Rule: S3 Bucket Cross-Region Replication Should Be Enabled
This rule ensures that S3 bucket cross-region replication is properly configured to prevent data loss.
| Rule | S3 bucket cross-region replication should be enabled |
| Framework | GxP 21 CFR Part 11 |
| Severity | ✔ Critical |
Rule Description
The S3 bucket used for GxP (Good x Practice) compliance, specifically for 21 CFR Part 11, should have cross-region replication enabled. This ensures that data stored in the bucket is automatically replicated to a different region, providing a backup of the data and enabling disaster recovery in case the primary region experiences an outage or other issues.
Troubleshooting Steps
If cross-region replication is not enabled for the S3 bucket, follow these troubleshooting steps:
- 1.
Verify bucket permissions: Check if you have the necessary permissions to enable cross-region replication. Ensure that you have the appropriate IAM (Identity and Access Management) policies assigned.
- 2.
Check bucket versioning: Cross-region replication requires versioning to be enabled on the bucket. Check if versioning is already enabled. If not, enable versioning for the bucket.
- 3.
Validate bucket replication settings: Ensure that the replication configuration for the bucket is correctly set up. Check the replication rules to verify if the source and destination regions are specified correctly.
- 4.
Confirm bucket location constraints: Cross-region replication can only be enabled between regions that support it. Verify that both the source and destination regions support cross-region replication.
- 5.
Review AWS CLI and SDK versions: If you are using AWS CLI (Command Line Interface) or SDK (Software Development Kit), ensure that you have the latest versions installed. Outdated versions may cause compatibility issues with cross-region replication settings.
Code
If you need to enable cross-region replication for an S3 bucket, you can accomplish it using AWS CLI with the following command:
aws s3api put-bucket-replication --bucket <bucket-name> --replication-configuration file://replication-config.json

<bucket-name>replication-config.jsonStep-by-Step Guide for Enabling Cross-Region Replication
- 1.
Open the AWS Management Console and navigate to the S3 service.
- 2.
Locate and select the S3 bucket that requires cross-region replication.
- 3.
Click on the "Properties" tab and scroll down to find the "Replication" section.
- 4.
Ensure that versioning is enabled for the bucket. If not, enable it by clicking on the "Edit" button next to "Versioning" and enable versioning.
- 5.
Click on the "Add rule" button to define a replication rule.
- 6.
In the replication configuration, specify the source and destination regions for replication. You can select the desired destination region from the drop-down menu.
- 7.
Choose the desired replication options, such as replication time control and storage class settings.
- 8.
Click on the "Create rule" button to create the replication rule.
- 9.
Verify the replication configuration by checking the status in the "Replication" section. It should show as "Enabled".
- 10.
Perform a test by uploading a test file to the S3 bucket and confirming that it gets replicated to the designated destination region.
By following these steps, you can enable cross-region replication for an S3 bucket to ensure GxP compliance with 21 CFR Part 11.
