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).
