S3 replication
Even with its high durability guarantees, there are numerous cases where you need to devise a plan to protect your data in case of regional outage or loss. You might even want to copy your original data, which is restricted by access policies, somewhere else so that another team can access that data. This is where S3 replication comes into play. It gives you the ability to asynchronously copy your data to another bucket. There are two versions of S3 replication available:
- Cross-Region Replication (CRR): This is where the objects in the bucket are replicated into a separate bucket that has been created in a different region than the primary region in which the original bucket was created.
- Single Region Replication (SRR): In SRR, objects are still replicated to a new separate bucket from the originating bucket, but both buckets are in the same geographical region.
