In data storage, disk mirroring (which is different from file shadowing) is the replication of logical disk volumes onto separate logical disk volumes in real time to ensure continuous availability, currency and accuracy. A mirrored volume is a complete and separate copy of a logical or physical disk volume. Disk mirroring can function as a Disaster Recovery solution by performing the mirroring remotely and over distance. Depending on the technologies used, mirroring can be performed Synchronously, Asynchronously, Semi-synchronously, or point-in-time.
