Xen users - Sep 2008 - domU OS backup and restore best practices

What are the best practices for backup and restore of domU for different
back-end such as file/lvm/raw disk etc. Also, different scenarios for guest
running on 32bit and 64 bit dom0.

i think it''s best to treat DomU''s as real machines, and do
networked backups.

trying to backup the storage form Dom0 without cooperation from DomU
opens a lot of inconsistency issues. (the filesystem isn''t cleanly
unmounted, data files might not be completely written, DBs aren''t
flushed, etc)

we use disc images for the domUs. I just copy them once a week while 
they are shutdown. This causes 10 minutes downtime but we can live with 
that solution. We think of doing snapshots on the SAN LUNs
