Snapshots capture the state of the volume at a point in time, and regular scheduling (e.g., every hour) ensures data loss is limited to the snapshot interval. The WGU Cloud Deployment and Operations Study Guide (Section 7.3, EBS and Snapshots) states, "Automated EBS snapshots can be scheduled using CloudWatch Events rules to create backups at defined intervals, ensuring an RPO of one hour by capturing volume data regularly."
