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
