CRR - Cross Region Replication SRR - Same Region Replication
- Buckets can be in different accounts also
- Copying is asyn
CRR - Helpful for compliance and lower latency SRR - Live replication between probably environments
Only new objects gets replicated, S3 batch replication feauture will replicate existing and failed replication
S3 replication isn’t chained because replication is a separate event from the original object modification. Replicated objects don’t trigger further replication.
- Optionally, we can replicate delete markers
- Deleting with a version ID (you target a specific version): That exact version is removed from the source. This is not replicated — the destination bucket still keeps that version.
Replication settings are managed at Manament tab
There are some repliation metrics that when we enabled, can be monitored
