That sounds like "hard links"; I use that with my favourite backup program "rsnapshot". I like it. But: if the (only) target of the (many) hard links fails, then it fails in all backups. It's a very good idea to make monthly or yearly backups of one such hard linked backup to another disk. Viele Gruesse!
