As mentioned in my original reply, that should be what 
ftplib.FTP.rename() does under the covers[1].  However, the OP 
was asking about copying a file, not renaming a file.

John mentioned the poorly-supported "server-to-server copy", but 
from my understanding, I think that still slurps locally and then 
pushes it back up elsewhere.

taken from ftplib.py:

     def rename(self, fromname, toname):
         '''Rename a file.'''
         resp = self.sendcmd('RNFR ' + fromname)
         if resp[0] != '3':
             raise error_reply, resp
         return self.voidcmd('RNTO ' + toname)
