I've only got a few tapes that fall into the 'permanent' offsite category -- commonstore archives of SAP extracts being kept seven years for legal reasons. Everything else is backups (continuous reclaim) or 21-day archives (some reclaim before the time is up, others sit off-site for 21 days and come back empty).
For the commonstore archives, I do the occasional audit volume fix=no for the *on-site* copy and then do reclaim or move data for the off-site volume. If I have a problem with the local version, I'll bring in the off-site copy and rebuild the local tape (but I haven't hit that yet). My intent is to never bring back an off-site tape with data on it unless I need it to rebuild a local tape. Can't help you on backupsets -- I have yet to figure out a meaningful use for them here. But, in line with your question -- what can I do to verify that my TSM database backup tape is readable/useable BEFORE it comes out of the library to go off-site? This is, to my thinking, the single biggest hole in the entire TSM functionality; I want to be able to validate that backup OR write multiple concurrent identical backups WITHIN TSM.

How do you verify your permanent offsite tapes are still valid (Audit Volume or other)? 2. How often do you verify those tapes? 3. How long will most LTO tapes take to do an Audit Volume? 4. What other tools are available verify a TSM tape is valid? 5. What is the best tool to use to verify that a "backupset" is still valid? Thanks for your responses.
