Whether you’re a fintech startup, SaaS company, or a large clinic, you need to keep your IT infrastructure ready for the unexpected. A single data breach can lead to downtime, legal issues, and financial losses – alongside threats like natural disasters and malware.

The good news is that you can prepare in advance. An IT disaster recovery plan helps you maintain control in times when the organization is already under pressure.

Learn how to respond to disruptions with a structured, coordinated approach and quickly restore critical operations. To help you put these steps into practice, we’ve crafted a detailed IT disaster recovery checklist. You can find it below or download a copy to use whenever you need it.

The IT disaster recovery plan is part of the larger organizational resilience framework, which includes business continuity management (BCM), crisis management, and incident response. As part of BCM, it establishes recovery objectives, procedures, responsibilities, priorities, resources, and communication processes needed to restore critical IT systems.

Step 1. Establish scope, governance, and ownership

To begin with, define what your DR plan covers: list all relevant business units, critical IT systems, applications, and production infrastructure. It should include not only internal assets, but also relevant third-party services and providers, as well as the types of disruptions your plan addresses. The challenge is to make the scope broad enough to cover dependencies critical to recovery, without creating a document that attempts to cover every possible failure.

Then, specify what disaster means for your business. Four minutes can be a disaster for a hospital if a critical clinical system becomes unavailable during patient care, but barely noticeable for a consulting firm if an internal system goes offline while employees can continue working.

Here are some criteria you might consider:

severity and expected duration
number or importance of affected services
business impact
data loss or corruption
geographic scope
inability to recover using normal operational procedures
impact on customers or contractual commitments

Next, define roles and responsibilities when the plan is activated (including who has the authority to declare a disaster and activate the plan). It is equally important to distinguish between those involved in recovery and those accountable for it to avoid confusion later.

Even if the major incident happened in the IT department, the recovery process touches many parts of the organization, from executive management to PR and legal teams. Here are the core activities for successful governance and ownership:

Assign ownership of the overall DR program.
Designate a recovery lead for major incidents.
Define the authority to activate the DR plan.
Establish responsibility for recovery-priority decisions.
Assign system owners and owners of individual recovery procedures.
Define responsibility for coordinating with business stakeholders.
Assign responsibility for customer, vendor and external communications.

By this point, you should have a list of assets your plan covers, a definition of what a disaster is for your business, assigned stakeholders and decision-making roles, and an established disaster recovery team.

Step 2. Assess risks and threats

When doing an IT risk assessment, there’s no point in considering earthquakes if your business is in a zone of low seismic activity. Focus on realistic, context-specific scenarios that could genuinely affect the business. The core ones include cyber threats (compromised accounts), technology failures (database corruption), third-party failures (cloud provider outage), physical events (power outage), and human/operational errors (accidental data deletion).

Cloudflare’s November 18, 2025 outage is a great example of how third-party services can become a single point of failure even when your own IT infrastructure remains fully operational. A configuration-related software malfunction disrupted core network traffic and affected services, including its CDN, security services, and authentication.

Once you have your list, ask two simple questions:

How likely is this to happen?
What would happen if it did?

For likelihood, a simple rating is enough for most companies: low, medium, or high. To rank the risks, think about how often each incident has happened in the past and how often it happens in your industry. Is it becoming a trend? For example, banks now face more AI-powered fraud than in years past because AI can make scams more convincing. In contrast, healthcare suffers more from ransomware, data breaches, and phishing.

Then, evaluate how exposed the organization is to the threat. Do you have effective preventive and protective measures, such as MFA, data backups, or network segmentation? What are the points of additional exposure? (This may include diverse digital assets like cloud environments, AI systems, and user accounts). The answers will help you assign the risk rating for each threat and understand the priorities.

Today, AI adoption adds a layer to IT resilience. AI systems can become targets for attackers and malware, making them an important consideration in resilience planning. At the same time, poorly secured models, data, integrations, or supporting infrastructure can introduce new vulnerabilities. An IBM report finds that 97% of companies say that they do not have sufficient AI access management in place. At the same time, 78% of Chief Information Security Officers reported creating dedicated security teams for AI agents.

Going back to the potential consequences, consider things like downtime, data loss, contractual or SLA breaches, regulatory consequences, and reputational damage. Define what systems could be affected and the impact on employees, customers, finances, and compliance.

