A company has an application in the AWS Cloud. The application runs on a fleet of 20 Amazon EC2 instances. The EC2 instances are persistent and store data on multiple attached Amazon Elastic Block Store (Amazon EBS) volumes. The company must maintain backups in a separate AWS Region. The company must be able to recover the EC2 instances and their configuration within 1 business day, with loss of no more than 1 day's worth of data. The company has limited staff and needs a backup solution that optimizes operational efficiency and cost. The company already has created an AWS CloudFormation template that can deploy the required network configuration in a secondary Region. Which solution will meet these requirements?

Meets RPO 1 day: Daily AWS Backup + cross-Region copy to a DR vault. Meets RTO 1 business day: Guided EC2 instance & multi-volume restore workflow. Least ops & cost: Centralized policies, lifecycle/retention, no extra runbooks or standing compute. Why not A/B/D: A = more DIY ops; B = DLM can’t restore instances; D = wrong tool (DataSync) + higher cost

AWS Backup can back up EC2 instances and all attached EBS volumes in a single plan, including full configuration, and automatically copy these backups to a target Region with its cross-Region backup copy feature. This provides operational simplicity by managing all backup and copy processes without the need for additional scripts or automation runbooks. In the event of a failure, the network can be set up in the target Region using CloudFormation, and both volumes and instance configurations can be restored from the AWS Backup vault to quickly bring the system online.

With these RTO/RPO WE don't need to backup entire EC2 especially for cost efficiency. We Only need to maintain CF In another region as well as EBS Backups. System Manager allows you to script and execute backup and copy it to another region instead of DL
