Alfred Backup Notifier intends to check the last object date in AWS S3 bucket, and if it's older than today, send alerting email via AWS Simple Email Service (SES).

I'm using this to monitor the effective backup of my home automation system and be alerted on any backup issue.

Technical details

  • Uses AWS Lambda function (Python)
  • Rely on AWS Lambda layer for boto3 and botocore
  • Scheduled Lambda (daily) with CloudWatch Events
  • Uses AWS Simple Email Service (SES) for Emails Notifications



Build layer, and Lambda function package.

$ make layer
$ make package


Deploy CloudFormation stack.

$ make deploy env=<your_env>


Remove unused folders and files after deploying the stack.
