This functionality is coming to Amahi soon, but until then there is a simple way to automatize automate it. This can be done using [http://members.multimania.cosourceforge.uknet/wipe_outprojects/automysqlbackup/ AutoMySQLBackup] script.

* Backup mutiple multiple MySQL databases with one script. (Now able to backup ALL databases on a server easily. no longer need to specify each database seperatelyseparately)* Backup all databases to a single backup file or to a seperate separate directory and file for each database.

* Can specify maximun maximum size backup to email.

* Every day it will run mysqldump and gzip will dump your specified databases to the ''/var/hda/files/dbdbbackup/daily'' directory, it will rotate daily backups weekly so you should never have more than 7 backups in there.* Every Saturday it will again backup the databases you have chosen but they will be placed into ''/var/hda/files/dbdbbackup/weekly'', these will be rotated every 5 weeks so there should never be more than 5 backups in there.* Every 1st of the month it will create a backup of all databases and place them into ''/var/hda/files/dbdbbackup/monthly''. These will never be rotated so it will be up to you to do your own house keeping. I would suggest taking a copy of this offline every month or two so that if you have a hard drive failure you will be able to restore your database.

<br /><b><u><big>Ubuntu</big></u></b>* install via apt-get sudo apt-get install automysqlbackup* edit the config file located at <code>/etc/default/automysqlbackup</code> sudo nano /etc/default/automysqlbackup* At the bare minimun, in the config file, edit the BACKUPDIR variable* run automysqlbackup to see if it works (you should get backups added to your backupdir directory: sudo automysqlbackup* Edit cron: sudo crontab -e* add the following for running cron everyday at midnight 0 0 * * * /usr/sbin/automysqlbackup<br /><b><u><big>Fedora</big></u></b>* Create a share called '''Database''' with the path of 'dbbackup'/var/hda/files/db''.
