title: Apache Camel: rename (S)FTP target file to prevent overwriting
body: <p>I am attempting to set up a route from one SFTP location to another, moving the files (not copying). I would like to prevent target files from being overwritten if a source file has the same name. </p>
  
  <p>My route currently looks like this:</p>
  
  <pre><code>from("sftp://camel@server1/Source?password=camel&amp;delete=true").to("sftp://camel@server2/Target?password=camel");
  </code></pre>
  
  <p>My problem is that a new file in Source with the same name as an earlier one will overwrite the target file in server2. How can I tell Camel to give the target a new name if it already exists?</p>
  
  <p>Thanks!</p>
