# 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

export MC_HOST_sited=http://minio:minio123@127.0.0.1:9008

./mc ready sitea
./mc ready siteb
./mc ready sitec
./mc ready sited

./mc mb sitea/bucket
./mc mb sitec/bucket

## Setup site replication
./mc admin replicate add sitea siteb --replicate-ilm-expiry

sleep 10s

## Add warm tier

		info.Sites = append(info.Sites, peer)
	}
	sort.Slice(info.Sites, func(i, j int) bool {
		return info.Sites[i].Name < info.Sites[j].Name
	})

	info.ServiceAccountAccessKey = c.state.ServiceAccountAccessKey
	return info, nil
}

const (
	makeBucketWithVersion   = "MakeBucketWithVersioning"
	configureReplication    = "ConfigureReplication"
	deleteBucket            = "DeleteBucket"

# MinIO Batch Job
MinIO Batch jobs is an MinIO object management feature that lets you manage objects at scale. Jobs currently supported by MinIO

- Replicate objects between buckets on multiple sites

Upcoming Jobs

- Copy objects from NAS to MinIO
- Copy objects from HDFS to MinIO

## Replication Job
To perform replication via batch jobs, you create a job. The job consists of a job description YAML that describes

	if err != nil {
		writeErrorResponseJSON(ctx, w, toAdminAPIErr(ctx, err), r.URL)
		return
	}
	// Report the ILMExpiryStats only if at least one site has replication of ILM expiry enabled
	var replicateILMExpiry bool
	for _, site := range info.Sites {
		if site.ReplicateILMExpiry {
			replicateILMExpiry = true
			break
		}
	}
	if !replicateILMExpiry {
		// explicitly send nil for ILMExpiryStats

func TestGetMissingSiteNames(t *testing.T) {
	testCases := []struct {
		currSites []madmin.PeerInfo
		oldDepIDs set.StringSet
		newDepIDs set.StringSet
		expNames  []string
	}{
		// Test1: missing some sites in replicated setup
		{
			[]madmin.PeerInfo{
				{Endpoint: "minio1:9000", Name: "minio1", DeploymentID: "dep1"},
				{Endpoint: "minio2:9000", Name: "minio2", DeploymentID: "dep2"},

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.
