[OpenAFS] rsync on afs-client

The client cache will request complete files from the fileserver.  rsync 
will then have to examine the file itself and determine what an 
'incremental change' is.

This is not an acceptable method.  AFS backup preserves ACLs, rsync does 
not.  Your solution will require one full backup for each day of the 
week.  How else do you propose to do a restore if some files have 
changed but others have not?  Learn how to use the AFS backup system, it 
is simple enough to get a basic backup schedule in place.  If you have 
more specific questions ask them here, or read the AFS Adminitrators Guide.
