What Is Disaster Recovery And How Does It Work?
Disaster recovery is the method that an organization uses for regaining functionality and access to its IT infrastructure after events like natural calamities, cyber-attack, or even business disruptions take place. Various disaster recovery (aka DR) methods can be part of a disaster recovery strategy. And in fact, DR is a crucial aspect of business continuity. In the continuing passages, we will be learning more about how disaster recovery works and others.
How Does Disaster Recovery Work?
Disaster recovery depends on the data replication and computer processing in an off-premises location not impacted by the disaster. When the server is down because of a natural disaster, or other problems like cyber-attack or equipment failures, a business needs to recover lost data from a second location that provides back up for the data. An organization can transfer its computer processing to that remote location and continue operations.
Key Aspects of an Effective Disaster Recovery Strategy
- Disaster Recovery Team: This allotted team of specialists will be accountable for developing, executing, and managing the disaster recovery program. This plan should describe the role and responsibilities of each team member. When a disaster takes place, the recovery group should know how to communicate with the employees, vendors, customers, and each other.
- Risk assessment: Evaluate potential risks that endanger your organization. As per the type of event, you need to determine what measures and resources you will require to resume business. For example, in the case of a cyber-attack, what type of data protection techniques should the recovery team have to respond to?
- Identification of Business-critical asset: A good disaster recovery plan comprises documentation of the systems, applications, data, and other resources that are most crucial for business continuity. Also, there are important steps for data recovery.
- Backups: Figure out the things that need backup or need to be relocated. Also, sort out the things that should perform backups and decide how backups should be executed. Add a recovery point objective (RPO) that defines the backup frequency. Also, include a recovery time objective (RTO) that describes the maximum amount of downtime permissible after a disaster.
These metrics create restrictions to guide the choice of IT strategy and procedures that develop an organization’s disaster recovery plan. The downtime an organization can manage and how frequently the organization backs up its data will notify the disaster recovery strategy.
Also, there is the part of testing and optimization. In this process, the recovery team consistently tests and updates its strategy for addressing ever-evolving risks and business requirements.
