What is Disaster Recovery?
Disaster Recovery (DR) is a set of policies, tools, and procedures that enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. The goal is to minimize downtime and data loss, ensuring business continuity.
Why is Disaster Recovery Important?
- Protects organizations from data loss and operational disruption
- Ensures rapid recovery after unexpected events
- Helps maintain customer trust and regulatory compliance
- Reduces financial and reputational impact of disasters
Types of Disasters
- Natural: Floods, earthquakes, fires, storms
- Technical: Hardware failures, software bugs, power outages
- Human: Cyberattacks, accidental deletions, sabotage
Key Components of a Disaster Recovery Plan
- Risk Assessment: Identify potential threats and vulnerabilities
- Business Impact Analysis (BIA): Determine critical systems and acceptable downtime
- Recovery Strategies: Define methods for restoring systems and data
- Data Backup: Regularly back up data to secure, offsite locations
- Communication Plan: Establish clear communication channels for stakeholders
- Roles and Responsibilities: Assign tasks to specific personnel
- Testing and Drills: Regularly test the plan to ensure effectiveness
- Plan Maintenance: Update the plan as systems and risks evolve
Best Practices for Organizations
