Business Disaster Recovery Plan: An IT Checklist

A business disaster recovery plan explains how critical technology will be restored after a disruptive event. It is narrower than a complete business continuity plan, but it must connect to people, facilities, vendors, communications, and operating priorities. The plan becomes useful when it states what comes back first, who makes decisions, and how recovery is tested.

How do you inventory critical services and dependencies?

List the services required to operate: identity, internet connectivity, phones, email, file storage, business applications, websites, databases, and vendor platforms. For each one, record an owner, technical contact, location, credentials process, data source, and downstream dependencies.

  • Identity and internet connectivity
  • Phones and email
  • File storage and business applications
  • Websites, databases, and vendor platforms

Map dependencies in the order they must be restored. An application recovery can fail even when its server is healthy if identity, DNS, certificates, storage, or network access are unavailable.

How do you set recovery priorities and targets?

A recovery time objective describes the target time to restore a service. A recovery point objective describes the acceptable amount of data loss measured in time. These should follow business impact, not an arbitrary technology standard.

Different systems can have different targets. Assigning the shortest target to everything creates a costly plan that may still lack a meaningful sequence.

How do you design backups for actual restore needs?

Match backup frequency and retention to the recovery-point target. Protect backup administration, keep a recovery path separated from ordinary production credentials, and account for configuration, identity, and encryption keys—not only business files.

Document how data is restored into a usable service. A database dump without the application version, configuration, secrets, or infrastructure needed to run it may not meet the recovery objective.

How do you plan communications and authority?

Name who can declare a disaster, approve emergency spending, contact vendors, communicate with employees and customers, and accept a temporary workaround. Keep an accessible copy of essential contacts outside the systems that may be unavailable.

  • Who can declare a disaster
  • Who can approve emergency spending
  • Who contacts vendors
  • Who communicates with employees and customers
  • Who can accept a temporary workaround

Include alternatives for the loss of a building, power, internet circuit, cloud tenant, administrator, or key supplier. The response will differ by scenario, but the decision structure should remain clear.

How do you test, record gaps, and update the plan?

Run tabletop exercises to validate people and decisions, then perform technical restore tests for critical systems. Measure the result against recovery targets and record missing access, undocumented dependencies, slow transfers, or incompatible backups.

Review the plan after tests and material changes. Nubinity datacenter and professional services can help assess infrastructure dependencies, recovery architecture, connectivity, storage, and operational documentation.

Questions

Common follow-ups.

What is the difference between disaster recovery and business continuity?

Disaster recovery focuses on restoring technology and data. Business continuity covers the broader ability to keep essential business functions operating, including people, facilities, suppliers, and manual workarounds.

How often should a disaster recovery plan be tested?

Test critical recovery procedures on a defined schedule and after material changes. Frequency should reflect business impact, system change rate, contractual requirements, and the cost of an unverified recovery path.

Is a cloud service automatically disaster-proof?

No. Cloud services still have identity, configuration, data, vendor, region, integration, and administrative dependencies. Understand what the provider protects and what remains the customer's responsibility.
