Disaster recovery (DR) is the discipline of preparing for, responding to, and recovering from disruptive incidents that threaten IT systems and business operations. In modern DevOps and cloud-native environments, DR is not just about backups—it’s about designing resilient architectures, automating failover, and validating recovery procedures to minimize downtime and data loss.
Effective disaster recovery planning addresses both technical and organizational risks. It defines Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO), implements automated backup and restore workflows, and ensures that failover processes are tested and documented. DR is essential for regulated industries, mission-critical workloads, and any team operating in the cloud or with distributed systems.
