I don't believe that Centoss yet
capable of such feature, live backup is recent and FAIK its
available on Fedora 17/18.
To workaround this issue I use DRBD and LVM snapshot.
This feature is a must have since it's capable to snapshot
disk-only (ie. qcow2), making easier to rsync and copy a entire
disk without having the hole storage allocated or having big lvm's
back and forth.
Hope I helped

Hello to you all!
We are implementing here at the University KVM virtualization for
our servers and services and i was wondering if anyone try to
automatically backup images.
I am actually using logical volumes for the VM guests. All virtual
clients are installed in their LVM logical volume. We are already
use IBM TSM for backup as we used to when we had physical
machines, ie install client in OS and manage files and data
backup.
I want to have an image backup additional to files backup, but i
want to take the image online, without pause or suspend the VM
guests.
Did anyone try to create image backups online? What about http://wiki.qemu.org/Features/Livebackup?
Can you please advise?
