Exclude.Dir and Exclude.FS preclude entry into the specified areas when the 
backup is by file system: other forms of Exclude involve entry and scanning and 
attendant overhead.  However, expiration effect rules for the two are different 
(see the manual).  You may want to commit to the elimination of the 1/3 from 
the original file system, with perhaps a safety Archive of them beforehand.
