Question
A solutions architect works for a government agency that has strict disaster recovery requirements. All Amazon Elastic Block Store (Amazon EBS) snapshots are required to be saved in at least two additional AWS Regions. The agency also is required to maintain the lowest possible operational overhead. Which solution meets these requirements?

Why each option
To meet strict disaster recovery requirements for EBS snapshots across multiple AWS Regions with the lowest operational overhead, configure AWS Backup to create snapshots and natively manage their cross-Region replication.
Amazon Data Lifecycle Manager (DLM) can manage EBS snapshots and cross-Region copies, but AWS Backup offers a more comprehensive and centralized solution for data protection across multiple AWS services, potentially leading to lower overall operational overhead for an agency with broader DR needs.
Using Amazon EventBridge to schedule an AWS Lambda function for snapshot copying involves custom development and ongoing maintenance, which increases operational overhead compared to a fully managed service like AWS Backup.
AWS Backup provides a centralized, managed service for creating EBS snapshots and includes native capabilities for configuring cross-Region replication within its backup plans. This automates the replication process and reduces operational overhead compared to custom solutions, making it ideal for government agencies with strict compliance needs.
Amazon EC2 Image Builder creates Amazon Machine Images (AMIs), which contain snapshots, but the requirement is specifically for EBS snapshots. This approach is not the most direct or lowest overhead solution for replicating raw EBS snapshots for disaster recovery.
