  • API rate limits for snapshot operations

How It Works

Finder Component

  • Identifies old EBS snapshots
  • Checks snapshot dependencies
  • Calculates potential cost savings
  • Verifies snapshot eligibility for deletion

Fixer Component

  • Validates snapshot selection
  • Checks for dependent AMIs or volumes
  • Deletes eligible snapshots
  • Records actions in CloudTrail

Implementation Details

The implementation process involves:

  1. Snapshot Analysis
    • Identify old snapshots
    • Check snapshot age
    • Verify dependencies
  2. Safety Verification
    • Check for AMI dependencies
    • Verify no active volumes
    • Confirm snapshot age threshold
  3. Snapshot Cleanup
    • Delete eligible snapshots
    • Update CloudWatch metrics
    • Log deletion actions

Important Considerations

  • Snapshot dependencies
  • Recovery requirements
  • Regional restrictions
  • API rate limits

Safety and Rollback

Safety Measures

  • Dependency checking
  • Age threshold validation
  • CloudTrail logging
  • Staged implementation

Rollback Process

  • Note: Snapshot deletions cannot be directly rolled back
  • Maintain good snapshot management practices
  • Consider creating archive copies of critical snapshots
