Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 456 discussion

Using AWS Backup, you can create backup plans that automate the backup process for your EC2 instances. By configuring cross-Region backup, you can ensure that backups are replicated to the second Region, providing a disaster recovery capability. This solution is cost-effective as it leverages AWS Backup's built-in features and eliminates the need for manual snapshot management or deploying and managing additional EC2 instances in the second Region.

We have implemented solution similar to B, it's really small and simple script, so we don't have much manual work here, and it's really the most cost-effective.

Option B (EBS snapshots with cross-Region copy) is the most cost-effective solution for backing up EC2 instances to a second Region while allowing for centralized management and easy recovery when needed.

The answer is c

How does AWS Backup address that "The company also wants to provision EC2 resources in the second Region"?

C is the most cost-effective solution that meets all the requirements. AWS Backup provides automated backups across Regions for EC2 instances. This handles the backup requirement. AWS Backup is more cost-effective for cross-Region EC2 backups than using EBS snapshots manually or DataSync.
