In information technology, disaster recovery is defined as a set of actions that are taken in the event that a major disaster occurs, causing unplanned outages and possible loss of important data. The objective is to minimize the adverse effects caused by such disasters, and to help prevent the occurrence of others in the future. Disaster recovery can be something that is government involved, or it can pertain to individual private companies or organizations. Disasters can include computer-related issues such as hacker attacks and computer viruses, electrical issues such as power failures and underground cable cuts resulting in such failures, and natural disasters such as fires, floods, and earthquakes. Human error can also cause loss of data and vital pieces of information as networks and computer systems may be down for a time. There are, however, steps that can be taken to plan for disaster recovery and help prevent the occurrence of such disasters.
One of the most important aspects of disaster recovery planning is business continuity. This involves insuring that the critical business processes of an organization will be maintained in the event of a disaster. While this pertains to every aspect of the business, the backing up of computer data is especially important when referring to the areas of the organization that use IT systems since this is where the data is stored.
The topics below will provide information on why disaster recovery planning is important, reasons it is necessary, what a disaster recovery plan is and how it works, and the process for formulating such a plan. These sections also include information about the various types of disaster recovery technology and how it is used, the importance of business continuity planning, how to backup and recover data, and how to help prevent data loss in the event of future disasters. Not long ago, disaster recovery was a long and tedious process, and with older technology it was often only minimally successful. With today’s technology, however, disaster recovery can happen in a more timely manner, and be much more successful.
