thanks for the feedback.  i see the same problems w/ cifs.   scripting  
this is turning out to be slightly more subtle than i thought.   
various combinations of rsync --delete, rsync --dry-run, tar, etc.  
_may_ be viable.   unfortunately it looks like cifs also barks at some  
of the unix tar permissions, so i may turn the whole process around  
and run it from the rsync server on the NAS, though that also has  
issues.
