The idea of having multiple generations of backups is not to have the data physically present in multiple places, this is the role of RAID. The idea if having multiple generations of backups is that if you accidentally overwrite half your almost-completed novel with lines of ALL WORK AND NO PLAY MAKES JACK A DULL BOY and the backup tool runs before you notice it, you still have the precious data in the previous generation.