Step 3. Assess business impact and recovery priorities

The next step in an IT disaster recovery assessment is exploring how a disaster could affect your IT systems, data, and dependencies. Start by defining the core functions of your business, e.g., what cannot be disrupted for long.

If you’re an ecommerce company, the uptime of your online store is critical, as are order and payment processing, inventory control, and shipment management. In this case, issues with payment services directly impact revenue, while disruptions in delivery coordination affect core operations.

Moving further, match each critical business function with the underlying technology. It may include servers, storage, networks, applications, and SaaS services. Such mapping helps you reveal hidden dependencies and set system recovery priorities. At this point, you may find some single points of failure – dependencies with no backup or fallback if they fail.

Finally, decide what must be recovered first. Since this process takes resources, infrastructure, and personnel, not all systems can be restored simultaneously. Some apps and functions can tolerate a longer outage, and some dependencies can wait. Defining the order in which systems should be recovered helps to minimize downtime when something goes wrong.

Step 4. Define RTO, RPO and recovery metrics

Defining recovery time objective (RTO), recovery point objective (RPO), maximum tolerable downtime (MTD), and recovery metrics establishes measurable recovery requirements. You shift from expectations and ambiguity to clear timelines, putting you on firm ground when evaluating recovery performance.

RTO is a target that defines the maximum acceptable time between disruption and full recovery. It highlights the period a service can be unavailable before the impact becomes unacceptable. What stands out is that RTO comes from business requirements, not current capabilities. It may or may not be achievable at the time of planning.

RPO is also a target that benchmarks the maximum amount of data loss you can accept, expressed as a period of time. For a financial services company with an RPO of five minutes for transaction data, this means it should be able to recover to a point no more than five minutes before the incident occurred. It is quite natural for different data types to have different RPOs.

MTD is a business limit that specifies the longest period a business can tolerate a disruption before the impact becomes too severe. It should be longer than RTO to give the business some margin in case complications occur during recovery.

Recovery metrics are the KPIs that determine whether the organization can actually meet the targets. The key indicators include actual recovery time, actual recovery point, recovery test success rate, and recovery test coverage.

Together, these metrics highlight gaps between recovery targets and actual capabilities, supporting decisions on investments and improvements. Moreover, RTO and RPO values help you choose appropriate recovery strategies.

Step 5. Map IT assets, infrastructure, and dependencies

Unlike Step 1, where we defined the plan’s scope, and Step 3, where we mapped business functions to supporting IT services, this step is far more technical.

Start by listing critical IT assets. For example, you identified payment processing as a high-priority business function. Now, go one level deeper and document the technology that supports it:

payment application
databases
application servers
network connections
identity services
cloud environment
external payment providers

Record where each component is hosted, who owns it, what it depends on, and what other services depend on it. After listing all mission-critical applications and their tech, you’ll get a technology map with interconnected systems, infrastructure components, and third-party services. It helps you understand what needs to be available for a service to function and recover successfully. The mapping also highlights the weakest points that otherwise could be overlooked at earlier stages.

Lastly, document ownership and technical details for each critical asset so you can understand, access, recover, and escalate issues with the system. The records typically include business and technical owners, the hosting environment, data location, vendor and support details, recovery documentation, and access requirements. The list can be expanded depending on the change frequency, criticality, ownership, and other factors.

Note: Keep sensitive data, such as credentials and secrets, out of the DR document.

Step 6. Design the recovery strategy

A disaster recovery strategy is the set of measures you should take to restore critical systems. Based on RTO, RPO, business impact, and technical dependencies identified earlier, the strategy typically includes:

choosing recovery methods for critical systems;
selecting the recovery environment;
defining backup and replication strategies;
reducing single points of failure;
planning for third-party failures.

The core idea behind your strategy is to anticipate the loss of one or more system components: the physical environment, hardware, software, data, or connectivity. The right recovery method depends not only on the defined targets but also on system architecture, security, compliance, and resilience requirements. In general, the more demanding the RTO and RPO, the more complex and costly the recovery methods.

Align all recovery activities with your IT service management (ITSM) processes to ensure consistent incident handling. Otherwise, you’ll probably see unclear recovery ownership, incomplete restoration, and repeated failures. Your service can be restored correctly from a technical standpoint but still fail operationally.

