NetBackup 6.5 slow backups over network
I am configuring a NetBackup 6.5 installation. Here is the topography:
Master server: windows 2003 R2 x64
client: windows 2003 R2 x64
client: NetApp over NDMP
The policies are configured with zero overlap in the start times. The number of data buffers is 16. We are running with no shared memory. The size of the data buffers was set at 256 KB, but this was removed to increase performance.
The master server backs up at 45 MB/s. The other windows client backs up at 100 KB/s. The logs in the Activity Monitor do not indicate any problem with either backup and there is no dwell over any open file. A rough copy test initiated from the master server was able to push 36000 KB/s back and forth between the master server and the client. Does anyone have a suggestion for improving the performance?
