My view is that there are PC class tapes and real tapes. Real tapes
include classic half inch reel, DLT, and presumably IBM' cartridges haven't used those).
I'll go along with that. I've had a few problems recovering data from
8mm and 4mm tapes -- in the latter case it's been the drives that were
troublesome, rather than the media -- but not with DLTs or 1/2" magtape
(except for very very old ones). I've never used QIC tapes, though
some of my friends seem to think the bigger ones are OK.
It doesn't help when trade press reviewers
don't take data integrity
seriously. Some years ago there was a review article about backup
software. The reviewers did some restore testing. Good of them to
do
that. Some of the programs tested didn't reliably
restore data, so
they were docked 30 points or so.
That's amazing. The only correct answer would be to unconditionally
flunk such programs, because the value of a backup program that can't
restore reliably is obviously zero, not any higher value...
I agree. If it won't restore, you'd be better off not bothering at
all, and saving the money (and time).
