At least with the 4.3bsd ftp program, you don't need to have room for
your dumps on the workstation.  Essentially all you have to do is

	ftp bighost
	user xxx yyy
	cd zzz
	account www
	binary
	put "|dump 4uf - /filesys" remote-filename
	quit

Where xxx is the user name on the remote host, yyy is the password,
and zzz is directory and account information, if needed.

To do a restore, you basically just reverse the procedure, e.g.,

	get remote-filename "|restore ivf -"

Of course you can do all this in a shell script run in the middle of
the night, and you can be arbitrarily fancy.  E.g., ours figures out
what level dumps to take, and removes old dumps.
