I just noticed that :-( After looking at the available_media , it appears
that tapes themselves have thier own retention because they are different
from the ones I programmed in the classes. I'm not going to be able to
restore properly if the tapes are overwriting themselves when I don't want
them to... I don't see any option to change this is media manager...

You don't have to add up the k yourself. The status and kbytes are both
reported with the bpmedialist command. Since capacity w/ compression is
always going to vary, looking at the kbytes and then subtracting from 70GB
is
not a good way to tell if the tape is full. It might be full and be way
below
this or it might be more than this and report a negative result (and still
have space left). The status will tell you if it's full.
available_media report is in the goodies dir and there is a GUI report in
the
NT console (which can be used against a UNIX master/media server). Most
people modify the available_media report because it is VERY slow (more media
servers the slower it is) or rewrite it in PERL.
If you only have 8 tapes in a small changer, be aware that the media server
may be using more than one tape at a time, and not filling one then going to
the next, because of different retention levels.

I'm using Veritas Netbackup 3.4 with 3.4.1 patches in Solaris 8 and DLT 8000
with 9 tape library ( well 8 plus a cleaning tape ) . As the backups are
running is there an way to monitor how much tape is left? I'd like to be
able to get a sense of when I need to swap out tapes before i run out. I
don't think going to all the tapes in the library, adding up the k written
to tape and doing subtraction is a optimal thing to do.
