# Automatic Site Replication

This feature allows multiple independent MinIO sites (or clusters) that are using the same external IDentity Provider (IDP) to be configured as replicas. In this situation the set of replica sites are referred to as peer sites or just sites. When site-replication is enabled on a set of sites, the following changes are replicated to all other sites:

- Creation and deletion of buckets and objects

func (r *ReplicationStats) Delete(bucket string) {
	if r == nil {
		return
	}

	r.Lock()
	defer r.Unlock()
	delete(r.Cache, bucket)
}

// UpdateReplicaStat updates in-memory replica statistics with new values.
func (r *ReplicationStats) UpdateReplicaStat(bucket string, n int64) {
	if r == nil {
		return
	}

	r.Lock()
	defer r.Unlock()
	bs, ok := r.Cache[bucket]
	if !ok {

		writeErrorResponse(ctx, w, errorCodes.ToAPIErr(ErrReplicationPermissionCheckError), r.URL)
		return
	}

	replica := r.Header.Get(xhttp.AmzBucketReplicationStatus) == replication.Replica.String()
	if replica {
		if s3Error := checkRequestAuthType(ctx, r, policy.ReplicateDeleteAction, bucket, object); s3Error != ErrNone {
			writeErrorResponse(ctx, w, errorCodes.ToAPIErr(s3Error), r.URL)

	// Header indicates if its a GET/HEAD proxy request for active-active replication
	MinIOSourceProxyRequest = "X-Minio-Source-Proxy-Request"
	// Header indicates that this request is a replication request to create a REPLICA
	MinIOSourceReplicationRequest = "X-Minio-Source-Replication-Request"
	// Header checks replication permissions without actually completing replication
	MinIOSourceReplicationCheck = "X-Minio-Source-Replication-Check"

	ReplicationTimestamp = "replication-timestamp"
	// ReplicaStatus - this header is present if a replica was received by this cluster for this object version

	// ReplicaTimestamp - the last time a replica was received by this cluster for this object version

  - [beta] `Federated Replica Sets` create and maintain matching
    `Replica Set`s in some or all clusters in a federation, with the
    desired replica count distributed equally or according to
    specified per-cluster weights.
