Hello again,
I think I am starting to realize that something needs to be configured properly
in order to Fill the tapes to their MAX capacity. I'd like some advise on that.
I can create another thread for that however, it may be something to do with
existing configuration so I am continuing the discussion here.
I am doing below cron jobs currently (no manual amdumps)

I haven't provided disklist file for both backup types. However, if needed I
can give you that or anything else.
I wonder what I can do to fill up these tapes to the full. May be use
'flush-threshold-dumped, flush-threshold-scheduled, or taperflush ' as they
mentioned here
