What is disaster recovery?

Disaster recovery (or DR) is part of a broader business continuity strategy, and refers to the processes and policies organizations use to restore IT systems and resume operations after a disruption. Events can include power outages, cyberattacks, hardware failures, or natural disasters. If infrastructure is damaged or unavailable, applications and data can be recovered from backups or replicated environments at another location.

How does disaster recovery work?

Disaster recovery strategies typically focus on three areas: prevention, preparedness, and recovery. Organizations identify critical systems, back up or replicate data, establish recovery procedures, and regularly test their plans. Two key metrics help define recovery requirements:

• Recovery time objective (RTO): The maximum amount of time a system or service can be unavailable before significantly affecting the business.
• Recovery point objective (RPO): The maximum amount of data an organization can afford to lose, measured in time.

RTO and RPO requirements are typically established as part of an organization’s broader business continuity planning.

Why is disaster recovery important?

In a digital business, downtime can quickly translate into lost revenue, missed opportunities, and lost customer trust. A strong disaster recovery strategy helps protect critical data, shorten recovery times, and minimize the business impact of an outage. Effective recovery also depends on preparedness across IT teams, executives, and business leaders.

Benefits and use cases

Disaster recovery helps minimize downtime and data loss while supporting business continuity and resilience. It can also help organizations meet regulatory, contractual, and cyber insurance requirements. Common scenarios include:

• Natural disasters that damage or disrupt physical infrastructure
• Cyberattacks such as ransomware or distributed denial-of-service (DDoS) attacks
• Hardware and system failures
• Power or network outages
• Human error

Recovery plans typically prioritize the most business-critical systems first to reduce operational impact.
