In regard to: Re: [Networker] Volume capacity?, George Sinclair said (at...:

If NetWorker actually knows about the type of drive you have, then I
would just leave volume default capacity alone.

Well, one reason would be that if on average you're getting 2:1 compression then NW will report the tape at 100% when it's only written, say, half of what it will end up writing, right?

That's true, but I guess I don't consider that a useful reason to change
the default volume capacity.  There's no guarantee that you're going to
get 2:1 compression on any particular set of data, so why change the
default volume capacity, assuming you will?  What have you gained by
changing it?  Now you have some tapes that say "99% used" when they're
full?

Or are you assuming 2:1 compression and using the 800 MB/tape number to
track jukebox capacity?
