In this article,we will see
- Create two S3 Buckets inside two different regions
- Enable CRR in Source Bucket.
- Put some content in the source bucket.
- Verify Content in destination bucket(can see the same content).
Cross Region Replication
Cross-region replication is a new feature
It replicates data from one region to another region automatically.
Cross-region replication can be used to back up your data in another region.
It provides asynchronous copying of objects across buckets in different regions.
Once enabled, every object uploaded to a particular S3 bucket is automatically replicated to a designated
destination bucket located in a different AWS region.
For doing CRR (Cross Region Replication), we have to follow below steps.
- Create 2 buckets (Source bucket, Destination bucket)
- Regions must be unique
- Source Bucket – ktexpertsbucket (Mumbai)
- Destination Bucket – micronetexpertsbucket (Singapore)
- Enabled Versioning – Versioning must be enabled on both the source and destination buckets.
First, we need to sign in AWS Console page by using below link.
https://aws.amazon.com/console/
Click on sign in to Console button.
Logging to aws account
