A company runs an application on 20 persistent Linux EC2 instances that store data on multiple attached EBS volumes. The company must keep backups in a separate AWS Region and be able to recover instances and configurations within 1 business day, losing no more than one day of data. The company has limited staff and already has a CloudFormation template that can deploy the required network in the secondary Region. Which backup and recovery solution meets these requirements while minimizing operational overhead and cost?

AWS Backup is the most suitable solution because it centrally manages backups for EC2 instances and their attached EBS volumes, including cross-Region replication, which directly addresses the requirement for backups in a separate AWS Region. It also supports restoring entire instances, simplifying recovery and minimizing operational overhead. The 1-day RTO and 1-day RPO are met by daily backups and the ability to restore. Incorrect options: Creating a second CloudFormation template and using Systems Manager for snapshots is more complex and requires manual orchestration for cross-Region copy and restoration, increasing operational overhead. Amazon DLM only manages EBS snapshots, not full instance backups, and doesn't inherently handle cross-Region copy or full instance recovery, making the recovery process more involved. Deploying equivalent instances and using DataSync for data copy is inefficient for persistent EC2 instances with attached EBS volumes, as DataSync is primarily for file system or object storage synchronization, not for backing up and restoring entire EC2 instances and their configurations.
