Yes it does help. Currently this concern is for
auditing purposes for a tape destruction plan.
Normally I would use until it dies but here it is regulatory
needs. I was thinking of setting
a lifespan between 500-1000 mounts. NB has it set to stop
using after 5000 mounts but I need
a decent number and wondering if 1000 is expecting a bit much
for audits.

Well unless you get problems, then continue
to use them where possible.
As soon as I get read / write issues, then
its time to throw away....
Lifespans of tapes (especially LTO) isnt
straight forward as it may seem. I think the estimate life is 20 - 30 years.
But by then, we would be on LTO17 or something like that!
Also, manufacturer of tape may come into
question. As a guess, if the tape is using 300+ mounts, then your getting good
serious use out of the tape.
Hope this may help....
Simon

How
long should you use a media tape such as Quantum LTO2 tapes?
There
is no standard concerning this but I have read a few different opinions.
I
would think mounts would be more important then writes because reading
a tape
can be just a strenuous to the tape as writing to the tape.
