title: Linux - copying only new files from one server to another
body: <p>I have a server where files are transferred thru FTP to a location. All files are there since transfer beginning (January 2015).
  I want to make a new server and transfer the files from first server's location.
  Basically, I need a cron job to run scp and transfer only new files since last run.</p>
  
  <p>Connection between servers with ssh is working and I can transfer files without restiction between servers.
  How can I achieve this in Ubuntu?</p>
  
  <p>The possible duplicate with the other question doesn't stand because, on my destination server I will have just one file where I should keep the date of last cron run and the files which will be copied from first server will be parsed and deleted afterwards. </p>
  
  <p>rsync will simply make sure that all files exists in both servers, correct?</p>
