Re: Backup ... do you mean Recovery products?
This is why I like the rsync and hard links option - rsync means every backup is an incremental (after the first, obviously) and the hard link architecture means that ALL of them are presented as full backups.

Obviously this would need more work in a serious enterprise, but for a smaller office, or a larger home this it works very well...
