Abstract: Replicated data storage units are autonomously identified and assembled into generationally related data storage volumes. A data storage manager, implementing a re-signaturing process executed at defined intervals or manually initiated on a server or client system connected to the storage area network, scans the collection of visible data storage units to identify those related as a data storage volume. Each replicated data storage unit includes metadata that embeds an identification of the replicated data storage unit and volume accessible to the data storage manager. To assemble a set of replicated data storage units into a generational volume, the data storage unit metadata is rewritten to establish a unique data storage volume identity including information to associate the data storage volume in a lineage with the source data storage volume.
