TSM will  call for the copypool tape containing the data if the original
tape has a media error.

So depending on the quality of your tape and their failure
rates...........

We keep our backups /archives on different locations in libraries, so
they are regularly used to store new data and read/write errors are
detected and tapes can they be marked destroyed and the originals
recreated from the copypool.

Hi

Do any of you recall your archive tapes from offsite and verify that
the
data contained on them can be restored?.. If so how often and what
tests
do you run to verify that data?

Many thanks
