I am not sure I am grasping everything here but do you have all duplication
going to the 10 drives presented to the master server? Do you have SSO setup
to present the 10 drives to all media servers? I believe it is slow because
of the design of your backup environment. The master server should have
the least amount of backups/duplication going to it. I am assuming you are
doing D2D2T. It sounds like when you are duplicating, you are duplicating
images from one media server to another media server, which is basically
IP traffic. You should setup duplication of images locally, meaning if Mediaserver1
performed the initial backup then Mediaserver1 will "duplicate" those images
to tape (LAN-Free).

I think using SSO should speed up your duplication. If you rework the configuration,
each media server's duplication will be done LAN free (assuming you have
a fabric connected tape library).
