A shell script to backup 4 f/s in parallel is easy,



#!/bin/ksh
dsmc i /a/b/c &
dsmc i /a/b/d &
dsmc i /a/b/e &
dsmc i /z/x/y &
wait


Started by a schedule this will run 4 backup streams to ADSM, if your
Stgpool settings are correct then 4 drives will be used.

wait means the script will not reurn and update the schedule as finished
untill a 4 streams have completed.

You wont get 4X the throughput though.

Either - use ebu with 4 parallel sessions,
or - build a shell script which back-up 4 filesystems in parallel. Not
easy.
