	Since they've spent the money to get a medium changer,
	they might as well get the jukebox license and whatever
	else is needed to use Networker with it.  None of the 
	other programs support it directly.

	The other choices are:

	o  Networker Single Server.  Included in the base system
	   but doesn't support medium-changers (last I knew).

	o  Dump; for use with UFS only.

	o  Vdump; for use with UFS or AdvFS.

	Many people use tar and cpio for backups, but these are
	archive/interchange programs and not really designed for 
	backups. When you archive something you don't necessarily 
	expect to restore it soon and if you do, you restore the
	whole thing.  With backups you hope you don't have to
	restore anything, but you want to be able to restore
	invidiual file easily for those people you can't figure
	out to use rm(1) correctly.  With data interchange you
	tend to restore the whole archive.
