title: Is there an equivalent to Visual SourceSafe's Shadow Directories in other VCS?
body: <p>I have been asked to save the current versions of all files in all repositories on our Subversion server to a network drive. 
  This is in addition to our backups of the repositories themselves. </p>
  
  <p>Visual SourceSafe did this automatically by means of shadow folders.</p>
  
  <p>Is there a way to accomplish this for a Subversion repository?</p>
  
  <p>Is there an equivalent to shadow folders in any of the other current or popular VCS solutions?</p>
