AFAIK snapshot doesn't take any space as long as filesystem hasn't
changed from the time when snapshot was taken.
For instance - If you take snapshot on filesystem and after that, 10MB
file is deleted, snapshot is using only 10MB space from (because it's
only difference between snapshot and actual filesystem).
