Abstract
Lun clones are transferred from a primary server to a secondary server. The lun clones on the secondary server maintain the same data storage space saving relationship with backing luns of the lun clones as exists on the primary server. Incremental backups and restores of the lun clones between the primary and secondary servers involves transferring less than the total number of data blocks associated with the lun clone.
