Abstract:
Changes in a multi-RAID configuration to metadata of a source production volume in a source RAID are monitored since taking a most recent FC backup on the source production volume. The incremental copies of the metadata are stored on a target production volume in a target RAID. The source RAID is used to serve as a storage for the source production volume and also serve as a FC backup of the target production volume residing on the target RAID for creating a dual purpose for the multi-RAID configuration.
