Regular system backups protect the information in your system from
irretrievable loss by providing a copy of the information. However,
natural and man-made problems, such as smoke, noxious fumes, explosion,
flood, earthquake, and sabotage, can still threaten both your backup
media and your system hardware. A disaster recovery plan protects your
organization from such potential disablement by establishing procedures
for duplicating and safely storing backup media and maintaining a site
for "substitute" computer hardware. Although implementing a disaster
recovery plan is time-consuming and costly, saving your system from an
unexpected disaster is almost always worth the effort. Refer to Chapter
13, "Disaster Recovery," for more detail.
