What files to exclude when using rsync
 

I am trying to create a complete backup of a system (SuSE 9.1) using rsync to a usb drive. I gather there are some linux files and directories that should be excluded from a complete backup. Can anyone point me to a good and complete list of files/directories that should be excluded? So far, I understand that the following should be excluded:

/tmp/
/proc/
/media/usb-storage --> This is my usb drive itself

I'm using SuSE 9.1 so is there anything else that shouldn't be backed up when using rsync?

I would include '/dev/' as well to the list of items that should not be backed up.

Thanks. Anyone else have additional suggestions? We now have:
/tmp/
/proc/
/media/usb-storage --> This is my usb drive itself
/dev/
