What Is a Disaster?

For the purpose of this guide, a disaster is any situation in which the day-to-day access to data (for example, working files, software programs, or system files) is disrupted. A disaster can also damage network components, such as data, devices, hardware, media, and software.

A disaster can result from any of the following:

•Computer viruses that can corrupt data

•Hardware and software failures

•Infrastructure interruptions, inconsistencies, or loss of services, such as communication or network connections

The degree of loss during a disaster can range from one or more files to an entire computer system. The severity of the disaster determines the procedures necessary to recover data.

Note: The term autochanger refers to a variety of backup devices: autoloader, carousel, datawheel, jukebox, library, and near-line storage.
