5. What does a backup plan contain?
The backup plan specifies how an organization uses backup
files and equipment to resume information processing.

What factors contribute to the success of a backup plan?
For a backup plan to be successful, the
organization must back up all critical
resources.
The location of the alternate computer
facility is important.
Also, additional people, including
possibly nonemployees, must be trained in
the backup and recovery procedures because
organization personnel could be injured in a
disaster.
Some organizations preinstall all
the necessary hardware, software, and communications
devices at the alternate computer
facility. These facilities immediately are ready
in the event of a disaster. In other cases, the
alternate computer facility is simply an empty
facility that can accommodate the necessary
computer resources, if needed.
One more
alternative is to enter into a reciprocal backup
relationship with another firm, where one firm
provides space and sometimes equipment to
the other in case of a disaster.
