A disaster recovery plan describes on how an organisation will deal with potential disasters. Just as a disaster is an event that makes the continuation of normal functions impossible, a disaster recovery plan consists of the precautions taken so that the effects of a disaster will be minimised, and the organization will be able to either maintain or quickly resume mission-critical functions.
Any data disaster recovery planning would involve an analysis of business processes and continuity needs; it may also include a significant focus on disaster prevention. Disaster recovery services & software are becoming an increasingly important aspect of enterprise computing. As devices, systems, and networks become ever more complex, there are simply more things that can go wrong. As a consequence, recovery plans have also become more complex.
Many companies today lack a solid backup and recovery plan. Appropriate plans vary from one enterprise to another, depending on variables such as the type of business, the processes involved, and the level of security needed. Disaster recovery solutions may be developed within an organisation or purchased as a software application or a service. |
