Answer: AWS Backup

## Explanation **AWS Backup** is the correct answer because: - AWS Backup is a fully managed backup service that makes it easy to centralize and automate the backup of data across AWS services - It supports EC2 instances and EFS file systems natively - Provides centralized backup management with minimal operational overhead - Allows scheduling automated backups and managing backup policies in one place **Why other options are incorrect:** - **AWS Config**: This service is for tracking resource configuration changes and compliance, not for data backup - **Amazon Inspector**: This is a security vulnerability assessment service, not for backup management - **Amazon S3**: While S3 can store backup data, it doesn't provide the centralized backup management, scheduling, and automation capabilities that AWS Backup offers AWS Backup provides the least operational effort because it's a fully managed service that handles the complexity of backup orchestration, retention management, and cross-service backup coordination automatically.
