Quick answer: A solid IT disaster recovery plan should include a risk assessment, a business impact analysis, clear recovery time and recovery point objectives, defined roles and communication protocols, data backup procedures, a tested failover strategy, and a documented testing schedule. Together, these elements help a business restore critical systems quickly and minimize downtime after an outage, cyberattack, or natural disaster.
Downtime is expensive. According to IBM’s Cost of a Data Breach Report, the average cost of a data breach reached $4.45 million in 2023. Beyond the financial hit, prolonged outages damage customer trust and can put a company out of business entirely. Studies from the Federal Emergency Management Agency (FEMA) have long noted that a significant share of small businesses never reopen after a major disaster.
Despite these stakes, many organizations still treat disaster recovery as an afterthought — something to document once and forget. That approach rarely survives contact with a real incident. An effective IT disaster recovery plan (DRP) is a living document, built around specific objectives, tested regularly, and understood by every employee who might need to act on it.
This post breaks down exactly what a business should include in an IT disaster recovery plan, from the initial risk assessment to the final testing schedule, so your organization can bounce back quickly when something goes wrong.
Why does a business need an IT disaster recovery plan?
An IT disaster recovery plan gives a business a structured way to restore technology systems, data, and operations after a disruptive event. Without one, organizations tend to improvise during a crisis, which wastes time and increases the risk of costly mistakes.
Disruptions come in many forms: ransomware attacks, hardware failures, power outages, floods, fires, or even accidental data deletion by an employee. A disaster recovery plan doesn’t prevent these events, but it ensures the business can respond quickly and predictably instead of scrambling to figure out next steps mid-crisis.
How do you start building an IT disaster recovery plan?
Before writing procedures, a business needs to understand what it’s protecting and why. That groundwork comes from two foundational exercises: a risk assessment and a business impact analysis.
What is included in a risk assessment?
A risk assessment identifies the specific threats that could disrupt IT operations, such as cyberattacks, equipment failure, severe weather, or human error. For each threat, the assessment should estimate the likelihood of occurrence and the potential severity of impact.
This exercise helps prioritize recovery efforts. A business located in a flood zone, for example, should weight natural disaster scenarios differently than a company operating entirely in the cloud, whose greater exposure may be a distributed denial-of-service (DDoS) attack or a vendor outage.
What is a business impact analysis, and why does it matter?
A business impact analysis (BIA) identifies which systems, applications, and processes are most critical to daily operations, and quantifies what happens if each one goes offline. The BIA should answer questions like:
- Which systems directly support revenue generation?
- How much data loss can the business tolerate before it becomes damaging?
- How long can each system stay offline before causing serious harm?
- Which departments depend on which systems?
The answers feed directly into two of the most important metrics in any disaster recovery plan: recovery time objective and recovery point objective.
What are RTO and RPO, and why do they matter in disaster recovery?
Recovery time objective (RTO) and recovery point objective (RPO) are the two benchmarks that shape almost every other decision in a disaster recovery plan.
Recovery time objective (RTO) is the maximum acceptable length of time a system can be offline before the disruption causes unacceptable harm to the business. A customer-facing e-commerce platform might have an RTO measured in minutes, while an internal reporting tool might tolerate a day or more.
Recovery point objective (RPO) is the maximum acceptable amount of data loss, measured in time. An RPO of one hour means the business can tolerate losing up to one hour of data — which dictates how frequently backups need to run.
Choose a shorter RTO and RPO if the system in question is customer-facing, revenue-generating, or tied to regulatory obligations. Choose a longer RTO and RPO for lower-priority internal tools where brief disruption causes minimal harm. Setting these benchmarks accurately prevents a business from overspending on recovery infrastructure for low-priority systems, or underinvesting in protection for mission-critical ones.
What data backup strategy should a disaster recovery plan include?
Data backups are the backbone of any recovery effort, but not all backup strategies offer the same level of protection. A disaster recovery plan should specify:
- Backup frequency: How often data is backed up, based on the RPO established during the business impact analysis.
- Backup location: Many organizations follow the 3-2-1 rule — three copies of data, stored on two different media types, with one copy kept offsite or in the cloud.
- Backup verification: A schedule for routinely testing that backups are complete, uncorrupted, and actually restorable.
- Retention policy: How long backup data is kept before it’s deleted or archived, often shaped by industry regulations.
A backup that has never been tested is not a reliable backup. Plenty of organizations have discovered, mid-crisis, that their backup files were corrupted or incomplete — a mistake that is entirely avoidable with routine verification.
Who should be responsible for executing the disaster recovery plan?
A disaster recovery plan needs clearly defined roles so that, during an actual incident, no one wastes time figuring out who’s in charge of what. At minimum, the plan should designate:
- A disaster recovery coordinator who oversees the overall response and makes final decisions.
