摘要:
Disclosed is a data recovery mechanism associated with a data writing process in a storage area network (SAN). In general, a data writing mechanism is provided so that a particular host can write data to a storage device in a particular SAN session. One specific example of a data writing mechanism is a data tapping mechanism that provides a copy of this data to an appliance. The data recovery mechanism allows the appliance to recover data from the particular target, for example, when the data was unsuccessfully mirrored to the appliance during the data tapping or when the appliance needs to obtain the data that was written prior to a data tapping procedure being initiated. In one embodiment, the data recovery mechanism is set up so that the appliance can recover data from the target by mimicking the particular host.
