"ignore" actually deletes stuff with smartupdate

[safar]

here is my dirty solution
1. i do a full backup copying different files

2. i run this script

PHP Code:

#!/bin/bash

#this must be run as root !

externaldrivename="ice" 

#replace ice with the name of your external hard drive (if it has spaces, put a \ before each space)


for i in Applications Library Developer System usr bin etc private sbin

do  
echo "let us check what should be deleted from $i"

rsync -n -rltv --delete /$i/ /Volumes/$externaldrivename/$i/

#do check what is gonna be deleted ; when you're sure, delete the " -n " (which forces rsync to do a dry run)

done 


(i volountarily ignored /Users, because i do want to keep files on the /Users folder of my external hard drive that are not on the volume from which i clone)

hope this helps someone !
