Amazon S3 Replication Time Control (S3 RTC) is a new feature of S3 Replication that provides a predictable replication time backed by a Service Level Agreement (SLA). S3 RTC helps customers meet compliance or business requirements for data replication, and provides visibility into the replication process with new Amazon CloudWatch Metrics.

Customers use S3 Replication to replicate billions of objects across buckets to the same or different regions. S3 Replication Time Control is designed to replicate 99.99% of objects within 15 minutes after upload, with the majority of those new objects replicated in seconds. S3 RTC is backed by an SLA with a commitment to replicate 99.9% of objects within 15 minutes during any billing month. S3 RTC also provides S3 Replication metrics (via CloudWatch) that allow customers to monitor the time it takes to complete replication, as well as the total number and size of objects that are pending replication.

Amazon S3 Replication Time Control is available in all commercial AWS Regions, excluding the AWS China (Beijing) Region and the AWS China (Ningxia) Region. S3 RTC can be configured through the S3 Management Console, SDK, or API. For pricing information, please visit the Amazon S3 pricing page. For more information on the S3 Replication Time Control SLA, please visit the S3 RTC SLA page.

To get started, read about Amazon S3 Replication Time Control on the AWS news blog, in the documentation, on the replication web page or in the S3 Replication FAQs.
