Chapter 5.7. Protecting Data > Disaster Recovery

Disaster Recovery

There are many potential threats to systems. These include sabotage from people inside and outside the company, theft of equipment, fire, and flood (including floods caused by failures of the building's own plumbing or fire-suppression systems). In some parts of the world, terrorist bombs are a threat, and in others, earthquakes must be allowed for.

A disaster is anything that results in the complete destruction of the computer system, although this will almost always be part of a wider picture. If the building has been left unusable, the plan should include where people will be accommodated. It should also decide which other parts of the organization can take over the work. The function of the disaster recovery plan is to define how normal (or at least near normal) services will be restored to users. Because this restoration will be happening in a chaotic environment (after a bomb, earthquake, fire, or flood) the plan is important.
