Another option is to bump-up your ethernet... are you already running a gigabit ethernet? We've actually bumped up the TSM server and the large unix clients to Gigabit Ethernet, and it improved the throughput of the backup.

That can speed up backups of large databases dramatically. Assuming you're backing up over the lan, have you experimented with compressed vs non-compressed on the client side. Data bases typically compress very well and its possible the time saved in transmission will more than make up for the time spent compressing on the client. David Ehresman University of Louisville >>> [EMAIL PROTECTED] 11/8/2004 10:39:02 AM >>> Hello TSM guru's I have a backup that is 224 GB database and is growing. It is a cold (brings down db) backup that lasts 4 hours due to collocation and running straight to tape, we have a multitude of issues why we cannot run a hot (keep db up) backup on this particular one. Still giving us 56 GB an hour not bad. We run on a 3494 tape library hooked by SCSI straight to the AIX SP frame where the TSM server is. My problem is that as it grows it seems to be creeping close to the kill backup window from 01:00 am to 05:10 (kill backup time is 05:45). I only have 300 GB of disk being used by the other 100+ backups, 700 GB's worth. Here are the options I gave my superiors. It is currently running at 55.945 GB per hour going to tape (1 tape drive (collocate)), pretty good for tape drive speed. Disk would make the backup run faster with multi-streams. Cannot go to multi-tapes due to slow recovery. Other option would be to break the backup into 2 separate backups running simultaneously, probably nightmare admistrativewise. I said I would ask y'all if I have any other options. Please help, if anybody can. I thank y'all in advance.
