@sazius real directories is what I understand rsnapshot does. Maybe attic, too. Locally (on the #NAS) I'd really like to have 'real' files, or at least they should be accessible as such. But from my reading I also understand that rsync is much faster than obnam, and obnam actually isn't very good at dedup either. No idea how that compares to attic, though. https://attic-backup.org/ http://blog.karssen.org/2013/01/04/comparing-rsnapshot-and-obnam-for-scheduled-large-backups/
