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 (gasp) 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:
- 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.
- 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?
