title: (Tomcat) Backup WAR on Deploy
body: <p>Are there any built in mechanisms to backup a war file on deploy in Tomcat?</p>
  
  <p>For example, I deploy whosit.war. I want the current whosit.war that's deployed to backup to whosit-backup.war. Or if each deploy kept an extra copy of the deploy at whosit-deploy-20110317-211037.war. etc etc.</p>
  
  <p>Obviously I could add this to my deploy script but it would make my life so nice if Tomcat did anything like the above.</p>
