Setting Up Automated System Backup

Objective: Set up an automated backup system for the DynamoDB table studentData by modifying the Lambda function BackupDynamoDBAndSendEmail (integrated with the POST /backup endpoint, section 4.8) and creating an Amazon EventBridge Rule to trigger scheduled backups. The backup will save data to the S3 Bucket student-backup-20250706 (section 6.5) and send notification emails via Amazon SES. The system ensures:

  • Automation of the backup process to minimize manual intervention.
  • Integration with the web interface (distributed via CloudFront, sections 7.1–7.3) and the student API (stage prod, section 4.8).
  • Security with StudentApiKey (section 4.2) and IAM role DynamoDBBackupRole (section 6.5).

Prerequisites

You need to complete sections 7.1–7.3 (create and configure CloudFront StudentWebsiteDistribution), 6.1–6.5 (configure S3 Buckets student-management-website-2025 and student-backup-20250706), 5 (build the web interface), 4.1–4.9 (create and deploy the student API, StudentApiKey, StudentUsagePlan, endpoints GET /students, POST /students, POST /backup, CORS, stage prod), 3.3 (create the Lambda function BackupDynamoDBAndSendEmail with the role DynamoDBBackupRole), and 3 (create the DynamoDB table studentData, verify SES email). Ensure your AWS account has permissions for lambda:UpdateFunctionConfiguration, events:PutRule, events:PutTargets, iam:PassRole, and the AWS region is us-east-1.

Configuration Steps

Below are the specific steps to set up automated backup:

Step Content Description
8.1 Modify Lambda Backup Configuration Update the Lambda function BackupDynamoDBAndSendEmail to support triggering from EventBridge, ensuring data from DynamoDB studentData is saved to S3 student-backup-20250706 and email is sent via SES.
8.2 Create EventBridge Rule for Automated Backup Create an Amazon EventBridge Rule StudentDataBackupRule to trigger the Lambda function BackupDynamoDBAndSendEmail on a schedule (e.g., daily).

Note: Follow the steps in order to ensure the automated backup is configured correctly. Each step is detailed in the corresponding documentation.

Conclusion

By completing these configuration steps, you will have:

  • The Lambda function BackupDynamoDBAndSendEmail updated to support both API Gateway and EventBridge triggers.
  • The EventBridge Rule StudentDataBackupRule triggering scheduled backups, saving data from DynamoDB studentData to S3 student-backup-20250706 with SES notifications.
  • A fully integrated system with the student API (stage prod) and the web interface via CloudFront StudentWebsiteDistribution.
