I have clients use separate tapes for Mon, Tue, Wed, and Thur
and four tapes for Friday.

These are DDS3 DATs and 2 years is not a problem.

If anyone is using QIC devices they can vary greatly.   You can
make up to about 30 passes on a tape when recording as you reverse
and go the other direction for each track, and then if you do
a complete verify that also adds up.

The old AT&T systems would default to >I think> 2000 passes per
tape.  These were smaller QICs and you would use at least 8 passes
on each backup, and then when you hit the preset limit you would
get a warning.  I believe the AIT also uses a warning, but I'm not
sure.

Perhaps Tom could let us know which emit the warnings.
