=You probably want to either switch on hardware compression or
=use gzip with dump :)  That's assuming that you have a problem
=with being able to fit more on the same tape with tar/gzip :)

Am I not loosing some of the dump/restore functionality by compressing
dump's output before putting it onto the tape? Why does not _everyone_
do that and why does "hardware compression" even exist?

Dump still does a lot of things, which could've been put onto
separate programs -- notifying operators, for example...

Thanks!
