The correct answer is that this statement is true. Backup systems are a type of corrective control designed to restore systems and data to their appropriate state following an incident, such as data loss or corruption. They are essential for business continuity and disaster recovery strategies.

Incorrect answers can easily mislead as they may reference related concepts, such as redundant systems or preventive controls, which serve different purposes. Redundant systems are intended for immediate failover to avoid downtime, while preventive controls are designed to stop incidents from occurring in the first place.
