You can do it your way - but you've got to shutdown the domu before
backing it up. If your root partition is an XFS-filesystem, you might
be able to dump a running domu-filesystem-image after calling xfs_freeze
(inside the domu). However, I wouldn't recommend using XFS as root filesystem.

The other option is to use some kind of network backup client in your domu
or tar/cpio/dump all necessary partitions somewhere.

I just tar all my domu's root-partitions into a network filesystem
directory.
