Take ADSM out of this picture!

There is no need for it.  DB2 is robust enough
to do the backups to a local tape robot.  It can manage
a backup cycle and expire old backups all by itself.
The db2 control center can now be run remotely and
over the web as a java servelet.

3T of sap data sounds 'mission critical' to me.
Tell your client to stop being penny wise and pound foolish.
Bolt on a 3494 and assign someone to manage it.
