Just thinking out loud...
 
I echo Ed Wilts inquiry about file size. If you have millions of small
files that will slow you down substantially.
 
Have you checked for overall network throughput? Specifically, would you
be able to verify that the NIC is set to 10/100/1000 (whatever you line
speed is) full duplex. Duplex mismatches cause headaches. Speed
reductions do to. We have had speed reductions on the swich port on two
separate occasions after bouncing the switch. You can verify duplex
mismatch on your end (if you are working with a UNIX client) by checking
for collisions or errors with outgoing packets.
 
Good luck,
 
Bill

Subject: [Veritas-bu] Netbackup 6.0 Performance Very Slow


Recently I Installed Netbackup 6.0 MP3 in our environment with the
following architecture.  1 Master Server and 2  Media Server. I am
taking file server backup
of Mapped Drive of SAN with 730 GB of Data. This is the same server in
which Media Server is attached . I am having LTO 3 Robotic Library with
28 Slots (HP MSP 6000 Model). The Backup takes 30 Hours to finish entire
730GB at 7000 KB/ Sec (6MB/Sec)  of data and i tried all the performance
tuning mentioned in Netbackup guide.  Nothing worked. Anybody does the
tuning and any suggestion to reduce my backup windows
