Process for Information System Disaster Recovery: Roles & Aspects

Instructor: Vignesh Sivabalan

Viignesh has an MS in information technology.

Disaster recovery is an important phase in the business continuity plan for any organization. In this lesson, we will define disaster recovery and learn about the various teams involved. We will also discuss their responsibilities in carrying out recovery operations.

Disaster Recovery Defined

Disaster recovery (DR) consists of the policies, procedures and processes involved in restoring crucial business operations. These include recovery of workspace (desktop), communication (telephone and network), data access (software, hardware and databases) and other processes involved in business execution after a disaster.

The Importance of IT Disaster Recovery:

Many threats exist which can take down modern-day business operations. Some of these include:

  • Cyber attacks
  • Power outages
  • Equipment failure
  • Social engineering
  • Data decentralization
  • Fires
  • Virus and spam attacks
  • Employee negligence

It is critical to recover after a disaster in order to resume business (business continuance) with minimal loss. For example, if the data center of a company experiences a power outage, there is a need to recover quickly to meet the needs of demanding customers.

DR Participants, Responsibilities and Processes

Many teams take part in the disaster recovery process. Figure 1 outlines these teams. Each one is then described in greater detail.
