Are the VMs still running while you do this ?
If so it's no surprise that the dom0 panic: one of its mounted
filesystem got modified in its back ... you can't have the same filesystem
in use by 2 different OS instances at the same time.
You would need to snapshot and do the backup from the VM itself.
