In my experience in your scenario almost  always boils down to
Auto-negotiate somewhere along the line.

Try using bpbkar on the client writing the same data as to be backed up
to a null device , this way you can determine without network, tape
,blah blah.
That the bpbkar process is in actual fact reading the data quick enough,
if this succeeds def network prob somewhere.

Check the performance tuning guide for more detail.

Subject: [Veritas-bu] Strange speed problem...not the norm

Has anyone seen this before?

Netbackup 5.0 mp3 Solaris9 connected to L700 via fibre.

I have a network client on a 100Mb network which is beyond slow backing
up. Looking at the gui ( i know not accurate ) details for a job shows
like 127kb/s.

Doing an scp of a 128mb file from master server to the client is quick <
20 secs.
Doing an scp of the same file from client to master it gives ETA of over
an hour, which comes down to like 20-30 minutes. Obviously wrong.

So first thing on the solaris client i did was force the nic to 100 full
autoneg off. Then doing an scp seems to be quick both ways. Great.

Then launch a manual backup off for the client only and the speed is
slow. 127kb/s again.

going back and trying the scp is now slow again from client to master
server.

Whats going on?
