Amazon Simple Storage Service (S3) supports many types of replication, including S3 Same-Region Replication (SRR), which launched in 2019 and S3 Cross-Region Replication (CRR), which has been around since 2015. Today, we are happy to announce S3 Replication support for multiple destination buckets. S3 Replication now gives you the ability to replicate data from one source bucket to multiple destination buckets. With S3 Replication (multi-destination) you can replicate data in the same AWS Regions using S3 SRR or across different AWS Regions by using S3 CRR, or a combination of both.
Before this launch, if you needed to have multiple copies of your data in different S3 buckets, you had to build your own S3 replication service by monitoring S3 events, identifying created objects, and using AWS Lambda functions to copy objects to each destination bucket.
This launch removes the need for you to develop your own solutions to replicate
