I think the iostat command for linux is different....BUT...You can look at
the bptm log files on your media server and get information about the
duplication speeds.

look for "successfully wrote" and "successfully read" in the bptm logs to
get write and read speeds for the duplication process.

You can also get similar information on the master server with the bperror
command...but it might be easier to get it from the media server bptm logs.

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....
