The different types of disasters can be classified into two categories. They are:
A natural disaster is a major adverse event resulting from the earth’s
natural hazards. Examples of natural disasters are floods,
tsunamis, tornadoes, hurricanes/cyclones, volcanic
eruptions, earthquakes, heat waves, and landslides.
Man-made disasters are the consequence of technological or human
hazards. Examples include stampedes, urban fires, industrial
accidents, oil spills, nuclear explosions/nuclear radiation and acts
Develop disaster recovery plan
Step1: Risk Analysis
The first step in drafting a disaster recovery plan is conducting a
thorough risk analysis of our computer systems. List all the possible
risks that threaten system uptime and evaluate how imminent they are in our particular IT shop.
Step 2: Establish the Budget
Once you’ve figured out your risks, ask ‘what can we do to suppress them, and how much will it cost?’
Step 3: Develop the Plan
The feedback from the business units will begin to shape your DRP procedures. The recovery procedure should be written in a detailed plan or “script.” Establish a Recovery Team from among the IT staff and assign specific recovery duties to each member and Define how to deal with the loss of various aspects of the network and specify who arranges for repairs or reconstruction and how the data recovery process occurs.
Step 4: Test
Once your DRP is set, test it frequently. Eventually you’ll need to
perform a component-level restoration of your largest databases to get a realistic assessment of your recovery procedure, but a periodic
walk-through of the procedure with the Recovery Team will assure
that everyone knows their roles.
