I use lvm filesystem for DomU's and backup via lvm snapshots.


In detail:
I have Dom0 with md (software mirror) and lvm on top.
Nightly I make lvm snapshot for each DomU (make sure that it is large
enough not to overfill while doing backup).
Then I export those lvm snapshots to dedicated backup DomU which boots
on and after backup job shuts down itself.
Then remove snapshots.

I use this in production successfully for a couple of months.
