Here's a step-by-step procedure for configuring S3 Cross-Region Replication (CRR):
1. Create the source and destination S3 buckets:
- Log in to the AWS Management Console.
- Navigate to the S3 service.
- Create the source bucket that contains the objects you want to replicate.
- Create the destination bucket where the replicated objects will be stored.
2. Enable versioning:
- Select the source bucket and go to the "Properties" tab.
- Enable versioning for the bucket.
- Versioning allows S3 to track multiple versions of each object, which is required for replication.
3. Create an IAM role:
- Go to the IAM service in the AWS Management Console.
- Create a new IAM role with the necessary permissions for S3 replication.
- Assign the "AmazonS3ReplicationRole" policy to the role.
4. Configure the source bucket replication:
- Select the source bucket and go to the "Management" tab.
- Click on "Replication" and then "Add rule".
- Choose the source and destination buckets for replication.
- Specify the IAM role created in step 3 as the replication role.
- Configure replication options like replication time control, storage class, and encryption settings.
5. Set up the replication rule:
- Define the replication rule for the source bucket.
- You can choose to replicate all objects or filter based on specific prefixes, tags, or metadata.
- Select the destination bucket and set the storage class for replicated objects.
- You can choose to replicate all objects or filter based on specific prefixes, tags, or metadata.
- Select the destination bucket and set the storage class for replicated objects.
6. Review and confirm:
- Review the replication settings and ensure they are correct.
- Confirm the configuration to enable cross-region replication.
7.Monitor the replication process:
- After enabling replication, monitor the S3 replication metrics and events in the AWS Management
Console.
- You can track the replication progress, view any replication failures, and ensure objects are being replicated as expected.
With these steps, you can configure S3 Cross-Region Replication to automatically replicate objects from a source bucket to a destination bucket in a different AWS region. It provides redundancy, data protection, and enables disaster recovery by keeping copies of your data in multiple regions.
