Question on folder sync with "directory name translation"

I should describe the problem more in details, but I believe this is off
topic for this list.
The FolderA is named "Musica" (in Italian) because.. I like it that way..
and is in my home folder.

PC # /home/gionata/Musica

FolderB MUST be named "music", in my home folder on the NFS filesystem,

NAS # /volume1/homes/gionata/music

*because the synology media parse service only indexes the directory name
music in the user home dirs!* (Damn Syno...)
So I have different name on different system for the same folder! I could
change the name on my home, do it in two runs or do some symlinks.. but I
was just wondering if a more elegant solution could be found within rsync.


Anyway I can login with ssh as many time I wantm with RSA key pair. Even
multiplexing is not necessary, but thanks anyway for the info.

I hope now the problem is more clear. Is not even a real problem.. :)
