Previously called ‘hot stand-by’, provides for the immediate restoration of services following any irrecoverable incident. It is important to distinguish between the previous definition of ‘hot stand-by’ and ‘immediate recovery’. Hot stand-by typically referred to availability of services within a short time-scale such as 2 or 4 hours whereas immediate recovery implies the instant availability of services.
