Backupsets aren't stored in pools so no to the question about pools! Yes, this is a good idea but only if you have the time at the end of the month to get it done. To generate the set TSM will read data from whatever tapes the client data is stored on. If there are lots of tapes, this means lots of mounts. I have not done this myself but I've done some TSM health checks on systems where they were trying to. Notice I said trying to. They weren't having luck getting the work done in a timely fashion. So, that's one negative.
The other negative is that the backupset tape is tracked in the volhist table rather than in the volume table. Therefore it is a little easier to lose track of the tapes that contain backupsets. Not a real downer but something to consider. Finally, generate backupset creates a tape from the client's active files. You are right having the client move all the data to the server for an archive can be problematic. I like the approach of using a targeted archive rather than a general archive: only archive the stuff you really need to archive, not the entire client. That should help to cut down on the amount of data you need to move. Kelly J. Lipp Storage Solutions Specialists, Inc.

I have been looking into using backup sets on a monthly bases instead of archives. I am using DLT 40/80 gig drives/tapes (10 of them). TSM 4.2.1.6 on Windows 2000, and 4.2.0 clients on about 98% of the machines. >From what I am reading I am able to perform this operation at the TSM server and it directs the output to scratch tapes. The GREAT thing about this is it does NOT touch the serves to retransmit all the data to the archive storage pool, and then to tape (which is alot of traffic!). The Backups sets would use more tapes (kind of like collocation turned on right?!). So after the daily incremental running at night, I will be able to create the backup sets ( for a monthly archive) using the current data just backed up from that node. (right?!) One question is when doing a backup set, does it also save all the inactive files? or just the active ones? Is there a way to direct all the backup sets to another copy pool to utilize tape consumption and to keep the tapes separate from the other copypools for easier search? (just a thought - but this would be a lot of extra work. Any thoughts would be greatly appreciated. Thank you Joe Cascanette The Cumis Group
