Restore testing validation

Set up validation workflow

You can set up a validation workflow using Lambda or any other target supported by EventBridge. For example, if you are validating a restore test containing an Amazon EC2 instance, you may include code that pings a healthcheck endpoint.

You can use the details in the event to determine which resource(s) to validate.

You can use a custom Lambda layer to use the latest SDK (since PutRestoreValidationResult is not yet available via Lambda SDK).

Here is a sample:

import { Backup } from "@aws-sdk/client-backup";

export const handler = async (event) => {
  console.log("Handling event: ", event);

  const restoreTestingPlanArn = event.detail.restoreTestingPlanArn;
  const resourceType = event.detail.resourceType;
  const createdResourceArn = event.detail.createdResourceArn;

  // TODO: Validate the resource
  
  const backup = new Backup();
  const response = await backup.putRestoreValidationResult({
    RestoreJobId: event.detail.restoreJobId,
    ValidationStatus: "SUCCESSFUL", // TODO
    ValidationStatusMessage: "" // TODO
  });
  
  console.log("PutRestoreValidationResult: ", response);
  console.log("Finished");
};

Add an EventBridge rule

Create an EventBridge rule that listens for the restore job COMPLETED event.

Optionally, you can filter events by resource type or restore testing plan ARN. Set the target of this rule to invoke the validation workflow you defined in Step 1. Here is an example:

{
  "source":[
    "aws.backup"
  ],
  "detail-type":[
    "Restore Job State Change"
  ],
  "detail":{
    "resourceType":[
      "..."
    ],
    "restoreTestingPlanArn":[
      "..."
    ],
    "status":[
      "COMPLETED"
    ]
  }
}

Let the restore testing plan run and complete

The restore testing plan will run according to the schedule you have configured.

See Create a restore testing plan if you do not yet have one or Update a restore testing plan if you wish to change the settings.

Monitor the results

Once a restore testing plan has run as scheduled, you can check the logs of your validation workflow to ensure it ran correctly.

You can call the API PutRestoreValidationResult to post the results, which will then be viewable in the Amazon Backup console and through Amazon Backup API calls that describe and list restore jobs, such as DescribeRestoreJob or ListRestoreJob.

Once a validation status is set, it cannot be changed.
