backup'>
sorry for the rookie question just really want to get my head around whats actually happening???

progress bar whats actually happening

If I understand properly, you want to audit just some of your data for changes (as opposed to having a full DB backup) and to be able to selectively roll them back to a previous state.
If that's what you want to do, you may do that from within sql by using a "audit" table and populating it via triggers on the table where your original data is stored (i.e. each time a row is inserted/updated/deleted the trigger will write on the "audit" table what the previous value was and when it was changed).
See here for an example.

I'm looking for some feedback as to what is the best way to back data up from a sql server database which can be restored at a later date. This back up needs to be in a file which the user can use to restore data at a later date.
Does anyone have any ideas or examplea as to the best way to do this using C# and Sql Server?
EDIT:
This shouldn't back the whole database, just a set of data specified by the user using dates.
Thanks

C# Backing up data to file which can be restored later

I have done something similar. Two things were key to making this architecture work.
The image files must be stored in a consistent location relative to the Core Data store file.
The URL/path stored in Core Data for the image is a relative one, not absolute. The image path is made relative to the Core Data store file.
Relative Location on Filesystem
I stored all images in a subdirectory named "Images" that lived in the same directory as the Core Data store file. E.g.
parent directory/
--> MyCoreDataStore.sql
--> Images/
-----> SomeImage1.png
-----> SomeImage2.png
Essentially, I treat the application's data as a file package: a directory containing multiple related files that all together comprise the application data or data document.
Relative image URLs
URLs (or paths) to images must be constructed at runtime. The Core Data store holds a relative path/URL to each image's location. The location is relative to the location of the Core Data store file. Your app always knows the full path/URL to the Core Data store.
I build the full path to an image location when needed using the parent directory of the Core Data store file and the relative image path held in the Core Data db.

How to backup Core Data sqlite file with image for my iphone app?

If you don't have binlogs enabled, or cannot be sure at which point your backup snapshot was made trying to get the datadir running in another server is about your only option. (Which for maximum possibility of recovery should be as much like the original as possible in MySQL version and other environmental data).
If you do have active binlogs, look at this manual

Okay, heres a easy one for all you mysql folks out there:
Our Win 2003 server crashed last night (durring installing of windows updates). We were able to restore old data from backup, but we miss 22 hours of data. We cannot start windows and therefore not access the data through mySql admin which is the program I use normally to make backup. We have however been able to copy all data to external harddisk.
How do I access these data usning MySql Query browser and MySql Administrator tool?

access mySql database on file basis

Dropbox is available for Linux.
You could also investigate unison.

I am developing a webapp that will be used on LAN mostly. I have different locations where I deployed this app. Some of the locations run windows and some run linux (no x-window system). I need to know if there is a software out there that could easily synchronize my files stored somehere in the cloud (the clouding service can be provided by the app developers or to use different clouds) on both linux and windows machines. My english is a bit rusty so i'm going to explain this in simple words.
I will work on my local machine. I want to upload the files somewhere on the cloud and the clients installed on the LAN servers should synchronize the files. The client must be available for linux under console (as a daemon if possible) while on windows it can be something like dropbox or ubuntu one.
Does somebody know of such an app?

@Boyd: Import the dump file locally using
mysqldump -d -h localhost -u root -p thedatabase > dumpfile.sql
Then export just the structure using
mysqldump -u username -p --no-data thedatabase > newdumpfile.sql

I've got an .sql file, it's an database backup from four years ago. This .sql file is filled with table creations but also data dumps. Because I actually don't need and want the data I'm looking for an way to extract all the data dumps from the .sql file. So that I'm only restoring the tables architecture.
I think the .sql file was generated by cPanel backup service.
Is there some automated way of doing this? I can't do it by hand because the .sql file has an enormous amount of lines.

The suggested solution with mountable file systems are barely usable though. And that is exactly why you need rdiff on the server, as it makes delta calculations and optimizes the throughput by sending only information needed as a result. Otherwise why even bother using rdiff at all ...

hwo it works?
rdiff access file systems of connect to the rdiff on server?

why rdiff backup needs to be installed on server end as well?

Two things:
Did you try with "New Configuration" option while restoring? I believe the problem is related to the users/groups added to the site and those users do not exist in new environment!
Also can you try restore using PowerShell with -Force switch parameter and see if that is successfull?

We made a backup of a web application through the central administration to move it to a different server on a different domain and it's a domain controller actually.
So we made a restore operation on the destination server from the central administration but never managed to succeed.
with errors like: Object failed in event OnRestore. For more information, see the spbackup.log or sprestore.log file located in the backup directory.SPException: The specified user or domain group was not found.
I tried every user account possible with no success. any clues?

Try
7z a %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%.7z *.* for (YYYY-MM-DD)
or
7z a %DATE:~7,2%-%DATE:~4,2%-%DATE:~-4%.7z *.* for (DD-MM-YYYY)
(*.* is the mask for the files to back up)

I'm trying to setup 7zip for automated backups but I'm having trouble with output file names.
I tried using the %date% command but it just made 2 directories within my backup.
C:\Users\Desktop\Sun 11\07\2010.7z
How can I make it just log the day and month?

How can I output weekday and month in batch (log files)?

You can do either a full dump or an incremental. The chief problem with an incremental is that several backups are needed to reconstruct the data. A full dump is a stand alone all-inclusive data set.
Which one you choose depends on several factors:
how big the dumps are
how fast the repository changes
how reliable the repository storage system is
availability requirement for the system during backup
how long an outage is tolerable in case the repository dies
how conscientiously the backups are done
probably several other factors (it's late)

I'm a subversion noob. I was plannig to take backups from the repo using this command:
svnadmin dump C:\Repositories\Dev > D:\backups\repo_dev.bak
My intention is to put this into Scheduled Task (Windows Server 2008) and run this on daily or weekly basis. Can I use this command only (old backup is replaced by the new one) or do I need incremental backups separately? Or hotcopy backups?
