It's likely that you can't create files that start with . on CIFS or 
NTFS.  Try using the "--inplace" option with rsync.

No problem with . filenames in general just in this instance the 
transmission of the files is inhibited.  Apparently something is 
happening with the temporary file creation.
Using "--inplace" does the copy as desired.  There is the message about 
the permissions which are apparently inherited from the directory.

Slightly OT: if you have admin access to the NAS you might want to
consider using rsyncd (rsync daemon) on the server side. It's much more
efficient because it doesn't require rsync on your client machine to
read entire files over the network to check for changes. Rsync does
this in order to calculate deltas, but the effect is counterproductive
when it's doing it over NFS. Using rsyncd I've measured a 10x
improvement on my system (with rsnapshot, which is built on top of
rsync).
