Yeah, we use disk for backup as well. Tape is just an incredible pain
in the ass, and not more reliable in my experience. Tapes go bad and
tape drives go bad and you have to track and manage piles of tapes,
never use one more than its recommended write count, etc, etc...
They do have an advantage in that if one bit of data goes bad the rest
is still OK. Unless the tape drive eats it and spits out little mangled
bits of tape. Then most data is probably still OK but you need a data
recovery specialist to get at it.
If you just need something to recover from a failed server, or a fire,
or whatever ... short term use, then disk is great. Use more than one
drive and rotate, of course. Heck, 250 GB external drives are cheaper
and faster than 250 GB tapes! We can get the drives for $80. Just look
at the price of tapes for those AIT-3 drives.
