Paul, Have you tried other backup methods and found they don't impact performance? Maybe you could try using one of the applications listed here http://www.sun.com/bigadmin/content/submitted/backup_recovery.html and see if the performance impact is less than with TSM. I suspect it won't be. If the native backup applications cause the same issues as the TSM backup, I'd say it's time for more resources. If not, then TSM tuning might be in order.

Thanks for the suggestions so far. I should have mentioned that this is for an application server who's performance is important 24x7. We do already schedule during off-peak, but even so the performance degradation caused by the TSM backup is noticed and is perceived as a problem. ..Paul -- Paul Zarnowski Ph: 607-255-4757 719 Rhodes Hall, Cornell University Fx: 607-255-8521 Ithaca, NY 14853-3801 Em: [EMAIL PROTECTED]
