Depends. Some things don't adopt to revision control. e.g. photos that I have
shot in past 5 years have accumulated to 20GB. in mercurial, that would waste
another 20GB for repo + 20GB for working copy, even without a single change.
I admit that even I do not use snapshots on btrfs. The only time I have needed
the backup restore was when I was moving between machine and instead of
rsyncing 10+GB, untarring was easy.

:) My personal machine has about 80GB of data that I care about and duplicated
on 2 drives. on my $DAYJOB, thats about 700GB spread over 20 people, not
counting any repo.
So the scale is about the same if you ask me.
