Abstract

An apparatus and method for mirroring data is provided wherein integrity of data on a mirror device is maintained during and after a restore process of data to a standard volume. Because integrity of the mirror is maintained, data from the mirror may be used to perform a later restore to the standard volume if data becomes corrupted, or data is unavailable for any other reason. As a result, the mirror may be used for backup or other operations.
