NetBackup Gurus,
        If I have a storage unit with 4 drives that is configured to
handle multiplexing up to 4 streams per drive, and I have 2 classes,
both configured to multiplex 4 streams, will this configuration send 4
streams to two drives and leave the other 2 drives idle?
        Also, if I configure a class to send multiple data streams, then
set it up to send 4 streams of data (to the storage unit with 4 drives),
will it backup AND restore from the 4 drives simultaneously?
        Thanks for your help.

Darryl
