When to Use Amazon S3 Batch Replication
◻️ Replicate existing objects – use S3 Batch Replication to replicate objects that were added to the bucket before the replication rules were configured.
◻️ Replicate objects that previously failed to replicate – retry replicating objects that failed to replicate previously with the S3 Replication rules due to insufficient permissions or other reasons.
◻️ Replicate objects that were already replicated to another destination – you might need to store multiple copies of your data in separate AWS accounts or Regions. S3 Batch Replication can replicate objects that were already replicated to new destinations.
◻️ Replicate replicas of objects that were created from a replication rule – S3 Replication creates replicas of objects in destination buckets. Replicas of objects cannot be replicated again with live replication. These replica objects can only be replicated with S3 Batch Replication.
