For an IT operation a disaster is not always equated only to the loss or damage of expensive equipment and infrastructure. In this context a disaster is instead each crucial, far-reaching catastrophic event for an IT operation. For example, it can be a catastrophe for a company if business-critical applications crash as a result of the incorporation of software patches. Therefore, a disaster does not necessarily have to be an event that causes the destruction of physical assets but instead is defined through the business-related damage caused by an event.

Minor outages, such as the failure of a component within a computer network services
system or even the breakdown of a complete system (server, disk subsystem), have only a minor or medium impact on IT operations. Outages of this kind statistically occur somewhat frequently and usually affect only one or a few components within the IT environment. High-availability solutions such as RAID and server clustering offer protection against minor failures by eliminating or reducing their impact.
