For active-active replication, automatic failover occurs on `GET/HEAD` operations if object or object version requested qualifies for replication and is missing on one site, but present on the other. This allows the applications to take full advantage of two-way replication even before the two sites get fully synced.

## Cluster Replication Metrics

Metrics marked as ``Site Replication Only`` only populate on deployments with [Site Replication](https://docs.min.io/community/minio-object-store/operations/install-deploy-manage/multi-site-replication.html) configurations.
