Question

A company has a web application that stores user transactions in an Amazon DynamoDB table. To comply with regulations, the company must retain a copy of user transaction data for 7 years. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

**AWS Backup** is the ideal solution because it satisfies every requirement with minimal operational overhead:

1. **Scheduled backups**: AWS Backup allows you to define **backup plans** with automated schedules (e.g., daily, weekly). No custom code or manual triggers needed.

2. **Retention policies**: You can set a **retention period of 7 years** directly in the backup plan. AWS Backup automatically manages the lifecycle — creating backups on schedule and deleting them after 7 years.

3. **Native DynamoDB integration**: AWS Backup natively supports DynamoDB tables. You simply assign the DynamoDB table as a **resource** in the backup plan.

4. **Fully managed**: AWS Backup is a centralized, fully managed service. There is no Lambda function to maintain, no EventBridge rule to configure, n
