I'm on Solaris ASE 15.0.2 ESD #6 and I have just started experimenting with
the compression option in my dumps. I am using the "with compression="
When I am dumping directly to a tape, how can I determine how much
compression has occurred? First I was surprised to see that the backup log
only seems to give me the size of the database that was dumped. Okay, maybe
the backup server has no access to the information about how many bytes were
actually written to the physical tape. But then I tried load with listonly
and headeronly and was again surprised that the size of the volumes/files on
the tape did not seem to get reported. But maybe I just don't know how to
read that output.
I assume if I'm dumping to disk I could simply look at the size of the
resulting file. How do I get this same info from a tape dump?
