Disaster Recovery

Definition

Disaster recovery (DR) is the set of policies, tools, and procedures enabling an organization to restore IT systems and data after a catastrophic failure — data center outage, data corruption, or ransomware. DR plans define RTO and RPO targets and choose between warm standby, cold standby, or active-active configurations to meet them within budget constraints.
