Disaster Recovery practice is usually based around replicating most important infrastructure components in a separate physical location. Once the primary location becomes unavailable due to a disaster caused by any type of factor including natural disaster, power failures, loss of connectivity, virus attacks, etc., the secondary location can be used to access data and continue performing day to day operations.
In some situations customers like to use primary and secondary site on active/active basis where secondary site shares the performance load with primary site on regular basis.
While planning for additional redundant location a number of factors need to be considered such as user traffic distribution, geographical user locations, failure detection, etc.
