Abstract

See full text

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 an target RAID. An incremental FC backup of the metadata are periodically created or created if the monitored changes exceed a change rate threshold.
