title: Automate export (backup) of Trello boards
body: <p>When logged into trello in a browser you can easily backup a board by hitting a URL like this:
  <a href="https://trello.com/board/replaceWithMyBoardId/my-board-name.json" rel="noreferrer">https://trello.com/board/replaceWithMyBoardId/my-board-name.json</a></p>
  
  <p>I'd like to write a script that will go through a given set of boards and automatically archive the json export.</p>
  
  <p>I've already got a developer key, and I've already got an oauth token.  I can successfully go to <a href="https://api.trello.com/1/board/replaceWithMyBoardId?key=replaceWithMyKey&amp;token=replaceWithMyToken" rel="noreferrer">https://api.trello.com/1/board/replaceWithMyBoardId?key=replaceWithMyKey&amp;token=replaceWithMyToken</a> but that only gives me basic board info.  I want to get the full board export like I would through the browser.  </p>
  
  <p>Any ideas? </p>
