What is disaster recovery (DR) in storage?

Disaster recovery in storage is about preparing for and executing a plan to recover data and services after a major failure or the loss of a site. It involves defining how quickly you must recover (RTO) and how current the recovered data must be (RPO), setting up remote copies or backups, and regularly testing the recovery process so you can meet those goals. The goal is to restore operations and data quickly after a disaster, not just handle everyday data management. Duplicating data to reduce storage space, relocating data between racks, or encrypting data to prevent loss are separate activities—DR focuses on the end-to-end ability to resume services after a catastrophic event.
