Which solution meets these requirements?
Configure a policy in Amazon Data Lifecycle Manager (Amazon DLM) to run once daily to copy the EBS snapshots to the additional Regions.
Use Amazon EventBridge (Amazon CloudWatch Events) to schedule an AWS Lambda function to copy the EBS snapshots to the additional Regions.
Set up AWS Backup to create the EBS snapshots. Configure Amazon S3 cross-Region replication to copy the EBS snapshots to the additional Regions.
Schedule Amazon EC2 Image Builder to run once daily to create an AMI and copy the AMI to the additional Regions.
Explanations:
Amazon Data Lifecycle Manager (DLM) can be configured to automate snapshot management and can include the ability to copy snapshots to other regions. DLM policies can be set to copy snapshots to additional regions with minimal operational overhead.
Using Amazon EventBridge and AWS Lambda to copy EBS snapshots would require custom coding and complex setup, leading to higher operational overhead. It does not meet the requirement for the lowest operational overhead.
AWS Backup can create snapshots, but Amazon S3 cross-Region replication is not directly applicable to EBS snapshots. EBS snapshots are not stored in S3 by default, so this solution is not feasible for copying EBS snapshots across regions.
Amazon EC2 Image Builder creates AMIs, not EBS snapshots. Copying AMIs to additional regions may not meet the requirement to specifically copy EBS snapshots, which are distinct from AMIs. It also adds unnecessary complexity.
As far as I’m aware, the answer is:
Configure a policy in Amazon Data Lifecycle Manager (Amazon DLM) to run once daily to copy the EBS snapshots to the additional Regions.
