What level of Recovery Time Objective (RTO) will a critical monitoring system have?

Very low RTO, close to zero

The system is critical for the business and must be returned to operation as quickly as possible

Very low RTO, close to zero

The RTO is a measure of the users tolerance to downtime. In case of critical systems, generally RTO is zero or near to zero. Low RTO indicates that system should be resumed at the earliest. For example, if RTO is 2 hours, system should be resumed within 2 hours and if RTO is 72 hours, system should be resumed within 72 hours. Thus, in case of critical system generally RTO is kept low to ensure immediate resumption of services.
