Disaster Recovery

Disaster recovery is the process, policies and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster. Disaster recovery focuses on the IT or technology systems that support business functions.

Disasters can be classified in two broad categories. The first is natural disasters such as floods, hurricanes, tornadoes or earthquakes. While preventing a natural disaster is very difficult, measures such as good planning which includes mitigation measures can help reduce or avoid losses. The second category is man made disasters. These include hazardous material spills, infrastructure failure or bio-terrorism. In these instances surveillance and mitigation planning are invaluable towards avoiding or lessening losses from these events.

It is estimated that most large companies spend between 2% and 4% of their IT budget on disaster recovery planning. The increasing dependence on IT systems, as well as increased awareness from large-scale disasters such as 9/11, contributed to the further growth of various disaster recovery related industries, from high-availability solutions to hot-site facilities.

However with advancement and development in technology related to disaster recovery, still there are no solid ways in which disaster can be prevented. Though it is difficult to stop natural disasters but its adverse effects can be avoided, provided efficient working as far disaster recovery is concerned.

The effects of disasters always last for a longer period of time and if the disaster occurred in a developing country like Pakistan then the consequences turned the situation into a horrible shape and end up in complete chaos.

If we take the example of 2005 Earthquake and very recent flood in Pakistan, and the ongoing terrorist activities, country has not fully recovered the loss of earthquake since 5 years had been passed, so it is very difficult to overcome the loss of recent floods so early .All this because of lack if disaster recovery strategies and their improper implementation.

Nevertheless, the consensus within the DR industry is that most enterprises are still ill-prepared for a disaster. According to the Disaster Recovery site, "Despite the number of very public disasters since 9/11, still only about 50 percent of companies report having a disaster recovery plan. Of those that do, nearly half have never tested their plan, which is tantamount to not having one at all."

As a result, preparation for continuation or recovery of systems needs to be taken very seriously. This involves a significant investment of time and money with the aim of ensuring minimal losses in the event of a disruptive event.
