ftp:// error

I am sorry, the rsync algorithm needs to execute rsync on the server. 
Since ftp does not allow executing remote programs (as ssh does), even 
if there exists a rsync executable installed in the server and you have 
permission to execute it, using ftp you cannot execute it. So your 
command won't work and it will never be because it is impossible to 
implement it by the very differences of what rsync does (executing a 
remote rsync program) and how ftp works (just download files).

I hope my answer was clear to you.
