Geographic Disk Mirroring

A data recovery strategy that takes a set of physically disparate disks and synchronously mirrors them over high‐performance communication lines. Any write to a disk on one side will result in a write on the other side. The local write will not return until the acknowledgment of the remote write is successful.
