"This tutorial shows how you can create backups of LVM
partitions with an LVM feature called LVM snapshots. An LVM
snapshot is an exact copy of an LVM partition that has all the data
from the LVM volume from the time the snapshot was created. The big
advantage of LVM snapshots is that you don't have to worry about
open files and database connections, and you don't have to
interrupt/halt services on the live partition because a snapshot is
usually created in fractions of a second, so your users won't
notice any disruption, and your snapshot holds consistent data.
"I will also show how to restore an LVM partition from a backup
in an extra chapter at the end of this tutorial..."
