All, I am looking for feedback on using locked canisters for offsite vaulting. I have setup DRM for several accounts who used open containers and I have setup poor man's tape rotation without DRM with open canisters, but I have never implemented a locked canister solution.
The problem as I see it is that not all the data on the tapes will expire at the same time. So what will happen is that some of the tapes in the canister are available for reclamation and then return to the data center, but other tapes will not be available at the same time, this will cause the tapes in the canister to be out of sync. I have thought of 2 ways to potentially deal with this problem: 1) Every week we can create a brand new copy storage pool and backup the primary pools to the offsite pool. After 3 weeks all the data in the pool can be deleted and the tapes brought back onsite. This is not utilizing TSM's incremental backup storage pool feature, but would guarantee that a complete set of data was taken offsite each week. 2) Use either import/export or generate backupset to create fresh tapes every week. -- Joshua S.
