I'm following this strategy for several years now, in in case I need to 
restore from such a "backup", I use cp --reflink when copying the snapshot over 
the original. 
Without the --reflink you'd get a completely new copy of your snapshot, and 
when producing new snapshots they will not have anything in common with your 
previous snapshots --> more disc space.
