WEB RESILIENCE / RECOVERY
Technical Website Hosting Resilience & Backup Guide
Design recovery for engineering websites and technical web applications around source control, configuration, data, DNS, certificates, backup isolation and tested restoration rather than assuming the hosting platform is the backup.
Identify what must be recoverable
- Separate source code, build configuration, environment settings, databases, uploaded files, DNS records and certificates because each may have a different recovery path.
- Define recovery-time and recovery-point objectives from business impact rather than using one generic backup frequency.
- Record third-party dependencies and credentials needed to redeploy the service from a clean environment.
Build independent recovery paths
- Keep source and infrastructure configuration in controlled versioned repositories where practical.
- Maintain backups in a location and failure domain appropriate to the risk; do not assume a provider snapshot covers every application component.
- Protect backup access and recovery credentials so compromise of the production account does not automatically compromise every recovery copy.
Test restoration
- Perform periodic recovery tests into an isolated environment and record actual restore time and missing dependencies.
- Include DNS, certificates, secrets, data integrity and external service connections in the recovery test, not just application files.
- Update recovery documentation after platform, framework or architecture changes.
