Disaster recovery (DR) and business continuity (BC) are two related concepts but with distinct focuses. The main difference between the two is their scope and objectives.
1. Scope:
- Disaster Recovery: DR focuses on recovering and restoring IT infrastructure and systems after a disaster or disruptive incident, such as a natural disaster, cyber attack, or hardware failure. It mainly deals with the technical aspects of the organization's operations.
- Business Continuity: BC, on the other hand, encompasses a broader scope. It involves planning and implementing measures to ensure the overall survival and continuity of the entire organization during and after a disruptive event. BC covers not only IT infrastructure but also people, processes, and facilities.
2. Objectives:
- Disaster Recovery: The primary objective of DR is to minimize the downtime and recover IT services as quickly as possible. It aims to restore critical systems, applications, and data to previous operational levels.
- Business Continuity: BC aims to maintain and continue essential business functions during and after a disruption. It focuses on keeping the organization functional, providing necessary resources, and minimizing the impact on customers, stakeholders, and the overall business reputation.
3. Timeframe:
- Disaster Recovery: DR is typically focused on short-term recovery, aiming to restore systems and services within the Recovery Time Objective (RTO), which defines the maximum tolerable downtime.
- Business Continuity: BC goes beyond the short-term and involves long-term planning for how the organization will continue to operate during an extended disruption. It incorporates strategies for resilience, risk management, and adapting to a changing environment.
In summary, disaster recovery deals with restoring IT systems after an incident, while business continuity aims to maintain overall organizational functionality during and after a disruption. Both DR and BC are crucial components of a comprehensive disaster management plan.
