replication is configured, any incoming uploads and metadata changes to versions created on the target, will sync back to the source and be marked as `REPLICA` on the source. AWS, as well as MinIO do not by default sync metadata changes on a object version marked `REPLICA` back to source. This requires a setting in the replication configuration called [replica modification sync](https://aws.amazon.com/about-aws/whats-new/2020/12/amazon-s3-replication-adds-support-two-way-replication/).

# 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

        int result = BigIntegerMath.log2(x, mode);
        assertTrue(ZERO.setBit(result).compareTo(x) >= 0);
        assertTrue(result == 0 || ZERO.setBit(result - 1).compareTo(x) < 0);
      }
    }
  }

  // Relies on the correctness of isPowerOfTwo(BigInteger).
  public void testLog2Exact() {
    for (BigInteger x : POSITIVE_BIGINTEGER_CANDIDATES) {
      // We only expect an exception if x was not a power of 2.

	objInfo.ReplicationStatus = fi.ReplicationStatus()
	if objInfo.ReplicationStatus.Empty() { // overlay x-amx-replication-status if present for replicas
		if st, ok := fi.Metadata[xhttp.AmzBucketReplicationStatus]; ok && st == string(replication.Replica) {
			objInfo.ReplicationStatus = replication.StatusType(st)
		}
	}
