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.
