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. > Whether above view is good for one would also depend on the scale on which > you are backing up things - whether it's a small personal computer setup > or an industrial scale server. :) 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. -- Regards Shridhar _______________________________________ Pune GNU/Linux Users Group Mailing List
