In different rooms that have are separated by a third room(s) that is at least of 70 feet wide between the rooms.

Different floors on the same wing of a building in rooms that are horizontally offset by a minimum of 70 feet with fire walls between the rooms that are on different floors.

Different wings on the same building, in rooms that are separated by more than 300 feet.

Different buildings on the same campus.

Less than 62 miles apart, but not on the same campus.

Regional clusters less than 93 miles apart. Geographic redundancy reduces the likelihood of events such as power outages, floods, HVAC failures, lightning strikes, tornadoes, building fires, wildfires, and mass shootings would disable the system. Geographic redundancy corrects the vulnerabilities of redundant devices deployed by geographically separating backup devices.

Dissimilar redundancy is often used with software, because identical software contains identical flaws. The voting method may involve additional complexity if the two things take different amounts of time. The idea is that the different things are unlikely to contain identical flaws. Unlike traditional redundancy, which uses more than one of the same thing, dissimilar redundancy uses different things. The models are subject of studies in reliability and safety engineering. Parallel and combined systems demonstrate different level of redundancy. Bridges that failed due to lack of redundancy include the Silver Bridge and the Interstate 5 bridge over the Skagit River. A structure without redundancy is called fracture-critical, meaning that a single broken component can cause the collapse of the entire structure. Structures are usually designed with redundant parts as well, ensuring that if one part fails, the entire structure will not collapse.

Applied in the case of software, code written independently and distinctly different but producing the same results for the same inputs.

Distinct functional redundancy, such as both mechanical and hydraulic braking in a car.

Software redundancy such as N-version programmingĪ modified form of software redundancy, applied to hardware may be:.

Time redundancy, performing the same operation multiple times such as multiple executions of a program or multiple copies of data transmitted.

Information redundancy, such as error detection and correction methods.

Hardware redundancy, such as dual modular redundancy and triple modular redundancy.

In computer science, there are four major forms of redundancy, these are:

5 Calculating the probability of system failure.

Redundancy may also be known by the terms "majority voting systems" or "voting logic". Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extraordinarily small often outweighed by other risk factors, such as human error.

In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. An error in one component may then be out-voted by the other two. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR). In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
