mount /new-disk /mnt/new
-- abort -- abort if failed
tar cf - /home /var /whatever-you-want | ( cd /mnt/new ; tar xvfp - )
umount /mnt/new

	- you can figure out what directories to cp over and which ones yu
	don't touch
	( /tmp, /mnt, /proc .. )

good to manually mount backups ... :-)

wouldn't the first rysnc of "/" backup everything including /boot, /var...
	- and worst still, rsycing of /tmp and /proc is a very bad idea

	which means you manually list all the directories you do want 
	rysnc to the other box


and i dont like --deletes, just in case i delete a directory/file 
and a week later, i decide, oh shit, wish i had that file from last
week or last year

and nope, i dont use rsync ... except to d/l and [r]sync other peoples
stuff like kernel.org locally
