Question 12 of 105 | ← Chapter 4

Q207. A company's infrastructure consists of Amazon EC2 instances and an Amazon RDS DB instance in a single AWS Region. The company wants to back up its data in a separate Region. Which solution will meet these requirements with the LEAST operational overhead?

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

Explanation

Option B suggests using Amazon Data Lifecycle Manager (Amazon DLM) to copy EC2 backups and RDS backups to the separate Region. While this approach can work, it may require additional configuration management compared to using AWS Backup, which is designed specifically for backup and restore operations. Option C suggests creating Amazon Machine Images (AMIs) of the EC2 instances and copying the AMIs to the separate Region. While this approach can work, it does not provide a backup solution for the RDS DB instance, and restoring from an AMI may take longer than restoring from a backup. Option D suggests creating Amazon Elastic Block Store (Amazon EBS) snapshots, copying the EBS snapshots to the separate Region, creating RDS snapshots, exporting the RDS snapshots to Amazon S3, and configuring S3 Cross-Region Replication (CRR) to the separate Region. While this approach can work, it requires more manual setup and management compared to using AWS Backup. By using AWS Backup to copy EC2 backups and RDS backups to the separate Region, the company can easily implement an automated backup and restore solution while minimizing operational overhead. This solution provides a cost-effective way to implement disaster recovery for the company's infrastructure in case of data loss in the primary Region. AWS Backup allows for centralized backup management and provides flexible backup schedules and retention policies. This solution meets the requirements stated in the question while minimizing operational overhead.
