I've seen quite some talk about various Automatic MySQL Backup scripts. Maybe I'm missing the point, but backing up MySQL databases is not rocket science. I use a very simple logrotate script:

/etc/logrotate.d /mysql-backup

/opt/backups/mysql-backup.sql {   notifempty   daily   nocreate   rotate 15   missingok   compress   postrotate   # just if mysqld is really running   if test -n "`ps acx|grep mysqld`"; then     /usr/bin/mysqldump --user=USER --password=PASSWORD --add-drop-table --add-locks --all --extended-insert --quick -A > /opt/backups/mysql-backup.sql   fi   endscript }
