Every business and organization should have some provision for
business continuity should a calamity strike. The level of protec-
tion that’s right for your business will depend on the resources you
need to provide to ensure continuity (see Figure 9-4). In extreme
cases, this may mean a fully-functional backup site of your own
located an appropriate distance from your primary IS facility.
Many businesses enlist the services of hot-site vendors that provide
recovery systems and facilities on a contractual basis.
Most backup management software includes features to help you
recover your data following a disaster. Image backups are often
used for disaster recovery purposes. It’s important that you store
data off site on a regular basis.
