Final answer:
The recovery time objective (RTO) in a business impact analysis is the target time within which a business aims to restore its operations after an interruption, to minimize losses.
Therefore, Correct option B, "The target time to have a down system back up and running,"
Step-by-step explanation:
In a business impact analysis, the recovery time objective (RTO) best describes B. The target time to have a down system back up and running. The RTO is a critical metric in disaster recovery and business continuity planning. It represents the duration within which a business must restore its operations after a disruption to avoid unacceptable losses or damages.
RTO is not the average repair time but a goal set by the business to ensure minimal impact on operations. It differs from the Recovery Point Objective (RPO), which defines the maximum tolerable period in which data might be lost. Setting a realistic RTO is essential for effective disaster recovery strategies and ensuring that the recovery process aligns with business objectives and needs.
