Plans and processes for restoring IT systems and data following a major disruption or disaster.
Disaster Recovery (DR) encompasses the policies, procedures, and technologies enabling recovery of critical IT systems and data after disasters—ransomware attacks, hardware failures, natural disasters, or facility loss. DR planning identifies critical systems, defines recovery priorities, establishes procedures, and ensures necessary resources are available. DR differs from backup—backup copies data; DR is the comprehensive plan for getting operations running again.
Why It Matters
The DSC Perspective:
Backup without DR planning is insufficient. You need tested procedures for actually recovering systems under pressure. DR planning answers: what gets recovered first, by whom, and how?
