Hi all,

the problem is solved now. I didn't realize that rsync is used in _daemon-mode_, and therefore it needs double colon in the remote address. Furthermore, the NAS resource name must be given instead of a filesystem's path.

wrong:

rsync (options) ./ user@DSS:/share/resource

correct:

rync (options) ./ user@DSS::resource

Things are working well now. Thanks to all who helped!

Best,

Robert
