Use PutBucketReplication with an AWS SDK or CLI

To configure replication for an S3 bucket

The following put-bucket-replication example applies a replication configuration to the specified S3 bucket.

aws s3api put-bucket-replication \
    --bucket amzn-s3-demo-bucket1 \
    --replication-configuration file://replication.json

Contents of replication.json:

{
    "Role": "arn:aws:iam::123456789012:role/s3-replication-role",
    "Rules": [
        {
            "Status": "Enabled",
            "Priority": 1,
            "DeleteMarkerReplication": { "Status": "Disabled" },
            "Filter" : { "Prefix": ""},
            "Destination": {
                "Bucket": "arn:aws:s3:::amzn-s3-demo-bucket2"
            }
        }
    ]
}

The destination bucket must have versioning enabled. The specified role must have permission to write to the destination bucket and have a trust relationship that allows Amazon S3 to assume the role.

Example role permission policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetReplicationConfiguration",
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::amzn-s3-demo-bucket1"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObjectVersion",
                "s3:GetObjectVersionAcl",
                "s3:GetObjectVersionTagging"
            ],
            "Resource": [
                "arn:aws:s3:::amzn-s3-demo-bucket1/*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:ReplicateObject",
                "s3:ReplicateDelete",
                "s3:ReplicateTags"
            ],
            "Resource": "arn:aws:s3:::amzn-s3-demo-bucket2/*"
        }
    ]
}

Example trust relationship policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "s3.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}

This command produces no output.

Example 1: This example sets a replication configuration with a single rule enabling replication to the 'exampletargetbucket' bucket any new objects created with the key name prefix "TaxDocs" in the bucket 'examplebucket'.

$rule1 = New-Object Amazon.S3.Model.ReplicationRule
$rule1.ID = "Rule-1"
$rule1.Status = "Enabled"
$rule1.Prefix = "TaxDocs"
$rule1.Destination = @{ BucketArn = "arn:aws:s3:::amzn-s3-demo-destination-bucket" }
    
$params = @{
    BucketName = "amzn-s3-demo-bucket"
    Configuration_Role = "arn:aws:iam::35667example:role/CrossRegionReplicationRoleForS3"
    Configuration_Rule = $rule1
}

Example 2: This example sets a replication configuration with multiple rules enabling replication to the 'exampletargetbucket' bucket any new objects created with either the key name prefix "TaxDocs" or "OtherDocs". The key prefixes must not overlap.

$rule1 = New-Object Amazon.S3.Model.ReplicationRule
$rule1.ID = "Rule-1"
$rule1.Status = "Enabled"
$rule1.Prefix = "TaxDocs"
$rule1.Destination = @{ BucketArn = "arn:aws:s3:::amzn-s3-demo-destination-bucket" }
