A security manager needs to implement a backup solution as part of the disaster recovery plan. The system owners have indicated that the business cannot afford
to lose more than a day of transactions following an event where data would have been restored. The security manager should set a value of 24 hours for the:
A.
recovery time objective
B.
service level agreement
C.
recovery point objective
D.
system backup window
E.
disaster recovery plan
RTO is the recovery point objective (RPO). The RPO is a measurement of how much loss can be accepted by the organization when a disaster occurs. This acceptable loss is measured in time. The RPO measurement is independent from RTO. For example, if an organization can survive only two hours of lost data, then the RPO is two hours. The RPO is a measurement of how much data can be lost prior to the point in time of a disaster, whereas the RTO is how much time after the disaster the company has to
recover operations. Generally, backup systems are designed to prevent data loss over the RPO limit, and recovery solutions are designed to return things to normal before the RTO is exceeded.

Good explanation Nazrie. One correction, though; RTO is the recovery time objective (RTO), which as you correctly state, “RTO is how much time, after the disaster, the company has to recover operations”.
But I think we all get it. Thanks.
