Replicating objects for S3 on Outposts

With S3 Replication on AWS Outposts, you can configure Amazon S3 on Outposts to automatically replicate S3 objects across different Outposts, or between buckets on the same Outpost. You can use S3 Replication on Outposts to maintain multiple replicas of your data in the same or different Outposts, or across different accounts, to help meet data-residency needs. S3 Replication on Outposts helps power your compliant storage needs and data sharing across accounts. If you need to ensure that your replicas are identical to the source data, you can use S3 Replication on Outposts to make replicas of your objects that retain all metadata, such as the original object creation time, tags, and version IDs.

S3 Replication on Outposts also provides detailed metrics and notifications to monitor the status of object replication between buckets. You can use Amazon CloudWatch to monitor replication progress by tracking bytes pending replication, operations pending replication, and replication latency between your source and destination buckets. To quickly diagnose and correct configuration issues, you can also set up Amazon EventBridge to receive notifications about replication object failures. To learn more, see Managing your replication.

S3 on Outposts stores a replication configuration as XML. In the replication configuration XML file, you specify an AWS Identity and Access Management (IAM) role and one or more rules.

<ReplicationConfiguration>
    <Role>IAM-role-ARN</Role>
    <Rule>
        ...
    </Rule>
    <Rule>
         ... 
    </Rule>
     ...
</ReplicationConfiguration>

S3 on Outposts can't replicate objects without your permission. You grant S3 on Outposts permissions with the IAM role that you specify in the replication configuration. S3 on Outposts assumes that IAM role to replicate objects on your behalf. You must grant the required permissions to the IAM role before starting replication. For more information about these permissions for S3 on Outposts, see Creating an IAM role.

You add one rule in a replication configuration in the following scenarios:

• You want to replicate all objects.

• You want to replicate one subset of objects. You identify the object subset by adding a filter in the rule. In the filter, you specify an object key prefix, tags, or a combination of both, to identify the subset of objects that the rule applies to.

You add multiple rules in a replication configuration if you want to replicate different subsets of objects. In each rule, you specify a filter that selects a different subset of objects. For example, you might choose to replicate objects that have either tax/ or document/ key prefixes. To do this, you add two rules, one that specifies the tax/ key prefix filter and another that specifies the document/ key prefix.

For more information about S3 on Outposts replication configuration and replication rules, see ReplicationConfiguration in the Amazon Simple Storage Service API Reference.

Replication requires the following:

• The destination Outpost CIDR range must be associated in your source Outpost subnet table. For more information, see Prerequisites for creating replication rules.

• Both the source and destination buckets must have S3 Versioning enabled. For more information about versioning, see Managing S3 Versioning for your S3 on Outposts bucket.

• Amazon S3 on Outposts must have permission to replicate objects from the source bucket to the destination bucket on your behalf. That means you must create a service role to delegate GET and PUT permissions to S3 on Outposts.

  1. Before creating the service role, you must have GET permission on the source bucket and PUT permission on the destination bucket.

  2. To create the service role to delegate permissions to S3 on Outposts, you must first configure permissions to allow an IAM entity (a user or role) to perform the iam:CreateRole and iam:PassRole actions. Then, you allow the IAM entity to create a service role. To make S3 on Outposts assume the service role on your behalf and delegate GET and PUT permissions to S3 on Outposts, you must assign the necessary trust and permissions policies to the role. For more information about these permissions for S3 on Outposts, see Creating an IAM role. For more information about creating a service role, see Creating a service role.

By default, S3 on Outposts replicates the following:

If you delete an object from the source bucket, the following actions occur by default:

• If you make a DELETE request without specifying an object version ID, S3 on Outposts adds a delete marker. S3 on Outposts deals with the delete marker as follows:

  • S3 on Outposts does not replicate the delete marker by default.

  • However, you can add delete marker replication to non-tag-based rules. For more information about how to enable delete marker replication in your replication configuration, see Using the S3 console.

• If you specify an object version ID to delete in a DELETE request, S3 on Outposts permanently deletes that object version in the source bucket. However, it doesn't replicate the deletion in the destination buckets. In other words, it doesn't delete the same object version from the destination buckets. This behavior protects data from malicious deletions.

By default, S3 on Outposts doesn't replicate the following:

• Objects in the source bucket that are replicas that were created by another replication rule. For example, suppose you configure replication where bucket A is the source and bucket B is the destination. Now suppose that you add another replication configuration where bucket B is the source and bucket C is the destination. In this case, objects in bucket B that are replicas of objects in bucket A are not replicated to bucket C.

• Objects in the source bucket that have already been replicated to a different destination. For example, if you change the destination bucket in an existing replication configuration, S3 on Outposts won't replicate the objects again.

• Objects that are created with server-side encryption with customer-provided encryption keys (SSE-C).

• Updates to bucket-level subresources.

  For example, if you change the lifecycle configuration or add a notification configuration to your source bucket, these changes are not applied to the destination bucket. This feature makes it possible to have different configurations on the source and destination buckets.

• Actions performed by lifecycle configuration.

  For example, if you enable a lifecycle configuration only on your source bucket and configure expiration actions, S3 on Outposts creates delete markers for expired objects in the source bucket but doesn't replicate those markers to the destination buckets. If you want the same lifecycle configuration applied to both the source and destination buckets, enable the same lifecycle configuration on both. For more information about lifecycle configuration, see Creating and managing a lifecycle configuration for your Amazon S3 on Outposts bucket.

The following S3 Replication features are currently not supported by S3 on Outposts:

• S3 Replication Time Control (S3 RTC). S3 RTC is not supported because the object traffic in S3 Replication on Outposts travels over your on-premises network (the local gateway). For more information about local gateways, see Working with the local gateway in the AWS Outposts User Guide.

• S3 Replication for Batch Operations.
