title: Copy file to backup directory preserving folder structure
body: <p>I have to copy a file in a directory, to its backup directory, preserving the folder structure. E.g. the file <code>aaa</code> in <code>MyFolder/Test/aaa</code> to <code>.MyFolder.bck/Test/aaa</code></p>
  
  <p>I tried to use</p>
  
  <pre><code>cp --parents MyFolder/Test/aaa .MyFolder.bck;
  </code></pre>
  
  <p>But the result is <code>.MyFolder.bck/MyFolder/Test/aaa</code> and not <code>.MyFolder.bck/Test/aaa</code> (which is the one I want).</p>
