If you are wanting to back up your entire system, you need to run rsync as 
sudo.  If you don't, you'll get "permission denied" errors and nothing will be 
copied except your home directory.

what I do is :

sudo rsync -auv --exclude-from=/home/tkg/exclude_list / /backup 

The -a option includes most of the options in your list and the -u option 
tells rsync to only back up those files that have changed since your last 
backup. 

If your running a script from a cron job (in /etc/cron.daily for example), you 
don't need to use sudo.
