It isn't, is it? Not unless you have a lot of money for DLT, AIT, tape
libraries, and such.
Duplicating onto additional hard drives could be satisfactory in a way,
if you have the drives on hot-swap trays. Otherwise, the same thief or
fire that nabs the main system gets the "backup". Part of the point of
tape backup is not just durability but also the possibility of off-site
storage.
And, of course, hard drives _seem_ cheap and practical until you
consider not just the hot swap problem but also the fact that it doesn't
scale economically to multiple generations.
But the people who promote that option usually aren't serious about
generational backup, anyway -- same as the crowd that used to promote
Colorado Jumbo / QIC because high tape cost doesn't matter if you only
ever use two tapes.
