Disaster Recovery Planning (DRP) is not
just about computer system availability. While this was the original
concept, today, the definition of disaster recovery has been
broadened to mean: "The ability to respond to an interruption
in services by implementing a disaster recovery plan to restore an
organization's critical business functions." Business continuity
planning includes disaster recovery for
computer systems and services as one component while stressing continuous
availability of all critical services.
Disaster recovery planning is the technological aspect of
business continuity planning. This is meant to include the plans
and preparations which are necessary to minimize loss and ensure
continuity of the critical business functions of an organization in
the event of disaster.
Disaster recovery (DR) has taken on a new sense of urgency in recent years.
issues like terrorism, hackers, computer
viruses, an increased reliance on computers, and the increasing occurrence of
emergencies and disasters have
all led to increase our focus on preparing for disasters.
Disaster recovery planning is a crucial component of enterprise
risk management and business continuity
planning. It is essential
for ensuring continuity of operations. Prior to the creation
of a disaster recovery plan, it is essential to review the entire business
continuity plan and to consider the potential impacts of
disasters. A business impact analysis must be performed so
that you can understand the underlying risks. This
comprehensive planning process is the foundation upon which a
sound disaster recovery plan should be built.
In today's interconnected economy, organizations are more vulnerable than ever to the possibility of technical difficulties
disrupting business. Any disaster, from floods and fires to viruses and
cyber terrorism, can affect the availability, integrity, and confidentiality of critical business resources and leave an organization virtually
dead in the water. In our wired economy, these business
interruptions can quickly lead to losses in the millions.
Disaster recovery strategies include the use of alternate sites (hot, warm, and cold
sites); redundant data centers; disaster insurance; business impact analyses; and legal liabilities.
The first step in the disaster recovery process is to perform
a business impact analysis that considers all of the the
potential impacts from each type of disaster. Disaster
Recovery Plans should consider how to deal with these possible
- Natural Disasters (Earthquake, Fire, Flood,
- Terrorist Acts (Weapons of Mass
- Power Disruptions, Power Failure
- Computer Software or Hardware Failures
- Computer Shutdowns due to Hackers, Viruses,
- Processing Shutdowns
- Labor Strife (Walkouts, Shutdowns)
Having determined the potential events you must next look at
the impacts of each event and the magnitude of the resulting
disruptions. This critical activity will determine which
scenarios are most likely to occur and what recovery processes
Your disaster recovery plan must be integrated with your overall
enterprise continuity management approach and must
be tested through drills and exercises that test your plans, your people,
and your tools.
