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....
