What you'd like to be able to do is "open dos" but that didn't work
from an X window even when I tried to subvert stdin etc. (sigh), so I
suggest that you hot-key to the console and type "open dos" from there.
Then when you want to go back to X you can hot-key there and back again. 
If you're not starting X in a separate HFT session then you might think
about doing so or doing "open dos" before you start up X.

I'd suggest using tar for the epoch dump, and touch a file at the 
start, and then use 
	tar cvf - `find ... -newer stamp ! -type d -print` | rsh ...
for the incrementals. If you run out of argument list room then its
probably time for a new epoch dump or switch to backup or cpio instead
of tar.

You can also use the "backup" command, e.g.
	find ... -print | backup -f - -i | rsh ...
but I found that you can't backup a disk or filesystem (the above command
is by name) unless you unmount it first (sigh).

You could also use cpio, but I'm not much of a cpio fan as it isn't a 
BSD 4.3 command.

The main advantage of using tar is that you can read the tarfile on
other machines, which is often an advantage if worst comes to worst
and you need to use the backup.
