The purpose of disaster recovery planning in IT is to establish processes and procedures that safeguard critical data and systems in the event of a disaster, such as natural disasters, cyber-attacks, or hardware failures. This planning involves assessing vulnerabilities, defining recovery objectives (e.g., recovery time objectives (RTO) and recovery point objectives (RPO)), and implementing appropriate backup and recovery solutions. By having a comprehensive disaster recovery plan, organizations can minimize downtime, protect sensitive information, and ensure business continuity, enabling them to recover quickly from unforeseen disruptions.
