Hi, Have you recently upgraded the client, and are you using scheduled backups with sessioinitiation=serveronly? >From 5.3.5.3 to latest 5.4 client I have an issue with above settings and performance. Ie, with newer clients performace drops with 70-80% when I backup larger files > 1Gb. Dsmc and sessioinitiation=clientorserver works fine.

The client has several very large files to be backed up (300-400GB). We are finding on a 1.3GB test file that we can only get a throughput of about 10MB/sec (looks like 100Mb speed) even though this client is configured on a GigE VLan. One interesting aspect just discovered is that a restore of the same file got speeds of 37MB/sec, which is about the same as an FTP of the same file from the client to the server. Client, switch, and server all set to 1GB full. At this point, I'm completely mystified as to what might be behind these performance anomalies. I would expect much higher throughput rates on all of these tests, but would be satisfied if the backup would just perform at the same speed as the others.
