confirm that you NIC is running at Full duplex. Try an ftp to/from the
netbackup server of a LARGE (> 100MB) file. Perform both a put AND a get
from both the nb master as well as the nb client. Confirm that you are
getting proper throughput on each of the 4 transfers. If you are not, get
with your network admin on the network side, and use the ndd commands on the
UNIX side to run at full duplex.

What type of network card?
We have a backups slow down because of the
/usr/openv/netbackup/NET_BUFFER_SZ parameter. For instance we run our
backups over our IBM SP Switch and if we don't set the NET_BUFFER_SZ our
backups run very, very slow.
Not sure if SUN is the same, but it may be something to consider.

Subject: [Veritas-bu] backup taking too long
Hello,
I installed another NIC card on my Sun V880 so it could be on the same
subnet as the backup server. This took the load off the production subnet.
I created a new client on the NetBackup server for the new interface.
Unfortunately, the backup of a 35GB file system is now taking longer - in
fact, it was over 3 days until I had to finally kill the job because it
doesn't appear to be doing anything. This process use to take about 15
hours before the addition of the extra NIC card. There is no routing issue.
There appears to be some traffic between the server and client - used snoop.
I'm not using any bandwidth limiting parameter.
Can anybody give any pointers or hints? I tried searching the archives but
was unable to get anything meaningful.
Thanks.
Rene
