Importance and Adjustment of the Disaster Recovery System
Posted on | October 18, 2011 | No Comments
A disaster recovery system is composed of the process, policies and procedures involved in preparing for recovery or continuation of the technology set up essential in the organisation’s operations after a disaster which could be natural or caused by humans. It is a component of business continuity.
- Importance of Disaster Recovery in Organisations – Large amount of possible profits, investments or assets could be lost by both big or small business organisations if when the timing of the occurrence of a disaster implies so. Thus, disaster recovery and the installation of a disaster recovery system has gained huge importance.
- Disasters Classified – There are two principal categories of disasters and they are natural disasters and human-induced disasters. Natural disasters include hurricanes, floods, tornadoes or earthquakes. Preventing a natural disaster is impossible; however, courses of action like planning procedures which can reduce or avoid losses can be done. Disasters triggered by humans include infrastructure failure, hazardous material spills or bio-terrorism. Mitigation and surveillance are irreplaceable in lessening or avoiding adverse effects in account of these events.
- System Design with Adjustment – A disaster recovery system should be properly formulated. Before selecting a disaster recovery strategy, the planner of the disaster recovery plan must use the overall business continuity system plan as a reference. Important elements like recovery point objective and recovery time objective are key to making a recovery plan that is consistent. They are called metrics and they should be mapped to the underlying information technology systems and infrastructure that support those processes. After this, the disaster recovery planner can define the scope of the business continuity management. It is important to note that the budget allocation for information technology dictates the quality of the disaster recovery the company can afford. Even though it is ideal for an organisation to aim for zero data loss and zero time loss, spending for this aim might be counterproductive and thus can be compromised.
