Automate root cause analysis for AWS Backup failures with AWS DevOps Agent

This article explains how to use AWS DevOps Agent to automatically diagnose AWS Backup failures across multi-account organizations, eliminating manual triage that can take hours.

• AWS DevOps Agent autonomously investigates backup failures by correlating signals across CloudTrail, IAM policies, KMS key policies, and resource state
• Deploy agent in delegated administrator account with cross-account IAM roles for read-only access to workload accounts
• EventBridge rules forward FAILED, ABORTED, or EXPIRED backup events to central event bus, triggering Lambda function that invokes agent webhook
• Agent posts root cause analysis and remediation recommendations to Slack channel for backup administrators
• Solution extends across multiple AWS accounts and regions using CloudFormation StackSets for consistent deployment
• Agent provides prevention recommendations to stop recurring failures and improve operational posture

Automating backup failure diagnosis reduces investigation time from hours to minutes, narrowing exposure windows and enabling teams to focus on remediation rather than diagnosis.
