Shinken Restore Testing Checklist
Introduction to Restore Testing
Restore testing is an essential part of any disaster recovery plan, and Shinken provides a robust framework for testing and validating backups. In this section, we will outline a comprehensive checklist for Shinken restore testing, including best practices for hardening, monitoring, and reliable restores.
RTO Considerations
Recovery Time Objective (RTO) is a critical metric for measuring the time it takes to restore a system or service after a disaster. Shinken provides features like air-gapped backups and encryption to ensure that data is protected and can be restored quickly in the event of a disaster.
Air-Gapped Backups
Air-gapped backups involve storing backups on a separate network or device that is not connected to the production environment. This provides an additional layer of security and ensures that backups are not compromised in the event of a disaster.
Encryption
Shinken supports encryption for backups, which ensures that data is protected from unauthorized access. This is particularly important for sensitive data, such as financial information or personal identifiable information.
