Disaster Recovery

High-Availability depends on how quickly you can recover a production system after an incident that has caused a failure. This requires planning and documenting a suitable DR Strategy for your organization. If you get a Disaster Recovery Plan wrong, it can make an incident into a catastrophe for the business which could bring a potential loss of revenue for your company.

 

The 24/7 business operation requires reliable and timely disaster recovery (DR) mechanisms for all components of these solutions, including the databases. In the event of a failure, service must be resumed within a very short period of time, with minimal or no data loss.But before you can generate that detailed recovery plan, we need to perform a risk assessment and/or business impact analysis to identify the IT services that support the organization’s critical business activities. Once this work is out of the way, you’re ready to move on to developing disaster recovery strategies,

 

The following are some of the general step required to develop and implement a plan.

Policy Statement (Goal of plan, reasons and resources Business Impact Analysis (how does a shutdown impact the business financially and otherwise) Identify Preventive Steps (can disaster be avoided by taking prudent steps) Recovery Strategies (how and what you will need to recover) Plan Development (Write plan and implement plan elements) Plan buy-in and testing (very important so that everyone knows the plan and knows what to do) Maintenance (continuous changes to reflect current situation)

Stages of a Disaster Recovery Plan


The goal of a DRP is to resume normal computing capabilities in as little time as possible. A typical DRP has several stages, including the following:

 

  • Understanding an organization’s activities and how all of its resources are interconnected.
  • Assessing an organization’s vulnerability in all areas, including operating procedures, physical space and equipment, data integrity and contingency planning.
  • Understanding how all levels of the organization would be affected in the event of a disaster.
  • Developing a short-term recovery plan.
  • Developing a long-term recovery plan, including how to return to normal business operations and prioritizing the order of functions that are resumed.
  • Testing and consistently maintaining and updating the plan as the business changes.
