What is the purpose of a disaster recovery plan quizlet?

A disaster recovery plan is a documented process or set of procedures to recover and protect a business IT infrastructure in the event of a disaster. The purpose of having a disaster recovery plan is to ensure that critical business systems can be restored as quickly and smoothly as possible after a major disruption or disaster. An effective disaster recovery plan minimizes downtime and data loss while providing a clear framework for how to respond and recover from a crisis situation.

Why is a disaster recovery plan important?

There are several key reasons why having a robust and well-thought-out disaster recovery plan is crucial for any organization:

  • Minimizes downtime – A disaster recovery plan helps get critical systems and operations backup and running more quickly. The faster systems can be restored, the less financial damage and loss of productivity from prolonged downtime.
  • Preserves data integrity – The plan should detail how data backups will be accessed and restored. This is key to avoiding permanent data loss that could severely harm an organization.
  • Maintains compliance – Some industries and regulations require a disaster recovery plan to be in place. Having one helps organizations stay compliant.
  • Reduces risk – A disaster recovery plan mitigates risk by mapping out in advance how to respond to disruptions. It helps limit chaos, confusion and serious financial impacts.
  • Provides continuity – An effective plan helps an organization continue critical operations and keep serving customers, even when a disaster occurs.
  • Protects the business – Quick disaster recovery demonstrates resilience and helps safeguard the company’s reputation and long-term viability.

In short, the purpose of a disaster recovery plan is to protect the organization by preparing in advance for effective incident response and recovery.

What are the key elements of a disaster recovery plan?

A comprehensive disaster recovery plan will include the following key elements:

Emergency response procedures

The plan should outline who will be responsible for leading response efforts, who will be part of the emergency response/recovery team, and the immediate steps that should be taken in the event of a crisis to secure facilities, protect employees, notify relevant parties, etc.

Impact analysis

A business impact analysis will identify the company’s most critical systems, operations and resources. The plan can then prioritize the recovery of the most essential functions in the aftermath of a disaster.


The plan should describe scheduled backups, what data/systems are being backed up, the media used, where backups are stored offsite, and how frequently backups are performed. Multiple recovery points should be included.

Policies and procedures

Detailed procedures for recovering critical technology infrastructure, applications, data, and networks will enable the business to efficiently restore operations. Testing and rehearsing procedures also improves preparedness.

Technology recovery strategies

Alternative business locations, computer equipment, backups, networks, telephone services that can be utilized to restore technology systems should be outlined as part of a comprehensive IT disaster recovery approach.

Vendor contacts

Contact information for hardware vendors, software vendors, disaster recovery specialists, emergency services, utilities, and other key third parties who may need to be engaged in a crisis scenario.

Communications plan

A plan for communicating with employees, customers, vendors, authorities, media and other stakeholders during and after an emergency situation.

Long-term recovery plans

If the primary location cannot be recovered in a reasonable timeframe, the plan should outline steps to recover business operations at an alternative site or new facility.

How often should a disaster recovery plan be updated?

To be effective, a disaster recovery plan needs to be regularly reviewed and updated to account for changes within the organization. Important factors that can impact the plan include:

  • New hardware, applications, data resources or technology infrastructure
  • Changes to operations, processes or business priorities
  • Changes to contact details for staff, vendors or other stakeholders
  • Updates to regulatory or compliance requirements
  • Alterations to facilities, resources or evacuation sites

Organizations should review and update their disaster recovery plan at least annually. However, more frequent updates may be warranted depending on the scope of changes within an organization. Any major changes that could impact disaster recovery should trigger an immediate review. Training staff on updated plans should also be part of the maintenance process.

What are some key components of effective disaster recovery testing?

Testing a disaster recovery plan is essential to identify any gaps and improve the plan. Key components of effective disaster recovery testing include:

  • Structured tests – Schedule periodic, comprehensive tests rather than informal testing. Tests should have defined scopes, objectives and timelines.
  • Simulated scenarios – Test impacts from different types of realistic disaster scenarios based on typical risks.
  • Data validation – Ensure data recovery processes fully protect integrity and privacy when restoring from backups.
  • Alternate sites – Test connectivity, equipment and backups stored at alternate sites or cloud providers.
  • Staff training – Test usability for staff tasked with emergency response and recovery processes.
  • Third party engagement – Incorporate vendors, partners, authorities and other external organizations into testing when appropriate.
  • Documentation – Document test scenarios, procedures, results and recommendations to improve the plan.

Performing periodic disaster simulations through structured testing helps improve recovery competency and confidence within the organization.

What are some potential disasters that a recovery plan should address?

Disaster recovery plans are designed to enable recovery from catastrophic events that significantly disrupt normal business operations. Some potential disasters to address include:

  • Natural disasters – Storms, floods, fires, earthquakes that damage facilities and technology infrastructure.
  • Power outages – Disrupt productivity and damage systems without generators or battery backups.
  • IT system failures – Crashes, viruses, malware or errors that impair hardware systems and networks.
  • Cyberattacks – Vulnerabilities exploited to steal or corrupt critical company data and systems.
  • Human errors – Mistakes by staff or partners that result in catastrophic losses or failures.
  • Supply chain disruptions – Logistics issues preventing operations from accessing required resources.
  • Health crises – Outbreaks that close facilities and impact workforce availability.

The recovery plan should take into account the most likely threats based on the company’s risk profile, location and industry. Prioritizing the highest impact scenarios will drive the most relevant emergency response and recovery strategies.

What are the primary differences between a disaster recovery plan and a business continuity plan?

There are distinct differences between a disaster recovery plan and a business continuity plan:

Disaster Recovery Plan Business Continuity Plan
Focused on restoring technology systems and infrastructure after a disaster Broader plan designed to maintain operations during any type of business disruption
IT driven – managed by IT leaders with input from other departments Organization-wide effort led by senior management with participation across departments
Tactical plan focused on short-term recovery after an incident Strategic plan focused on long-term strategies to continue critical processes
Detailed step-by-step procedures for recovery Conceptual framework of priorities, roles, strategies and procedures
Triage mindset to urgently restore critical systems Proactive approach to identify risks and maintain resilience

An effective business continuity management program integrates both disaster recovery and business continuity. The disaster recovery plan is a key component of managing risk and ensuring operations can continue in a crisis.

What are some key differences between a hot site and cold site in disaster recovery?

Hot sites and cold sites describe two different types of backup facilities that can be utilized for disaster recovery:

Hot Site

  • Fully equipped alternate facility that can quickly activate systems and operations
  • Contains near replicas of critical technology infrastructure
  • Allows rapid resumption of business processes
  • Costly to operate full-time on standby

Cold Site

  • Basic facility with space, power, cooling capabilities
  • Does not contain installed computer hardware, networks, telecoms
  • Faster to establish but slower to activate than a hot site
