Dear Rudi Servo,
So you actually have to power off VM guest to take the LVM
snapshot and then synchronize the disk with DRDB.
Do you automated this procedure using a cronjob or anything
similar? Did you restore an image with success?
Thank you all,

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?
