A company hosts a Microsoft SQL Server database on Amazon EC2 instances with attached Amazon EBS volumes. The operations team takes daily snapshots of these EBS volumes as backups. However, a recent incident occurred in which an automated script designed to clean up expired snapshots accidentally deleted all available snapshots, leading to potential data loss. The company wants to improve the backup strategy to avoid permanent data loss while still ensuring that old snapshots are eventually removed to optimize cost. A solutions architect needs to implement a mechanism that prevents immediate and irreversible deletion of snapshots. Which solution will best meet these requirements with the least development effort?
