So here's the question. NDMP backups come into the filepool and identify duplicates is running. But because of those long retention times, all the volumes in the filepool are FULL, but 0% reclaimable, and they will continue to be that way for 6 months, as no dumps will expire until then. Since the dedup occurs as part of reclaim, and the volumes won't reclaim -how do we "prime the pump" and get this data to dedup? Should we do a few MOVE DATAs to get the volumes partially empty?
Would RECLAIMSTGPOOL help you here? Original usecase was a disk stgpool to permit those with a single drive to put the data somewhere whilst reclaiming, and the reclaimstg would then eventually drain back to the primary stgpool. But you might have the NDMP data filter into a pool in which you force reclamation of _everything_, and have it debouche into another stg. I know that dedupe is per-pool, but I seem to recall that it works to move from a dedupe pool to another dedupe pool? - Allen S. Rout
