A disaster is a natural or manmade event which results in widespread human loss, loss of livelihood, property and life.

What is a DISASTER?

THE DISASTER MANAGEMENT CYCLE

CON… Mitigation: any activity that reduces either the chance of a hazard taking

place or a hazard turning into disaster.

Risk reduction: steps and actions that seek to avoid future risks as a result of a disaster.

Prevention: avoiding a disaster even fast.

Preparedness: plans or preparations made to save lives or property, and help the response and rescue service operations. This phase covers implementation/operation, early warning systems and capacity building so the population will react appropriately when an early warning is issued.

Response: includes actions taken to save lives and prevent property damage, and to preserve the environment during emergencies or disasters. The response phase is the implementation of action plans.

Recovery: includes actions that assist a community to return to a sense of normalcy after a disaster.

It involves steps to ensure that communities and services are capable of coping with the effect of disaster.

Disaster Preparedness

It involves steps taken in anticipation of, during and immediately after a disaster to ensure that the effects are minimized.

Disaster Response

It involves steps, which support emergency affected areas in reconstruction of the physical infrastructure and restoration of economic and emotional well being.

Disaster Recovery

Define your recovery point objective and recovery time objective goals according to your business needs. You can achieve those goals through regular IT operations, as described in the following topics:

Backing up dataA backup is a copy of the production environment. There are several ways to make a backup. Each method imposes some constraints on the production environment, and each presents some advantages and disadvantages.Restoring dataIf a disaster occurs in the primary data center, you can continue to provide business support if you have a valid backup. You restore the backup to the secondary data center and then verify the restored data.Verifying restored dataAfter you restore the backup of your production environment to the secondary data center, verify the data to determine whether the backup is a valid copy.