For third-party failures, first establish alerting mechanisms for provider outages or security incidents. Then, define vendor-specific escalation paths and procedures when basic vendor support is insufficient. Determine timing and channels for customer and stakeholder notifications. Assess your IT resilience and consider alternative service arrangements in case this is a single provider for your core systems.

Don’t forget to build cybersecurity into the recovery strategy. Safeguard recovery environments, backups, and privileged access from compromise, especially during recovery from ransomware or other cyber threats.

The final and important step is to document the recovery sequence – what should be restored first, what systems rely on it, and how other apps/services should be brought back online. Documentation reduces ambiguity and eliminates different interpretations of the procedures, so when a disaster hits, you’ll have a clear, usable recovery sequence.

Types of disaster recovery strategies

Disaster recovery strategies involve a certain level of implementation complexity, cost, and expected recovery time. The strategy should align with RTO, RPO, business impact, and technical dependencies defined at earlier steps. Each critical service can use one approach or combine several.

Backup and data recovery

As the name suggests, the strategy allows you to back up critical systems/data and restore them after the incident. You can choose it if your business can tolerate relatively long downtime and some data loss, or if the system is important but not time-critical enough to require continuous recovery.

Compared to other strategies, backup and data recovery fit less demanding RTO/RPO requirements. Recovery can take a long time, and speed depends on the amount of data, backup frequency, and the recovery process. While this strategy is least costly and has low to medium complexity, its main limitation is that it does not guarantee fast recovery. The company must also be able to restore its infrastructure, applications, and data within the required RTO.

Pilot light

A pilot light strategy involves maintaining a small, essential version of your production IT environment in another location or in the cloud. You select it when you need a fairly quick recovery but cannot afford the cost of a complete parallel environment. Overall, pilot light is quicker than backup and data recovery, but more complex and costly. It offers a compromise between cost and recovery time.

The strategy fits you if your business can accept a few hours of downtime, you want to control DR costs, or you need a low RPO. Nevertheless, the strategy won’t work well if you need near-immediate recovery, cannot tolerate even a few minutes of downtime, or have very limited IT expertise.

Warm standby

While a pilot light includes a minimal DR environment, warm standby supports more than a foundation – most of the backup environment is already running. Still, warm standby is not a full-scale replica of your production environment: warm standby maintains a minimum deployment that can handle requests, but it cannot handle production-level traffic.

The strategy fits businesses that prioritize fast recovery but can tolerate minutes to a few hours of downtime, require low RPO, and need to balance recovery speed and cost. However, warm standby cannot guarantee immediate recovery, and its DR environment has lower capacity than a production environment. The method is costlier than previous options, has medium to high complexity, and requires regular testing, monitoring, and maintenance.

Active/passive

The strategy implies two operational environments – active and passive. The active environment handles normal business operations. When disaster strikes, the passive environment takes over the workload. It should be sufficiently isolated from the primary environment to avoid being affected by the same failure and may be deployed in a separate region, physical location, or cloud environment.

Yet, passive infrastructure often provides little to no business value during normal operations, but requires ongoing maintenance and related costs. Switching operations take time to switch operations and require regular testing. In addition, if you need to restore data from backup before the passive environment starts, or secondary infrastructure requires additional operations before accepting live traffic, this can increase recovery time. Ensure that these increases remain within acceptable RTO/RPO limits and align with business objectives.

Multi-region active/active

Following this strategy, the business deploys a production environment in multiple locations. Each environment processes workloads and serves users. When a disaster occurs, the workload is redistributed to the unaffected regions with minimal disruption. A multi-region active/active approach provides the highest level of resilience and availability, near-zero downtime, and a very low RPO.

The major limitations are high complexity and cost. The complexity arises from the need to coordinate applications, databases, networking, security, monitoring, and deployments across multiple regions – not to mention ensuring that they work correctly. The core cost drivers come from operating multiple production environments, meaning more infrastructure, licensing, security, testing, and maintenance.

Infrastructure vs. data in disaster recovery scenarios

A business’s technology ecosystem has several interconnected layers: infrastructure (computing, storage, networks, cloud resources), applications (ERP, CRM, ecommerce, payroll), and data. When planning for disaster recovery, consider these layers separately while accounting for their dependencies. Each may have different recovery strategies and RTO requirements, but the recovery sequence is still important because restoring one layer may depend on another being available first.

