Explanation: agname is a required
parameter specifying the SMS aggregate group name that defines the
data sets you want backed up. It contains the necessary control information
to perform the aggregate backup. For agname, substitute
the name of the SMS aggregate group.
Defaults: None.
Note: You must define the aggregate group before issuing
the ABACKUP command. If you have specified a management class name
in the aggregate group definition, make sure that you also define
or update that management class prior to issuing the ABACKUP command.
