How are you doing duplications currently? With scripts? Via the
NetBackup GUI? 

The greatest improvement I've seen are 1) using as many drives as
possible, which involves using a script and 2) Doing multiplexed backups
(using -mpx with bpduplicate; available with 3.2 and later).

You should be able to do this with the scripts you have in your
possession, you just need to look at the directions and see what they
actually do.
