Harold:
   For what is worth, been there, done this.

  Yes, adding the EXCLUDE.DIR statements will improve backup performance - 
AFTER the first backup, during which the client will tell the server to expire 
all the files and folders that are no longer backed up.  If you delete the 
filespace first, then you avoid this performance hit - but you lose the older 
data already stored in TSM (which I’m sure you know).  We’ve let customers 
choose, because they better than we do the value of that older data..

Hope this helps
