Hello Mark,
That should have been backups instead of restores I was thinking of two things at once. But restating my thoughts. 1) Could other workload be affecting the performance of your backups. 2) Could the priority of the process used by the user backup be at a lower level then those used by the master scheduled backup.

Thanks Len No restores were running, backups only.

Hello Mark When the restores were running on the master/media/client systems, did they both have the same level of usage outside of the restores. That is was the cpu busy, i/o usage pattern, network usage etc at the same levels for both restores. If the user backup was running when the systems was under heavier usage and the master scheduled backup was running when the systems was lightly used, this might explain your differences. I am not sure how much different the process flow for a user backup vs a backup scheduled from the master. But it might be the relative system priority of the inet.d started processes vs the process's started by the user backup. len From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, July 04, 2007 10:03 AM To: [email protected] Subject: [Veritas-bu] Performance issues with user initiated backups. Hi all Environment : Master Netbackup 6.0 MP4 Solaris 10 Media server 6.0 MP4 HP-UX 11 IBM 3584 Library San Attached IBM LTO2 Drives Media server is the oracle client too so it's a local backup. Data : /u21/oradata/D1 118gb 169 files User Backup of above writes to drive1, tape1 at 13mb/sec Scheduled/immediate backup writes to drive1, tape1 at 27mb/sec We believe that there is so much communication going on between all the netbackup processes regarding files and updates when a user backup is run. Can anyone think of anything else that would slow this backup down to half the speed. We have done numerous tests on different drives, tapes and even chosen different data locations, and come up with the same results. Cheers
