In the sense that I can't use 'iostat' to check the speed, yes. I think
windows would have the same issue as well.
In the sense that NetBackup isn't reporting on the speed, then I imagine
it's common to all platforms.

Yes. Solaris iostat shows tape devices. Apparently Linux iostat does
not (at least I have not been able to make it do so).
Now that my duplication is complete, I can hand-calculate the average
throughput for the entire operation. But that's not available to me
during the process to see how it's going....
