      simply copy all the files the exist beneath
        <code class="literal">${QPID_WORK}/&lt;nodename&gt;/config</code>, assuming the virtualhost node is in
      the standard location. This will copy all configuration that belongs to that virtualhost
      node.</p><p>The technique for backing up a virtualhost node whilst it is running depends on its
