Why is data backup important in cybersecurity?

Data backup is a critical aspect of cybersecurity because it ensures recovery from data loss events. In the event of a cyber incident, such as ransomware attacks, system failures, or accidental deletions, having backups means that an organization can restore its data to a previous state. This capability minimizes downtime and reduces the impact on business operations. It is essential for maintaining data integrity and availability, allowing organizations to quickly recover and continue functioning after unexpected disruptions.

While other options may touch on related concepts in cybersecurity, they do not specifically address the necessity of having an effective strategy to restore lost or compromised data, which is the primary reason backups are essential.
