FWIW, I've never had a problem with reliability of the tapes - it's the
drives which fail ridiculously often.

These days I have enough storage that I backup to spare 'offline' hard
drives and 2 copies of everything on DAT, plus I keep two working DAT
drives around at all times just in case one suddenly dies on me (as
happened *again* just a few weeks ago).

As with Teo I use DDS2 drives so the amount of data on any one tape
isn't *that* big (for the same reason I use lots of small-capacity hard
disks rather than one big one)

I still regret selling my DLT 7000 drive a few years ago. I got it free
when it was thrown out from my old work; it had been dropped and the
mechanism shifted inside and jammed - only someone had lost the
paperwork and it couldn't be returned under warranty so just got
chucked. Ten minutes with a screwdriver and it was operational again.
Wish I'd kept it now...
