I am trying to test de-duplication in TSM 6.1. I have realized next things: 1) de-duplication is applicable to storage pool; 2) reclaim process for de-duplication is working on volume level (threshold is for volume, not for storage pool). In my opinion, this difference can create quite serious problem. For example: - storage pool with de-duplication has volume size 2G; - there is a file system with size approximately 2G; - selective backup has been done 4 times and 4 volumes have been utilized approximately 100%; - logical storage pool utilization is approximately 25% (there are 4 copies of each file); - reclaimable space in each volume is approximately 0. How we can reclaim 75% of storage pool? Use very small threshold (for example, 1)? Maybe I am wrong at all and there is no problem?
