i see your point. but even in that case a snapshot would be the better option.
if there really is no way to keep all attributes* the he can still dump the
snapshot blockwise and backup that. the idea of a snapshot is that it is in a
valid state, synced without any half written files or such.
not sure if lvm actually can assure the last bit for vm disk filesystems though.
