What are 3 disaster recovery phases?

Disaster recovery is the process of restoring IT infrastructure and systems after a natural or human-caused disaster. There are three main phases of disaster recovery: response, recovery, and restoration. Understanding these phases is crucial for developing an effective disaster recovery plan.

Response Phase

The response phase starts immediately after a disaster occurs. The goal is to assess the damage and minimize further destruction. Key response phase activities include:

  • Activating the disaster recovery team and emergency response procedures
  • Assessing life safety, structural integrity, and utilities
  • Documenting damage through photos/video
  • Stabilizing damaged structures and equipment
  • Setting up an emergency operations center
  • Notifying stakeholders (employees, customers, partners, etc.)
  • Reporting status to executive leadership
  • Triaging IT systems – Determine which are destroyed, disrupted, or intact

The response phase is complete once the initial damage assessment is finished. The focus then shifts to recovery operations.

Recovery Phase

The goal of the recovery phase is to restore critical IT infrastructure and resume normal operations. Key recovery phase activities include:

  • Launching backup facilities to provide interim IT capabilities
  • Procuring necessary supplies and equipment for restoration
  • Cleaning up debris and repairing utilities/facilities
  • Recovering data from backups
  • Reconfiguring networks and systems
  • Validating recovered data/systems
  • Establishing temporary work facilities
  • Facilitating workforce communications and scheduling

The recovery phase continues until the organization’s critical systems and workflows are operational again, even if degraded. The length of this phase varies based on the nature and severity of the disaster.

Restoration Phase

The restoration phase aims to return the organization to normal operations. Activities include:

  • Completing repairs/reconstruction of damaged facilities and infrastructure
  • Procuring permanent replacements for destroyed equipment
  • Reconstituting lost data from archives
  • Testing and validating restored IT systems
  • Transitioning operations from interim to permanent facilities
  • Tuning and optimizing systems
  • Educating employees on enhanced risk mitigation policies
  • Updating disaster recovery plans based on lessons learned

The restoration phase continues until all repairs are finished, operations are stabilized, and a “new normal” is established. This phase can take weeks or months depending on the extent of the disaster.

Key Factors Influencing Disaster Recovery Time

Many factors influence the speed and effectiveness of disaster recovery efforts. Some key considerations include:

  • Redundancy of infrastructure and systems – Backup facilities, redundant connections, mirrored data, etc. can dramatically accelerate recovery time.
  • Business continuity planning – Comprehensive BC/DR planning minimizes confusion and enables a more coordinated response.
  • Emergency preparedness – Employee training, emergency supplies, access to financing, and contractual aid agreements help mobilize recovery resources faster.
  • Nature of the disaster – More severe and widespread disasters cause greater destruction and longer recovery times.
  • Accessibility of recovery sites – Proximity and transportation links to backup facilities influence how quickly they can be activated.
  • Availability of people and resources – Pandemic impacts, supply chain disruptions, and labor/material shortages delay recovery.

Organizations should carefully assess these factors when developing disaster recovery plans and evaluating their ability to resume operations after a disruption.

Disaster Recovery Phase Timelines

While disaster recovery timelines vary widely based on many variables, some typical time durations for each phase include:

  • Response – Hours to days
  • Recovery – Days to weeks
  • Restoration – Weeks to months

However, major disasters affecting widespread geographic areas or critical infrastructure can dramatically lengthen these phases. For example, full recovery and restoration from Hurricane Katrina along the Gulf Coast took many months. The COVID-19 pandemic also severely disrupted some business operations for over a year.

Recovery times are also influenced by the availability of insurance coverage and federal disaster assistance. Events declared major disasters can qualify for public aid that helps speed recovery and restoration.

Best Practices for Speeding Disaster Recovery

Organizations can take several steps to accelerate the disaster recovery process:

  • Have redundant infrastructure in diverse locations to avoid simultaneous loss.
  • Keep mirrored data at an offsite facility for rapid restoration.
  • Automate system recovery procedures as much as possible.
  • Maintain emergency response plans, contact lists, and resources.
  • Document system architectures/configurations to simplify rebuilding.
  • Cloud-enable IT systems and utilize managed disaster recovery services.
  • Form mutual aid agreements with other organizations.
  • Educate employees on disaster response procedures.
  • Conduct recovery exercises to improve restoration processes.

Investing in strong business continuity planning is the best way for organizations to minimize downtime and quickly rebound when disasters occur.

Challenges That Can Delay Disaster Recovery

While the goal is always for a swift recovery, many challenges can impede the process:

  • Communication breakdowns – Inability to reach responders, vendors, or employees delays coordinated action.
  • Insufficient planning – Lack of emergency plans, procedures, contact lists leads to confusion.
  • Personnel shortages – Loss of key employees, insufficient training on response procedures.
  • Funding constraints – Lack of accessible capital to procure equipment and materials for restoration work.
  • Supply chain disruptions – Inability to obtain necessary parts/equipment due to vendor damages or logistics interruptions.
  • Alternate site limitations – Backup facilities lack sufficient capacity or capabilities.
  • Unplanned workarounds – Recovering without a roadmap leads to delays from sub-optimal temporary solutions.

Robust contingency planning, emergency response training, and business continuity investments hedge against these hazards to accelerate recovery.

Key Systems to Prioritize for Rapid Recovery

During the response and recovery phases, focus is first directed at restoring mission-critical systems that support urgent needs. Some key systems to prioritize include:

  • Life safety systems – e.g. building environmental controls, fire alarms, security systems.
  • Communications systems – e.g. phones, email, intranet – to coordinate response teams.
  • Operations systems – e.g. ERP, CRM, databases – to resume critical business processes.
  • Transaction systems – e.g. e-commerce, PoS, claims processing – to serve customers.
  • Administrative systems – e.g. VPN, productivity software – to enable workforce connectivity.

