Sysback Ver 3.2 mkvgback won't backup rootvg

ENV: 
     AIX: 325
     Sysback 3.2.1.14

DESC:   Customer used to have sysback 3.1.0.38 and just installed
        3.2.1.14.  But now he gets an error msg when he tries to run
        mkvgback -m \<\# of days> -d "Tuesday 390" -f/dev/rmt0 rootvg
        He gets the following error:
         you may not use this option to backup rootvg.
        He runs this via a 3rd party product that schedules and runs 
        scripts at certain times (kind of like cron).
        The mkvgback does back up the other volume groups without a 
        problem

ACT:    Verified and they had taken out that functionality 
        because there were customers who would make backups of rootvg
        using mkvgback and disappointed when they could not recover their
        system from these backups

Response:

Here is a workaround for this problem

Workaround:
-----------

mkvginfo -Sf rootvg > /tmp/vginfo1
mkvgback -S1 -f /dev/rmt\# rootvg

The -S flag is a low level undocumented command that the sysback
calls when creating a full system backup.  The 1 with the -S flag
tells the mkvgback command what file to look for in the /tmp directory

Example:

If I used this syntax
mkvgback -S2 -f /dev/rmt\# rootvg
The command looks for a /tmp/vginfo2 file

mkvgback -S23 -f /dev/rmt\# rootvg
The command looks for a /tmp/vginfo23 file
