Website Disaster Recovery Plan
Prepare for the worst: how to ensure your site recovers quickly from any incident
A disaster recovery plan (DRP) is not a theoretical document that gets filed away and forgotten. It is a living, tested and maintained procedure that allows you to restore your website to operational status after a serious incident: hacking, infrastructure failure, catastrophic human error or a natural disaster affecting your data centre.
Companies without a DRP discover the need at the worst possible moment. This guide explains how to design, document and maintain an effective recovery plan, with clear metrics (RTO, RPO), communication protocols and failover procedures.
RTO and RPO: the fundamental metrics
Every recovery plan is built on two key metrics that must be defined before designing any technical solution.
- RTO (Recovery Time Objective): the maximum acceptable time to restore the service. If your RTO is 1 hour, your plan must guarantee that you can be operational within 60 minutes of declaring the incident.
- RPO (Recovery Point Objective): the maximum amount of data you can afford to lose. If your RPO is 1 hour, you need backups at least every hour. An RPO of 0 requires real-time replication.
Disaster scenarios and response
An effective DRP covers specific scenarios, not generic situations. Each scenario should have a documented response procedure with concrete steps, assigned responsible parties and estimated times.
- Hacking or malware: immediate isolation, forensic analysis, restoration from clean backup, vulnerability patching
- Server or hosting failure: activation of backup infrastructure, DNS migration, data verification
- Human error (accidental deletion): granular restoration from backup, integrity verification
- Sustained DDoS attack: activation of WAF/CDN protection, infrastructure scaling, user communication
- Database failure: restoration from DB backup, transactional integrity verification
- Cloud provider failure: failover to alternative region or provider according to multi-cloud plan
Backup infrastructure
Backup infrastructure is the technical component of the DRP. Its complexity and cost depend directly on the defined RTO and RPO. A 4-hour RTO allows restoration from backup; a 15-minute RTO requires automatic failover.
- Cold standby: powered-off infrastructure activated manually. Most economical, RTO of hours.
- Warm standby: powered-on infrastructure with periodically synchronised data. RTO of minutes to 1 hour.
- Hot standby: active real-time replica with automatic failover. RTO of seconds. Highest cost.
- Multi-region cloud: replicas in different availability zones (AWS, GCP, Azure) for geographical resilience.
Recovery plan testing
An untested DRP is a DRP that will probably fail when needed. Regular tests validate that procedures work, that backups are restorable, that timeframes are met and that the team knows what to do.
Schedule drills at least twice a year. Start with tabletop exercises (paper simulation) and progress to real failover tests in test environments. Document results, identify failures and update the plan. Measure actual recovery time and compare it with your target RTO.
Communication protocol
During an incident, communication is as important as the technical resolution. Users, clients, internal team members and stakeholders need clear, timely and honest information about what happened, what the impact is and when resolution is expected.
- Status page: use Better Uptime, Statuspage or similar to communicate incidents in real time
- Communication templates: prepare predefined messages for different severity levels
- Escalation chain: define who contacts whom and in what order (technical → manager → leadership → external communications)
- Public post-mortem: after resolution, communicate what happened and what measures are being taken to prevent recurrence
DRP documentation
DRP documentation must be accessible, up to date and understandable by everyone involved — not just the technical team. A 50-page document that nobody reads is not a functional DRP.
Structure the document with clear sections: emergency contacts, step-by-step procedures for each scenario, backup infrastructure access credentials (stored securely), architecture diagrams and a post-restoration verification checklist. Review and update the DRP at least quarterly or after each significant infrastructure change.
Continuous plan improvement
Every real incident and every drill is an opportunity to improve the DRP. Blameless post-mortems identify systemic failures that are corrected through changes in processes, tools or architecture.
Record metrics from each incident: detection time, response time, resolution time, data lost and estimated cost. These metrics feed continuous plan improvement and justify investments in more robust backup infrastructure.
Key Takeaways
- Define RTO and RPO based on the real impact of downtime on your business
- Document specific procedures for each disaster scenario, not generic responses
- Backup infrastructure (cold, warm, hot) must align with your RTO objectives
- Test the DRP at least twice a year with real drills
- Communication during an incident is as important as the technical resolution
