For data replication between datacenters, S3 users can use either S3 geo-replication or cross-region replication (CRR):
- Geo-replication is designed to improve the distribution of data across geographically distributed data networks. You can enable S3 geo-replication in the admin panel.
- CRR is used to copy objects asynchronously across S3 buckets stored in different clusters and public cloud providers. You can enable CRR by using the Amazon S3-compatible API. For details, refer to the Object Storage Orchestration API Reference.
- S3 geo-replication and cross-region replication (CRR) are incompatible. With geo-replication enabled, CRR is not available.
