Disaster recovery involves managing and re-establishing systems and infrastructures that are adversely affected by computing failures, natural disasters, and disruptive intentional attacks. This process involves regaining access and functionality of standard functionality.

These disruptions affect business operations, causing severe losses, and even impacting reputation. Thus, every organization should establish advanced cybersecurity approaches in order to prevent data breaches and ensure a secure recovery in case of data loss.

There are several types of disaster recovery, and they include:

• Backup: Backup entails storing data on a removable drive or offsite in a location that can be retrieved when needed.
• Hot site: A hot site keeps up-to-date copies of information and data, which is essential in lowering downtime.
• Cold site: A cold site is a disaster recovery site that sets up a basic organization of IT infrastructure for a given time as a facility for employees to work quickly after a natural disaster.
• Virtualization: Virtualization involves backing up an organization’s specific data pool, or an entire working replica of its computing environment, to offsite simulated machines unaffected by physical disasters.
• Point-in-time copies: Point-in-time copies take snapshots of the entire database at any given time. Backup-up data can be restored only if stored on a virtual machine or in an offsite location that cannot be affected by a natural or artificial disaster.
