thanks for advices folks.
It was indeed user error with being in a rush and blurred eyesight 
mistook "%" for "#"
We are making progress.
Appears that to retain permissions need root at both ends of rsync.
Have keys working with ssh for users to NAS ( not helped by default 
permissions for .ssh files being wrong) and can su to root so now need 
to get ssh working with keys with no passphrase for root and all should 
be good.
