What is Disaster Recovery

Disaster planning, emergency preparedness, or business continuity (and experts note that there are differences) -  the goals are ultimately the same:  to get an organization back up and running in the event of an interruption.  The problem causing the interruption could be one computer crashing or an entire network crashing.  Or it could be an electrical outage or the result of a terrorist activity.  The goal is to have some contingency plans in the event of a problem.  A disaster recovery plan exists to preserve the organization so that it can continue to offer its services. 

A disaster recovery plan is a users' guide - the documentation - for how to preserve an organization.  In order for a plan to be useful, it must be created before an interruption occurs.  Business continuity is disaster recovery.  Lost revenue is a driving force in business continuity.  The reason to do a recovery plan is essentially to keep the funding coming in and the services going, and the clients being served.

• Emergency planning are those procedures and steps done immediately after an interruption to business.
• Disaster recovery are the steps taken to restore some functions so that some level of services can be offered.
• Business continuity is restoration planning, completing the full circle to get your organization back to where it was before an interruption.

In order to write your plan, you have to do some planning. This planning is the process that will get you to the step where you then commit your plan to paper - you can’t write a plan until you do the preparation.  The most difficult thing is getting started; the second most difficult task is keeping the plan current.

The Difference Between Disaster Recovery Planning and Business Continuity Planning Defined

Disaster Recovery Planning (DRP) is the process by which you resume business after a disruptive event.  This typically means that you can get the enterprise computers, networks, and data base operational. The event might be something huge-like an earthquake or the terrorist attacks on the World Trade Center-or something small, like malfunctioning software caused by a computer virus.

Given the human tendency to look on the bright side, many business executives are prone to ignoring "disaster recovery" because disaster seems an unlikely event. However Janco has found that over one third of all enterprises have had to activate their Disaster Plans in the last few years.

Business Continuity Planning (BCP) suggests a more comprehensive approach to making sure you can keep the enterprise going and meet it business objectives. This goes beyond the enterprise computers, networks and data bases.  However, the two terms are married under the acronym DR/BC or DRP/BCP. At any rate, Disaster Recovery Planning and/or Business Continuity Planning facilitate how a company will keep functioning after a disruptive event until its normal facilities are restored. 

Disaster Recovery Business Continuity Scope

Recognizing the scope of the requirements, Janco suggests that you purchase the Disaster Recovery Business Continuity Template  and the do the following:

• Conduct a business impact assessment. This involved a crossfunctional team to evaluate the business requirements and tier data based on the importance to our business operations.
• Protect data and applications. It was important to back up data frequently to ensure records are kept, so we needed to upgrade
  our backup equipment to a faster version to reduce the time it took to complete a backup cycle.
• Review power and connectivity options. We needed to add uninterrupted power supplies (UPS) and connectivity for critical servers, network connections and selected personal computers to keep the most essential applications running in case of a power outage.
• Document, test and update the disaster preparedness plan. Part of the Janco Disaster Recovery and Business Continuity Template plan needs you to include updated configuration diagrams of the hardware, software and network components to be used in the recovery. The plan also needed to include logistical details, such as travel to backup sites and spending authorization for emergency needs.
• Consider telecommunications alternatives. Often taken for granted, telecommunications backup involving redundancy and alternatives needed to be in place - and in the case of spot outages, redundancy may be enough. For larger outages, alternative communications vehicles, including wireless phones, wireless data cards and satellite phones, had to be considered.

Testing is Critical to Disaster Recovery Planning

Importance of testing is critical to the disaster recovery and business continuity planning.

All good disaster recovery and contingency plans start with having a good solid backup of data. Although systems and applications can be reinstalled and reconfigured, data cannot be rebuilt out of thin air. The key to having a good backup is to make sure the data is correct and can be successfully restored. This is not always as easy as it seems. One company had such an issue. Their backup administrator did not correctly follow procedures and when he thought he was doing a backup, he actually was not writing anything. When they tried to restore a database, they found out all the tapes were blank.
