Unison (http://www.cis.upenn.edu/~bcpierce/unison/) is a nice file
synchroniser. It goes 'both ways' and is more advanced than rsync
--delete, as any new files in /storage/backup/stuff would be copied
over to /home/stuff. Not very useful for backups, better for syncing
two machines.
This page (http://www.mikerubel.org/computers/rsync_snapshots/) has a
information on snapshot backups using rsync and hardlinks.
I'd also like to give http://www.nongnu.org/rdiff-backup/ a go
sometime. The problem with the rsync/hard link appraoch is that if you
change a file, it stores the whole of the file, not the diffs. Though
one is into versioning software there.
