Hard link based incremental backups are great. I do a lot of it with rsync.
There is something worth mentioning, though:

You may use hard link based backups in order to make a snapshot per week, but
if a file remains unchanged for long, all your hard links will be pointing to
the same file in your backup drive. This means if the file gets corrupted you
have no copies of it despite having 500+ "images". I have seen it happen and it
is not pretty.

It didn't happen to me, thankfully :-P BUt it pays to run some integrity checks
fro tieme to time, or at least have backups of the backup.
