Whups. I made a serious error with the LVM volumes above. You would end 
up removing your database partition. Not good.

It should read like this:

/bin/mkdir /mnt/mysql-snapshot
/sbin/service mysql stop
/usr/sbin/lvcreate --permission r -L16G -s -n dbbackup /dev/mysql/data
/sbin/service mysql start
/bin/mount -r /dev/mysql/dbbackup /mnt/mysql-snapshot
/usr/bin/rsync -Saq --delete /mnt/mysql-snapshot/ /var/lib/mysql-backup/
/bin/umount /mnt/mysql-snapshot
/usr/sbin/lvremove -f /dev/mysql/dbbackup
