• You can specify the storage class (default is to maintain the same)

• Replication Time Control - Adds a guaranteed 15 minute replication timeline to keep buckets in sync
• Replication is not retroactive & Versioning needs to be ON

• NO system events, Glacier, or Glacier Deep Archive
• NO DELETES are replicated
