Of course it's feasible!!  If corporations can backup terrabyte-sized
databases, then you can backup your comparatively puny DB.

In fact, if your data is vital to your company, you *must* back it
up.  Otherwise, poof goes the company if the computer is destroyed.

Now, it might cost some bucks to buy a tape drive, or a multi-loader,
if you have *lots* of data, but it *can* be done...

Btw, what happens if an obscure bug in the RAID controller shows is
head, and starts corrupting your data?  A table recovery utility
wouldn't do squat, then...
