Disaster recovery in simple terms is all about planning for recovery of technological infrastructure carrying critical importance to an organization after occurrence of human induced or natural disaster. Disasters are categorized into two types.
First is Natural Disasters like earthquakes, floods, tornadoes etc., whereas Human Induced Disasters are those created by man like hazardous spills, bio terrorism and infrastructure failure. Though natural disasters are impossible to be prevented but human induced disasters can be prevented after careful planning. Mitigation planning and surveillance can be termed as invaluable concepts in order to avoid or lessen losses from such events. Disaster recovery has become a vital element of enterprise computing. Simple things are becoming more complex since the complexity in devices, systems and overall organizations has become rampant.
Today every business requires disaster recovery plans for implanting a successful business strategy. Though it is a difficult concept but still everyone needs to be equipped with it. In simple terms it defines the ability to continue with vital work after occurrence of catastrophic disasters whether natural or human made ones. Thus, having an efficient and effective disaster recovery plan is an essential part of each enterprise. It takes into account the important aspects of business i.e the elements which make business and keep it ongoing. Such elements vary from business to business and therefore, disaster recovery plan should be built up keeping in consideration the individual requirements of businesses.
As an initial step towards building up of a recovery plan is to craft and map out the most critical aspects of an individual's day to day business. For example, if the major part of an enterprise work deals with carrying of contracts via communicating over phone with clients then it is essential to address a backup phone system. Though it may seem simple but in real terms it is very complex to maintain integrity.
Data safety is yet the most vital and overlooked area of disaster recovery. You cannot call your clients if you don't possess their requirements and proper contact addresses. Similarly taking new contracts become difficult if there is no access to your inventory system. Thus, disaster recovery involves the inclusion of frequent backups of all vital and critical information, data and records, digital and hard copies and storing them in a secured way in a remote location of enterprise. Time frame is also an important aspect in disaster recovery and should be taken into consideration while planning.
