Any suggestions?  Just exactly how would one tar one filesystem to another,
without the intermediate tar file?



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 .. )



if ! (mount /mnt/backup); then
   echo "ERROR!  Could not mount /mnt/backup!"
   echo "Abort, abort, abort!!!"
   exit 1
fi



good to manually mount backups ... :-)

rsync -uax --delete / /mnt/backup/
rsync -uax --delete /boot /mnt/backup/
rsync -uax --delete /var /mnt/backup/
rsync -uax --delete /home /mnt/backup/



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

man rsync:
-x, --one-file-system       don't cross filesystem boundaries
