title: Faster s3 bucket duplication
body: <p>I have been trying to find a better command line tool for duplicating buckets than <a href="http://s3tools.org/s3cmd" rel="noreferrer">s3cmd</a>.  <code>s3cmd</code> can duplicate buckets without having to download and upload each file.  The command I normally run to duplicate buckets using s3cmd is:</p>
  
  <pre><code>s3cmd cp -r --acl-public s3://bucket1 s3://bucket2
  </code></pre>
  
  <p>This works, but it is very slow as it copies each file via the API one at a time. If <code>s3cmd</code> could run in parallel mode, I'd be very happy.</p>
  
  <p>Are there other options available as a command line tools or code that people use to duplicate buckets that are faster than <code>s3cmd</code>?</p>
  
  <p>Edit: Looks like <a href="https://github.com/pcorliss/s3cmd-modification" rel="noreferrer">s3cmd-modification</a> is exactly what I'm looking for.  Too bad it does not work.  Are there any other options?</p>
