How to create a disaster recovery plan

Info · Vol/mo CA ~250 (est) · KD 12 (est) · Backup & Disaster Recovery

To create a disaster recovery plan, inventory your critical systems and data, set recovery objectives (RTO and RPO) for each, design backups that follow the 3-2-1 rule, document step-by-step recovery procedures, assign clear roles, and test the plan regularly. A disaster recovery plan is a written, tested roadmap that tells your team exactly how to restore operations after an outage, ransomware attack, or natural disaster, so recovery becomes a repeatable procedure rather than a panicked scramble.

Step 1: Inventory systems and assess risk

You cannot protect what you have not identified. Begin by cataloguing every critical system, application, and data source your business depends on, then assess what threatens each one.

Your inventory should capture:

• Critical systems: servers, line-of-business applications, databases, email, and cloud services.
• Data locations: where each dataset lives, including on-premises and SaaS platforms like Microsoft 365.
• Dependencies: what each system needs to function, such as network, power, or specific vendors.
• Risks: hardware failure, ransomware, human error, and location-specific threats like flooding or winter outages.

This foundation tells you what matters most and where you are exposed, which drives every later decision. Skipping it leads to plans that protect the wrong things or miss critical dependencies entirely.

Step 2: Set recovery objectives and design backups

With your inventory in hand, assign each critical system a recovery time objective (RTO) and recovery point objective (RPO). These targets define how fast you must recover and how much data loss you can tolerate, and they directly shape your backup design.

Translate objectives into a concrete backup strategy:

• Follow the 3-2-1 rule: three copies, two media types, one off-site.
• Match backup frequency to each system's RPO.
• Use immutable or air-gapped copies to defend against ransomware.
• Encrypt all backups to protect personal information.

Prioritize systems into tiers so the most critical workloads get the fastest, most frequent protection. This step turns abstract goals into the specific schedules, storage, and technologies your recovery will actually depend on.

Step 3: Document procedures and assign roles

A plan only helps if people can follow it under stress. Write clear, step-by-step recovery runbooks for your most likely scenarios, such as a ransomware attack, a server failure, or a full site outage.

Effective documentation includes:

• Recovery steps: exact procedures to restore each critical system, in priority order.
• Roles and responsibilities: who leads recovery, who restores systems, and who communicates with staff and customers.
• Contact lists: key staff, vendors, and your IT provider, stored where they remain accessible during an outage.
• Communication plan: how you will keep employees, clients, and, if required, regulators informed.

For Canadian organizations, include breach-notification steps to meet obligations under PIPEDA and Quebec's Law 25. Store the plan somewhere reachable even if your primary systems are down, such as a secure off-site or cloud location.

Step 4: Test, review, and improve

An untested plan is an assumption, not a guarantee. Testing is the step that separates a plan that works from one that merely exists, and it is the step most often neglected.

Build a testing routine that includes:

• Restore tests at least quarterly to confirm backups are usable.
• Tabletop exercises where the team walks through a scenario together.
• Full failover tests annually to validate your RTO in practice.
• Plan reviews whenever systems, staff, or vendors change.

Each test reveals gaps, such as outdated contacts, broken backup jobs, or recovery times longer than expected, that you can fix before a real emergency. Treat the plan as a living document, updated continuously. A managed IT provider can run these tests, document results, and keep your plan current so it remains reliable as your business evolves.

FAQ

What are the main steps to create a disaster recovery plan?

The core steps are: inventory your critical systems and assess risks, set recovery objectives (RTO and RPO) for each system, design backups following the 3-2-1 rule, document step-by-step recovery procedures, assign clear roles and contacts, and test the plan regularly. Together these turn recovery into a repeatable, documented process rather than an improvised reaction to crisis.

How long does it take to build a disaster recovery plan?

A small business can develop a solid initial plan in a few weeks, covering inventory, recovery objectives, and documented procedures. Larger or regulated organizations may take a few months. The ongoing work of testing and updating never truly ends, since the plan must evolve as your systems, staff, and risks change over time.

What is the difference between a disaster recovery plan and a business continuity plan?

A disaster recovery plan focuses on restoring IT systems and data after an incident, while a business continuity plan is broader, covering how the entire organization keeps operating during a disruption, including staff, facilities, and processes. Disaster recovery is essentially the IT component of the wider business continuity strategy, and the two should be aligned.

How often should a disaster recovery plan be tested?

Test restores at least quarterly and run a full failover exercise annually. Review and update the plan whenever you change important software, infrastructure, or staff. Regular testing uncovers broken backups, outdated contacts, and recovery times that exceed your targets, letting you fix these issues before they cause real damage during an actual emergency.
