Then you get the tape from the (day, week, month) prior from offsite
storage. How many hard drives are you planning on buying?

Well, it's not particularly useful for disaster recovery, only for
recovering from user error, and the usual goal of a backup plan is to
insure against data loss from both disasters and user error. Disaster
recovery tends to be the one that's crucial to keeping a business running,
though, and it's also the trickier one to manage, so it tends to get
priority, at least in an enterprise setting.
