# 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

		if err != nil {

	// Add a version with tiered content, one with local content
	xl := xlMetaV2{}
	counter := 1
	report := func() {
		t.Helper()
		// t.Logf("versions (%d): len = %d", counter, len(xl.versions))
		counter++
	}
	fi := FileInfo{
