I'm been planning to use the same solution for domU backups, e.g.
lvm-snapshots, and I'm very interested in any solution to the problem.
We are using TSM (Tivoli Storage Management) as backup solution, and the
license count (read: money) would be rather large if each domU should have
a client installed. I would prefer to do it all from dom0.
How are all of You (xen-users) managing backup of Your domU's ??

Thanks,
Jorgen
