HADR

HADR, or High Availability and Disaster Recovery, refers to strategies and systems designed to ensure that essential IT services remain operational or can quickly recover during outages or disasters. High Availability minimizes downtime through redundant systems and quick failover processes, keeping applications and data accessible. Disaster Recovery involves plans to restore systems and data after significant interruptions, such as natural disasters or cyberattacks. Together, HADR aims to maintain business continuity by protecting critical information and minimizing service disruptions, ensuring that organizations can quickly bounce back from unexpected events.
