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
