Explanation
AWS Backup can take EBS snapshots on a schedule as frequently as every hour, meeting the 60-minute RPO. Backups are stored in the same region, and in the event of a failover, the snapshots can be quickly restored to an EBS volume in another Availability Zone (us-east-1b) without requiring application refactoring.
