After the snapshot has been created, you can back up the snapshot while your services and databases are in normal operation. </quote> Applied to backing up a MySQL database http://blog.dbadojo.com/2007/09/mysql-backups-using-lvm-snapshots.html Of course you can also create LVM groups dynamcially with loopback http://www.howtoforge.com/creating-portable-disksafes-with-loopbackfs-and-lv... -- Wisdom is earned through bitter experience.
