I've seen these drives get over 50 mb/sec when cloning. So I know
they are not the bottleneck.
In that case, increasing the target sessions for each drive (maybe
double them) and increase your server parallelism by 4*4 = 16 might
help. Note that your NetWorker server license might prevent you from
boosting the server parallelism, but it will tell you if that's the
case.
Also, if any of the clients you back up have more than four disk
mount points, you might try boosting that client's parallelism in the
client resource. Before you do that, you need to keep in mind that
users of that system may hit you because boosting client parallelism
for a machine that's not powerful enough to handle the work will
cause it to be bogged down while it processes the added workload.
You might want to install a performance monitoring tool on your
NetWorker server and let it track processor load for you. You can
certainly look at the task manager during the backup window and see
what's up, but a real performance monitoring tool would give you more
insight into how your server's resources are being used. Being as
though I primarily work on Solaris and Linux, I can't recommend a
specific tool, but I am sure some others on this list can.
