Re: BackupSet: Is there an efficient method to generate backupsets
Werner, on day_02 you will have 990 files still active from day_00 (bds010.1, bds011.1, ..., bds999.1) + 10 files from day_01 (bds000.2, bds001.2, ..., bds009.2) and your assumption is completely correct. What you want (as far as I understood it) is to mimic copypool behavior with backupsets and is not possible. If you are making this for only one node go the backupset way (1 tape/day) and it might be fine for you. If this is to be done for several nodes copypool is the right answer (few tapes/day + 1 DB tape/day). Copypool also allows you to recover from bad primary tape which you cannot accomplish with backupsets.

Re: BackupSet: Is there an efficient method to generate backupsets
We are looking at ways to reduce tape consumption in our 3494 library- which is being managed by 2 AIX TSM 4.2.2 servers. In general- we want to write archive data (separate management classes and storage pools) to disk and then directly to a tape copy pool, and then eject the media out of the library for long term storage-- without having redundant copies of the archive data sitting in a primary tape pool.-- Are there any suggestions on how to accomplish this-- since you can only route disk pools to primary tape pools first? TSM 5.1 allows synchronous writes to disk/tape/copy pools, but for TSM 4.2 I'm hoping to find a simple solution-- All feedback is very much appreciated- - John From: Schwarz Werner [EMAIL PROTECTED] Reply-To: ADSM: Dist Stor Manager [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: BackupSet: Is there an efficient method to generate backupsets Date: Thu, 12 Dec 2002 17:15:14 +0100 I need help, please: Can me tell somebody to solve the problem described in the following example? begin example assumption: I have 2 backup_versions time: day_00 The 1st time I create a backupset, all 1000 active backup_versions are consolidated on tape_01 {bds000.1,bds001.1, ... ,bds999.1}. time: day_01 Incremental backup creates 10 newer backupversions {bds000.2,bds001.2, ... ,bds009.2}. time. day_02 I create a 2nd backupset, all 1000 active backup_versions are consolidated on tape_02 {bds000.2,bds001.2, ... ,bds009.2,bds010.1,bds011.1, ... bds999.1}.
