S3 buckets update#

If your objects are encrypted with SSE-KMS, you will be charged for two KMS operations (decrypt at source and re-encrypt in destination) at a rate of $0.03 per 10,000 requests (more details on KMS charges here). Since you are replicating data in between two AWS Regions, you will also be charged the data transfer fee of $102.4 (data transfer fee is $0.02/GB). You have 1.3 million objects in the bucket, so you will be charged replication request charges of $6.50 (request charges are $0.0 requests). Your bucket is comprised of 4-MB objects and the data sums up to 5 TB in size. Additionally, when you use S3 Replication Time Control (S3 RTC), you pay a Replication Time Control Data Transfer fee.įor example, let’s assume you want to replicate data from US-west to US-east with CRR. For Cross-Region Replication (CRR), you also pay for inter-Region Data Transfer OUT from S3 to each destination Region. Estimating cost of S3 Replicationįor S3 Replication (Cross-Region Replication and Same-Region Replication), you pay for replication request charges, storage charges for selected destination, and applicable infrequent access storage retrieval fees. To enable S3 Replication, refer to the S3 Replication User Guide. S3 Replication can be used to copy new objects between two or more S3 buckets, and can be additionally enabled to copy existing objects. Buckets configured for object replication can be owned by the same or different AWS accounts and can be in the same or different AWS Regions. S3 Replication enables automatic, asynchronous copying of objects across Amazon S3 buckets.

Section 1: Replicating new objects between S3 buckets Next, we go into more advanced techniques for migrating data, which might be useful if you need to re-drive replication tasks. We start with S3 Replication, a simple-to-configure S3 feature that will replicate all newly written objects, as they are written.

In this post, we walk through the options available to S3 customers for migrating or synchronizing data, and provide guidance on which is the best choice for different scenarios. The need for data synchronization in Amazon S3 comes up in a number of scenarios for customers – enabling a new geographic region for end users, migrating data between AWS accounts, or creating additional copies of data for disaster recovery (DR). See the S3 User Guide for additional details.

UPDATE (): Amazon S3 Batch Replication launched on, allowing you to replicate existing S3 objects and synchronize your S3 buckets.
