title: S3 Cross Region Replication - Reverse Replication
body: <p>I currently have replication configured such that my S3 documents on us-east-1 are replicated to a bucket on us-west-2.  In light of today's <em>(gasp)</em> AWS outage, I considered failing over to us-west-2 (which appears to be online at the moment).  So, I have several questions about this:</p>
  
  <ol>
  <li>Would documents uploaded to us-west-2 be replicated back to us-east-1 once services are restored?  I suspect the answer is no since I have not found any documentation regarding bi-directional replication.</li>
  <li>If bi-directional replication does not happen and I decide to failover to us-west-2, what's the process for recovering once us-east-1 comes back online?  I assume this would require writing a script to copy all missing documents back to us-east-1.  Any other ideas or suggestions?</li>
  </ol>
