There's also performance internal to the tsm server to consider. The large server backups could be monopolizing your network throughput, scsi card throughput, pci/pci-x bus throughput, or some combination of all the above.

>>> [EMAIL PROTECTED] 10/24/2005 1:06 PM >>> Hi, I would like to know how to explain a situation in which when 1 or more incremental backups of some large 2 TB 5+ million file servers are running there appears to be an affect on any data restorations. If I cancel those backups, the data restorations start running much faster. So far my idea was that since the 'txngroupmax' was cranked up on those large servers that TSM wont allow the restoration to allow its next batch of files to restore until that large backup has hit the txngroupmax point. But this would mean that TSM is not very 'parallel' in its backup/restorations, but 'serial'. It also could have with the 'resourceutilization' at 6 for those large servers as well. However during this time period there are 10-20 other backups running of other smaller servers, cancelling them did not make as big a difference as those large ones. I think the underlying problem could be not very good database performance, but that still doesn't satisfy my problem of if I just cancel those backups restorations speed up. Any insight into this phenomena with TSM could help me.
