What does disaster recovery focus on in information systems?

Disaster recovery in information systems specifically focuses on the processes and strategies needed to restore critical business functions after a disruption or disaster. This involves having a comprehensive plan that outlines how to recover and protect the information technology infrastructure and operations vital to an organization’s survival. The goal is to minimize downtime and data loss, ensuring that essential services can be resumed as quickly as possible in the event of a disaster, whether it's a natural event, cyberattack, or system failure.

The emphasis is on recovery rather than prevention or elimination of data, which differentiates it from activities aimed at preventing disasters or maintaining regular operations. While maintaining business continuity and safeguarding against data loss are crucial components of an overall risk management strategy, the primary focus of disaster recovery is specifically on getting back to operational capacity after an event has occurred.
