in this case i'd use a snapshotable filesystem (e.g. btrfs) plus rsync.. this 
has the advantage that you work on a filesystem level with direct access to 
your backup.
i heard obnam works well as well.
another alternative would be rsnapshot.

what about somebody steals only the harddrive?
or the harddrive malfunctions, you cannot delete it and you'll have to discard 
it.

another reason not to use duplicity in your case. there are better alternatives 
for your use case.
