As far as I know it uses copy-on-write.. this means that you only have one copy of the data - the most recent. Snapshots are only the bytes that are different... applied (as a patch would be) to the most recent version.
I presume that there is some kind of loss - the patch must have a minimum block size for stuff to be efficient.