- Technical recovery teams responsible for restoring specific systems (networks, servers, applications, databases).
- A communications lead responsible for keeping employees, customers, and stakeholders informed.
- An executive sponsor who can authorize resource allocation and approve major decisions, such as whether to pay a ransom demand or disclose a breach publicly.
Each role should list backup personnel too. If the person responsible for restoring the customer database is unreachable during an incident, the plan needs to name who steps in.
How should a business handle communication during an IT disaster?
Communication breaks down fast during a crisis unless it’s planned in advance. A disaster recovery plan should include:
- Internal communication protocols: How employees are notified of an incident, and through what channel if email or the primary network is down (a phone tree or a dedicated messaging app, for example).
- Customer communication templates: Pre-drafted messages for common scenarios, so the communications lead isn’t writing from scratch under pressure.
- Stakeholder and regulatory notification procedures: Many industries have legal requirements around how quickly a data breach must be disclosed. Healthcare organizations subject to HIPAA, for instance, must notify affected individuals within 60 days of discovering a breach.
Choose pre-approved messaging templates if your business operates in a regulated industry where incorrect or delayed disclosure could carry legal consequences. Choose a more flexible communication approach if your primary concern is maintaining customer goodwill rather than meeting strict compliance deadlines.
What technical recovery strategies should the plan cover?
Beyond backups, a disaster recovery plan needs documented, step-by-step procedures for restoring technical infrastructure. This typically includes:
- Failover procedures: How traffic and operations shift to a secondary site, server, or cloud environment if the primary system fails.
- System restoration order: A prioritized sequence for bringing systems back online, based on the business impact analysis. Critical systems come first; nonessential tools come later.
- Vendor and third-party contacts: Contact information for internet service providers, cloud hosting partners, cybersecurity consultants, and any other vendor whose support might be needed during recovery.
- Hardware and software inventory: A current list of all critical hardware, software licenses, and configurations, so replacement equipment can be sourced quickly if needed.
How often should a business test its disaster recovery plan?
A disaster recovery plan that’s never been tested is essentially a guess. Testing reveals gaps — outdated contact information, backup files that don’t restore properly, or steps that take far longer than anticipated.
Most organizations benefit from testing at least twice a year, using a mix of methods:
- Tabletop exercises: Walking through a hypothetical disaster scenario as a team, without actually touching live systems.
- Simulation tests: Practicing specific recovery procedures, such as restoring a backup to a test environment.
- Full-scale tests: Actually failing over to a secondary system to confirm the entire process works end-to-end.
After each test, the plan should be updated to reflect lessons learned. Employee turnover, new software, and infrastructure changes can all make a disaster recovery plan obsolete within months if it isn’t reviewed regularly.
Building a disaster recovery plan that actually works when it matters
An IT disaster recovery plan is only as useful as the work a business puts into maintaining it. The strongest plans share a few things in common: they’re grounded in a clear-eyed risk assessment, built around specific recovery objectives, assigned to named people rather than vague departments, and tested often enough that nobody is reading the instructions for the first time during an actual emergency.
Start by identifying your most critical systems through a business impact analysis, then work backward to set realistic RTOs and RPOs. From there, document backup procedures, assign roles, and put a testing calendar on the books. A disaster recovery plan built this way won’t just sit in a drawer — it will actually hold up when your business needs it most.
Frequently asked questions
What’s the difference between a disaster recovery plan and a business continuity plan?
A disaster recovery plan focuses specifically on restoring IT systems and data after an incident. A business continuity plan is broader, covering how the entire organization — including staffing, facilities, and supply chains — keeps operating during and after a disruption. Disaster recovery is typically one component within a larger business continuity plan.
How much does it cost to create an IT disaster recovery plan?
Costs vary widely depending on business size, infrastructure complexity, and whether the plan is built in-house or with outside consultants. Smaller businesses may spend a few thousand dollars on backup tools and planning time, while enterprises with complex, regulated environments can spend significantly more on redundant infrastructure and dedicated disaster recovery services.
How long does it take to recover from an IT disaster?
Recovery time depends entirely on the recovery time objectives set for each system and how well the plan has been tested. Businesses with well-rehearsed plans and redundant infrastructure can often restore critical systems within hours; those without a tested plan may face days or weeks of disruption.
What are the biggest risks of not having a disaster recovery plan?
Without a plan, businesses face extended downtime, higher data loss, regulatory penalties for delayed breach disclosure, reputational damage, and in severe cases, permanent closure. The absence of clear roles and procedures also tends to turn a manageable incident into a prolonged crisis.
Who should be involved in creating a disaster recovery plan?
IT leadership typically drives the planning process, but an effective plan involves input from department heads, executive leadership, legal or compliance teams, and sometimes outside cybersecurity consultants. Including stakeholders from across the business ensures the plan reflects real operational priorities, not just technical assumptions.
