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.
