As I recall, rsnapshot uses the --link-dest option of rsync.  I was going 
to suggest rsnapshot as a way to do versioned backups that only copy the 
amount of information necessary to capture changes.  It's the best of 
both incremental-backup and full-backup worlds.

And with the way disk sizes are ballooning these days, it's a lot cheaper 
to do rsnapshot to disk than to backup to tape.

The biggest problem I've found is that dealing with the backup disk with 
any directory-traversing program takes forever.

rsnapshot was based on Mike Rubel's "rsync snapshots" concept.
