title: Move many S3 buckets to Glacier
body: <p>We have a ton of <em>S3 buckets</em> and are in the process of cleaning things up. We identified <em>Glacier</em> as a good way to archive their data. The plan is to store the content of those buckets and then remove them.
  It would be a one-shot operation, we don't need something automated.</p>
  
  <p>I know that:</p>
  
  <ul>
  <li>a bucket name may not be available anymore if one day we want to restore it</li>
  <li>there's an indexing overhead of about 40kb per file which makes it a not so cost-efficient solution for small files and better to use an <em>Infrequent access</em> storage class or to zip the content</li>
  </ul>
  
  <p>I gave it a try and created a vault. But I couldn't run the <strong>aws glacier</strong> command. I get some SSL error which is apparently related to a <em>Python</em> library, wether I run it on my <em>Mac</em> or from some dedicated container.</p>
  
  <p>Also, it seems that it's a pain to use the <em>Glacier API</em> directly (and to keep the right file information), and that it's simpler to use it via a dedicated bucket.</p>
  
  <p>What about that? Is there something to  do what I want in <em>AWS</em>? Or any advice to do it in a not too fastidious way? What tool would you recommend?</p>
