The disaster recovery manual is a set of agreed actions that will be implemented at the declaration of a disaster. The idea is that, upon such a declaration, you can open up the manual and follow the procedures agreed within it, precisely, without having to negotiate the details. It is done that way because usually at the moment of a disaster it is not appropriate to begin such negotiations. It therefore differs from contingency plans and risk management. The disaster recovery manual is therefore usually restricted to major incidents such as the loss of the mainframe from fire or explosion (terrorism is a big concept today) or a major loss of the system. The disaster recovery manual is usually related to hot, warm or cold aternative sites or switching over to alternative or outsourced networks for an interim period.