Disaster recovery matters regardless of what stack you’re running – cloud or on-prem. If you’ve got a single point of failure, eliminate it. And once you’ve built the recovery path, actually test it.

Running a full DR drill is no small effort – it’s genuinely hard to pull off unless you’re fully in the cloud or have spare hardware available to mirror your production environment. But if you’ve put in the work to build a DR plan, it’s worth running through it at least once to make sure it actually holds up.

Backups are a different story: those should be tested regularly, ideally on an automated schedule, because an untested backup is no backup at all.

Step 7. Develop executable recovery runbooks

It’s time to prepare clear instructions for your teams in case of IT disruption. Here, it is vital to find the right balance between coverage and usability. Dozens of runbooks are hard to maintain and navigate. In contrast, a single runbook for all recovery procedures is something nobody can realistically use during an incident.

A good recovery runbook covers a specific recovery procedure or scenario that one or more teams can use. You might have a network recovery runbook, backup restoration runbook, ransomware recovery runbook, etc. It also makes knowledge something the business owns, rather than something held by a single administrator or engineer. After all, recovery runbooks ensure knowledge is not siloed, but is repeatable and transferable.

Core components of a recovery runbook:

Clear steps. Easy, specific instructions for an employee who can follow them confidently without guessing.
Technical procedures. Necessary commands, configurations, scripts, system paths, or other technical details needed for the recovery.
Verification. Explanations of how to ensure that each recovery step worked and that the recovered service runs correctly.
Dependencies. A list of access requirements, credentials, backups, other systems that need to be available or completed before recovery can begin.
Failover/failback. Description of how to switch to the recovery environment and return to the normal environment once the primary service is restored.
Prerequisite information and references. Links to relevant system documentation, diagrams, vendor procedures, or other runbooks to reduce duplication.

Note: You can automate repetitive or error-prone tasks within recovery procedures. However, this creates another dependency, as the automated processes must work when you need them. If you decide to use automation for recovery, your runbook should define its scope and the procedures to follow when it’s unavailable.

Step 8. Establish communication and coordination

A communication and coordination structure helps to keep teams involved and recovery tasks synchronized. It ensures you can make decisions quickly, keep stakeholders informed, and manage recovery activities when time matters most.

A good structure defines how the recovery team communicates during an incident and which channels it uses; how business owners coordinate with IT teams; and how the company reaches out to customers and vendors. To facilitate the process, you can prepare templates for each case. It will speed up communication during stressful situations.

Main Step 8 deliverables include:

Communication channel plan
Business/IT coordination procedures
Emergency contact list
Notification procedures
Communication materials

As contacts tend to change when employees leave or join the company, regularly review communication documents and keep them updated. Make sure to also check vendor and customer contacts. A good idea is to set a review frequency and a responsible person, along with access control to sensitive contact information.

Step 9. Test, measure, and continuously improve

Now it’s time to validate your disaster recovery plan. This step checks whether your employees understand the runbook instructions, can communicate effectively under pressure, and whether your plan works and meets RTO/RPO objectives.

Define what you want to test and how often. Since you often simulate disasters for testing (as cutover tests can cause real interruptions), another important metric is the level of realism. Overall, the testing strategy largely overlaps with what you’ve done at earlier stages: prioritize critical systems and recovery procedures, select relevant disaster scenarios, and test communication and escalation procedures.

When dealing with ransomware or compromised-system scenarios, include security testing in the test list. It will help to verify that services can be restored securely and that the recovery process does not reintroduce the incident.

The key idea behind testing is finding out whether the company can recover the system within the recovery requirements defined by the DR plan and applicable service level objectives (SLOs). If the answer is negative – as the test shows you can recover the critical services in 2.5 hours when your RTO is just 2 hours – consider corrective actions to close the gap.

Finally, don’t forget about timely maintenance. The disaster recovery plan is an evolving resource. After any test, incident, or significant business or technology change, review whether it still reflects the organization’s current needs. Otherwise, you’ll be caught unprepared when disaster strikes.

Summing up

Disaster recovery is a part of a wider framework known as business continuity planning. A solid IT recovery strategy covers realistic risks, maps your critical systems, technology, and dependencies, as well as includes practical steps to restore core services. A practical plan stays accessible in times of failure, ensuring key recovery data is regularly refreshed to reflect business changes.
