What kind of network do you have? Make sure to increase the number of
streams on each drive. With a 100Mb network you should get upto
11-12Mb/sec and with GigE network you should see a speed of at least
more than 35Mb/sec on each drive and with LTO-2 you should be faster but
network is the most important factor.

Hello ,
I have recently installd new Networker Server on Solaris 9 with L180 of
8
Drives  .
Enviromment .

Server Solaris 9 , V440  2 CPU 4 GB
Brocade Switch .
L180 and Lto-2 drives
Lp9000 HBA card on Solaris
LP10000 card on Windows 2000 and windows 2003 cluster DSN's  .

I am backing the two DSN on this networker Server , these two were
backed up
before by Veritas backup exec  and time was 3 hours and 5 respectiveyl
for
80 GB and 260 GB data size .


Now it takes 7 hours  .

I need help in making this backup faster . backup speed sometinmes goes
as
slow as 300kb/s and sometimes it goes to 45 MB/s  (!)


Following is just an idea for you to understand characteristics of
client .
