Amazon S3 on Outposts now supports S3 Replication on Outposts. This extends S3’s fully managed approach to replication to S3 on Outposts buckets, helping you meet data residency and data redundancy requirements. With local S3 Replication on Outposts, you can create and configure replication rules to automatically replicate your S3 objects to another Outpost, or to another bucket on the same Outpost. During replication, your S3 on Outposts objects are always sent over your local gateway (LGW), and objects do not travel back to the AWS Region. S3 Replication on Outposts provides an easy and flexible way to automatically replicate data within a specific data perimeter to address your data redundancy and compliance requirements.

With S3 Replication on Outposts, you can replicate objects to a single Outpost destination bucket or to multiple destination buckets. The destination buckets can be in different AWS Outposts or within the same Outpost as the source bucket. As with S3 Replication in regions today, you can select to replicate all the items in your bucket, or you can filter to select objects based on prefix, object tags, or a combination of both. S3 Replication on Outposts also provides detailed metrics and notifications to monitor the status of your object replication. You can monitor replication progress by tracking bytes pending, operations pending, and replication latency between your source and destination Outposts buckets using Amazon CloudWatch. You can also set up EventBridge Notifications to receive replication failure notifications to quickly diagnose and correct configuration issues.

Support for S3 Replication on Outposts is now available at no additional cost in all AWS Regions where AWS Outposts racks are available. To get started with replication visit the AWS Management Console, or read our documentation.
