Steps for Better Disaster Recovery
Data being the most important entity in today’s digital age, has organizations scuttling to have a better data recovery (DR) plan, the lack of which will inevitably result in failures and testing pitfalls. The first step for any good DR planning should ideally begin with business impact analysis. A business impact analysis should clearly define and categorize information systems as mission critical, business critical, or just business support. Most DR planning exercises require businesses to clarify the recovery point objective (RPO); the most critical questions to ask is where to store the recovery data, when to recover it, and how fast can it be restored after a disaster. While defining the recovery point and time there are other facts that organizations also need to take into consideration. Classifying data and prioritizing it for retention, retrieval, and archival is a crucial step, which is exactly what a business impact analysis defines. Setting the right expectations, choosing the right location, having the right tested DR plan with a proof of concept are also an important part of the strategy. Additionally, a structured documented approach to DR planning covering all details such as physical and logical architecture, dependencies (inter, and intra-application), interface mapping, authentication is a must.
In many ways, an organization’s functional DR plan looks to eliminate costly downtime and maintain their brand name. A well thought out and implemented DR plan, though painstaking, can prove to be a shield that protects enterprise digital assets against disasters and uncertainties.
