Disaster Recovery Runbook

A Disaster Recovery Runbook is a detailed guide that outlines the necessary steps to take in the event of a disaster. Here's an example of what a Disaster Recovery Runbook might look like:

  1. Define the disaster and activate the DR Plan:

  • Define the specific disaster that has occurred and activate the DR Plan.
  • Notify the incident management team, stakeholders, and relevant personnel.

2. Assess the Situation:

  • Determine the extent of the disaster and the impact on the application and its infrastructure.
  • Assess the status of backups and replication.

3. Implement Failover:

  • Initiate the failover procedure to the secondary site.
  • Update DNS to redirect traffic to the secondary site.
  • Monitor the status of the application and its components to ensure that the failover is successful.

4. Restore Data:

  • Restore the most recent backup to the secondary site.
  • Verify the integrity and consistency of the data.

5. Verify Application Availability:

  • Test the application on the secondary site to ensure it is available.
  • Monitor the application's performance and logs for any issues.

6. Investigate Root Cause:

  • Investigate the root cause of the disaster.
  • Review logs and other data to determine the root cause.

7. Return to Normal Operations:

  • Determine when to return to normal operations.
  • Update DNS to redirect traffic back to the primary site.
  • Monitor the application's performance and logs to ensure that everything is working as expected.

8. Conduct Post-mortem:

  • Conduct a post-mortem analysis of the disaster and recovery process.
  • Document lessons learned and areas for improvement in the DR Plan.
  • Schedule follow-up tasks to ensure that improvements are implemented.

By following this runbook, you can help ensure that your application can be quickly restored in case of a disaster, and that your business operations can continue with minimal disruption.

Shouldn't the data restoration happen before you do DNS switch over etc.. ?
