MySQL backup progam

I would need a program for backuping MySQL databases, preferably free.

I have a number of websites, but the backing them manually using mysqldump is a bore, and scripts are a bit unreliable.

The program should connect to the DB host, and back the DB up.


Thanks! :)

This is what I'm using and works great so far,

http://sourceforge.net/projects/automysqlbackup/

Other option:

http://mysqlbackupftp.com/


Or use MySQL own mysqldump.

This uses PHP with the obsolete MySQL extension, but it works correctly and could be easily brought up-to-date with the MySQLi extension.  You could add an FTP step, perhaps.

I use sqlyog to take schedule backup.
It takes backup in zip format so issue of size gets solved secondly since i can adjust the schedule time more easily.
