Answer: Use AWS Backup to copy EC2 backups and RDS backups to the separate Region.

## Explanation **Correct Answer: A** AWS Backup is a fully managed backup service that makes it easy to centralize and automate the backup of data across AWS services in the AWS Cloud and on premises. It provides: 1. **Single service for multiple AWS services** - AWS Backup supports EC2 instances, EBS volumes, RDS databases, DynamoDB tables, EFS file systems, and more 2. **Cross-region backup copy** - You can easily configure backup copies to be automatically replicated to another AWS Region 3. **Least operational overhead** - AWS Backup handles all the underlying processes automatically, including: - Scheduling backups - Managing retention policies - Copying backups to another Region - Monitoring backup jobs **Why other options are not optimal:** **B. Amazon DLM** - While DLM can automate EBS snapshot creation and management, it only works for EBS volumes and EC2 instances. It doesn't natively support RDS database backups or cross-region copying of RDS backups. **C. AMIs and RDS read replicas** - This approach has significant operational overhead: - Creating AMIs requires manual or scripted processes - Copying AMIs across regions is manual - RDS read replicas are for read scaling, not backup purposes - Read replicas don't provide point-in-time recovery capabilities **D. Manual EBS snapshots + RDS snapshots + S3 CRR** - This involves multiple manual steps: - Creating EBS snapshots - Copying them to another region - Creating RDS snapshots - Exporting RDS snapshots to S3 - Configuring S3 Cross-Region Replication - Managing all these processes separately **Key Benefits of AWS Backup:** - **Centralized management** - Single console for all backups - **Policy-based automation** - Define backup policies once and apply to multiple resources - **Cross-region backup** - Built-in capability to copy backups to another region - **Compliance and monitoring** - Built-in reporting and compliance tools - **Cost optimization** - Can help optimize storage costs with lifecycle policies For a company wanting to back up both EC2 instances and RDS databases to a separate region with the least operational overhead, AWS Backup is the most appropriate solution as it provides a unified, automated approach for both services.
