title: Backup on TFS Release before deploying
body: <p>i'm kinda noobie with the TFS build/releases.
  So my scenario:</p>
  
  <p>I have a build phase which is making an artifact. This artifact is deployed on a Virtual Azure Machine after some changes.</p>
  
  <p>My question is : is there any possibility to make a backup of the release of the previous version of the artifact, just to ensure if the Release Failed, to put the previous version back? 
  Is this based on the artifact or something or do i need to to it manually, with archive, copy , pasting etc. </p>
  
  <p>Thanks</p>