Some systems may need to be recovered in stages if immediate full restoration is impossible. The goal is to get basic functionality back online quickly, then enhance to normal capabilities later.

Key Personnel for Disaster Recovery Operations

Effective disaster response requires mobilizing cross-functional teams combining leadership, operations, and subject matter expertise. Key personnel roles include:

  • Crisis management team – Executives who oversee strategic direction and high-level decision-making.
  • Incident commander – Leader who directs on-scene emergency response procedures.
  • Operations coordinator – Manages logistics like communications, transportation, supplies, facilities.
  • IT manager – Assesses damage to systems, leads technical restoration efforts.
  • Facilities manager – Oversees infrastructure repairs, cleanup, reconstruction.
  • HR manager – Helps notify employees, supports workforce arrangements.
  • Communications lead – Distributes status updates to employees, media, government agencies.
  • Call center team – Fields inquiries from anxious customers, community members.

These stakeholders should all be involved in disaster planning and preparedness training to ensure effective execution of response and recovery plans when faced with a real emergency.

Testing and Exercises to Validate Recovery Plans

Recovery plans should be regularly tested through simulated disasters and exercises to validate their effectiveness. Some options include:

  • Tabletop exercises – Scenario discussions to work through response procedures.
  • Drills – Hands-on practice of specific emergency response tasks.
  • Functional exercises – Test specific team roles and capabilities.
  • Full-scale exercises – organization-wide disaster simulations.

Lessons learned from testing can be incorporated to improve plans. Exercises also develop critical experience in recovery procedures for personnel at all levels.

Key Metrics to Track Recovery Progress

Tracking key metrics helps monitor progress through the recovery process. Useful metrics include:

  • Percent of employees accounted for and contacted
  • Percent of critical infrastructure repaired
  • Percent of core systems/applications recovered
  • Percent of lost data restored from backup
  • Percent of customers served/typical volume processed
  • Time to reopen primary facilities
  • Time to return to planned staffing levels

Dashboards displaying these vital signs provide visibility into recovery status for leadership and help identify areas needing focus.

Key Milestones Indicating Recovery Phase Completion

Each recovery phase involves restoring critical capabilities before transitioning to the next stage:

Response Phase Milestones:

  • Life safety stabilized; major hazards contained
  • Emergency facilities and resources deployed
  • Initial damage assessment complete
  • Critical systems triaged

  • Basic customer services resume

Restoration Phase Milestones:

  • Permanent repairs and reconstruction complete
  • All data fully restored
  • Operational capabilities back to normal
  • New risk mitigations and policies in place

Celebrating these milestone accomplishments helps maintain momentum and morale through what can be a long, arduous recovery process.

Common Mistakes to Avoid in Disaster Recovery

Some common mistakes that can impede effective disaster recovery include:

  • Not keeping recovery plans and documentation up to date
  • Failing to secure adequate emergency funding
  • Not having backups stored in multiple locations
  • Lack of redundancy for critical infrastructure
  • Inadequate training on response procedures
  • Allowing insurance policies to expire
  • Poor communication to employees and customers
  • Unclear priorities and accountability
  • Rushed restoration leading to wasted effort

Avoiding these pitfalls requires investing in thorough preparedness combined with testing. An ounce of prevention is truly worth a pound of cure when it comes to swift disaster recovery.

Software That Can Help With Disaster Recovery

Specialized software tools can help streamline many disaster recovery functions:

  • Emergency notification systems – Quickly contact employees, mobilize responders.
  • Backup/recovery tools – Replicate data, automate system restores.
  • Incident management systems – Track damage, response tasks, restoration progress.
  • Document management systems – Store recovery plans and procedures.
  • Risk management software – Identify vulnerabilities, model scenarios.
  • Remote collaboration software – Secure workforce communications when normal systems are down.
  • Mobile device apps – Provide status notifications, safety alerts.

These solutions enhance visibility, speed coordination, and reduce the human effort required for smooth disaster recovery.

The Importance of Disaster Recovery for Business Resilience

Effective disaster recovery capabilities are essential for overall business resilience and continuity. Without the capacity to respond, recover and restore operations after adverse events, organizations leave themselves vulnerable to existential threats. Investing in thorough emergency planning and redundancy pays dividends when crises inevitably strike.

Some key benefits strong disaster recovery plans provide for business resilience include:

  • Minimizing downtime – Rapid recovery prevents prolonged business interruptions that can be financially devastating or fatal.
  • Reducing data loss – Backup and restoration capabilities prevent irrecoverable loss of vital business information and records.
  • Maintaining cash flow – Restoring revenue-generating activities quicker preserves financial stability.
  • Averting reputation damage – Quickly resuming services preserves trust and credibility with customers.
  • Protecting shareholder value – Reduced risk exposure provides investor confidence in long-term prospects.

With so much at stake, disaster recovery should be a top priority element of any business continuity strategy.


Robust disaster recovery capabilities require significant forethought, planning, and investment. While the process can be complex and time-consuming, it is essential for bouncing back from disruptions. The three recovery phases – response, recovery, and restoration – each have distinct objectives that transition an organization from chaos to calm. Understanding the key activities, personnel, systems, metrics, and milestones in each phase allows developing and executing effective response and restoration plans. With proper emergency preparation and diligent testing, companies can minimize the impacts of adverse events and demonstrate resilience in the face of calamity.
