Disaster Recovery Planning for Technology Companies: A Practical Framework

Disaster recovery is not about preventing bad things from happening — it is about surviving them when they do. And they will. Servers fail, databases corrupt, ransomware encrypts, employees make mistakes, and natural disasters destroy physical infrastructure. The question is not whether you will face a disaster, but whether you will be ready when it arrives.

A disaster recovery (DR) plan documents exactly what to do when things go wrong — who does what, in what order, with what tools, to restore your systems to operational status. The difference between a company that recovers in hours and one that recovers in weeks (or never) is almost always the existence and quality of a DR plan.

Defining Your Recovery Objectives

Before building a plan, define two critical metrics. Recovery Time Objective (RTO) is the maximum acceptable downtime. How long can your business survive without each system? Your public website might tolerate 4 hours of downtime, but your payment processing system might have an RTO of 15 minutes. Recovery Point Objective (RPO) is the maximum acceptable data loss. How much data can you afford to lose? If your RPO is 1 hour, you need backups at least every hour. If it is zero, you need synchronous replication.

These metrics drive every other decision in your DR plan. A 15-minute RTO requires hot standby systems ready to take over instantly. A 24-hour RTO allows for manual restoration from backups. A zero RPO requires synchronous data replication to a secondary site. A 24-hour RPO allows daily backups. Align your investment in disaster recovery with the actual business impact of downtime and data loss.

Risk Assessment: What Can Go Wrong

Catalog every type of disaster that could affect your business and assess the likelihood and impact of each. Hardware failure is the most common — hard drives fail, servers die, network equipment breaks. The impact is usually limited to the affected component. Human error includes accidental deletion, bad deployments, and misconfiguration. It is surprisingly common and often harder to recover from than hardware failure because the damage can be subtle. Cyber attacks including ransomware, data breaches, and DDoS can affect entire systems simultaneously. Natural disasters — fires, floods, earthquakes, power outages — can destroy an entire facility. Software failures including bugs, corrupted data, and failed updates can silently damage data before anyone notices.

Building Your Recovery Strategy

For each critical system, define how it will be recovered. Database recovery uses the backup and restore procedures appropriate for your database. Application recovery involves redeploying from your container registry or infrastructure as code. DNS failover automatically redirects traffic to a healthy system when the primary fails. Communication defines how you notify your team, customers, and stakeholders during and after an incident.

Document every step in detail. A DR plan should be usable by anyone on your team, even under stress, even at 3 AM, even if the person who built the system is unavailable. Include exact commands, configuration details, account credentials (stored securely), and verification steps for each procedure.

Testing Your Plan

An untested plan is a guess, not a plan. Conduct three types of tests. Tabletop exercises walk through disaster scenarios verbally with your team. No systems are affected — it is a discussion exercise that identifies gaps in your plan. Partial restoration tests actually restore individual components (restore a database backup, redeploy an application) to verify the procedures work. Full failover tests simulate a complete disaster by switching to your recovery infrastructure. These are the most valuable but also the most disruptive — schedule them quarterly during low-traffic periods.

After each test, document what worked, what failed, and what was unclear. Update the plan immediately based on findings. The goal is not to pass the test — it is to find the gaps while they do not matter so you can fix them before they do.

Communication During a Disaster

Clear communication during a disaster is as important as the technical recovery. Establish a communication chain: who is notified first, who makes decisions, who communicates with customers. Use a communication channel that does not depend on your own infrastructure — if your systems are down, your internal chat and email may be down too. Have backup communication channels ready.

Prepare customer communication templates in advance — status page updates, email notifications, and social media posts. Transparent, timely communication during an outage actually builds trust. Customers understand that outages happen; what damages trust is silence and dishonesty.

Ongoing Maintenance

A DR plan is a living document. Review it quarterly and update it when your infrastructure changes. New services, new team members, new tools, and organizational changes all affect your recovery procedures. Assign ownership of the DR plan to a specific person or team. Without clear ownership, the plan becomes outdated and useless within months.
