[Veritas-bu] RE: Number of mounts before getting rid of a tape?

Some studies done in the 90s showed that tapes are a remarkably stable
medium so long as they are not subjected to temperature or humidity
extremes.  So if your tapes are in a controlled environment, it is
probably prudent to wait for errors before junking a tape.  Tape mounts
by this standard are irrelevant.

hear, hear.

They're pretty expensive, and our budget doesn't allow for replacing a
couple thousand tapes every year.  The recommended is, I believe, 25
mounts
(which works out to a yearly schedule if you're on a two-week retention)
for
DLT III/IV, but I agree with Mark.  I wait until they become
"questionable,"
and then set them up for degauss/destruction.
