[come on ye little faithfull goumet]

How about this little strategy:

	#!/bin/sh
	backupdate=/usr/local/bakupdate
	if [ -f $backupdate ] ; then
		find $1 -newer $backupdate -print | cpio -ov >/dev/whatever
		touch $backupdate
		echo "Incremental backup finished."
	else
		find $1 -print | cpio -ov > /dev/whatever
		touch $backupdate	# create empty file.
		echo "Full backup finished"
	fi

This program above is NOT guaranteed to work, but is just an idea of
the approach. In the case above you can use ncpio if you're using one
of at&t's 3B machines.
