The downside to using external hard drives is the possibility of a primary failure only to discover that the backup disk is bad. For really important data (is there any other kind?) you'd want to duplicate the backup drive. We do this when we want to make sure there is a zero possibility of losing the customer's data. Given the low cost of disks and the backup speed I think using external hard drives make a lot of sense. -Alex P.S.
