Use GetBucketReplication with an AWS SDK or CLI

The following command retrieves the replication configuration for a bucket named my-bucket:

aws s3api get-bucket-replication --bucket my-bucket

Output:

{
    "ReplicationConfiguration": {
        "Rules": [
            {
                "Status": "Enabled",
                "Prefix": "",
                "Destination": {
                    "Bucket": "arn:aws:s3:::my-bucket-backup",
                    "StorageClass": "STANDARD"
                },
                "ID": "ZmUwNzE4ZmQ4tMjVhOS00MTlkLOGI4NDkzZTIWJjNTUtYTA1"
            }
        ],
        "Role": "arn:aws:iam::123456789012:role/s3-replication-role"
    }
}

Example 1: Returns the replication configuration information set on the bucket named 'mybucket'.
