Remote backups are initiated from the backup server instead of the production server, so hacked servers won't get ssh access to the backup server.
OBackup can enumerate and backup all MariaDB / MySQL databases present on a server
It can also enumarate all subdirectories of a given path and process them as separate tasks (usefull for multiple vhosts).

$ git clone git://github.com/deajan/obackup.git
$ chmod +x ./obackup.sh
Once you have grabbed a copy of Obackup, just edit it with your favorite text editor to setup your environment
and you're ready to run. A detailled documentation can be found in the CONFIG.TXT file.

You can run multiple instances of obackup scripts with different backup environments. Just copy the script to another
filename, edit it's environment and you're ready to run concurrently.

## Usage
MariaDB / MySQL backups are consistent because dumps are done with the --single-transaction option.
File backups can be done directly of the data won't change while backing up but a snapshot of the actual data to backup
is preferable as it will stay consistent (LVM, zfs or btrfs snapshots will do fine).

$ ./obackup.sh TASKNAME --dry
$ ./obackup.sh TASKNAME
You may try your setup by specifying the "--dry" parameter which will run a simulation of what will be done.
$ ./obackup.sh path/to/config/file --dry
$ ./obackup.sh path/to/config/file
One you're happy with a test run, you may run obackup as a cron task with the "--silent" parameter so output will not be written to stdout.
All backup activity is logged to "/var/log/obackup_backupname.log".
## Final words
Backup tasks aren't always reliable, connectivity loss, insufficient disk space, hacked computers with tons of mangas to backup... Anything can happen. Obackup will sent your a warning email for every issue it can handle.
Nevertheless, you should assure yourself that your backup tasks will get done the way you meant it. Also, a backup isn't valuable until you're sure it's restoration will be a success. Try to restore your backups to check whether everything is okay. Backups will keep file permissions and owners, but may loose ACLs if destination file system won't handle them.
