Make a snapshot volume. ;)

The trick is, that you create a snapshot volume and you
make your backup from the snapshot volume; ie. *NOT* from
the original lv!

See the howto. Section "Taking a Backup Using Snapshots", 
http://www.tldp.org/HOWTO/LVM-HOWTO/snapshots_backup.html

"lvcreate --help" is also helpful - see "-s" or "--snapshot"
And "man lvcreate" is also good to know ;)
