What is recovery time objective?

The answer to this question is: The recovery time objective (RTO) is the maximum tolerable length of time that a computer system, network or application can be down after the failure or a disaster occurs. The RTO is a function of the extent to which the interruption disrupts the normal functioning and the amount of the loss of revenue per unit time as a result of the disaster. These factors are in turn affected equipment and application (s). The RTO is measured in seconds, minutes, hours or days, and is an important consideration in planning disaster (DRP).
Numerous studies have been conducted in an attempt to determine the cost of downtime for various applications in the enterprise. These studies indicate that the cost depends on long-term and intangible effects as well as immediate, short term or tangible factors. Once the reverse takeover of an application has been defined, administrators can decide who recovery technologies disaster are best suited to the situation. For example, if the RTO for a given application is one hour, redundant backup data on external hard drives May be the best solution. If the RTO is five days, then tapes, compact disc recordable (CD-R), or offsite storage on a remote web server May be more convenient.
