ABSTRACT:
Aspects of the invention provide for at least one first data portion of a first storage device in a system to be updated to a second storage and further replicating the update to a second data storage portion of the second storage device if a substantial system error fails to occur during the updating of the first data storage portion. Aspects can, for example, include facilitating restoration of a primary or secondary volume of a primary storage device or of a first or second secondary storage via secondary storage device copying, and/or alternative, alternating or internal/external application driven first and second (and/or further) secondary storage portion utilization. Aspects can also include state driven synchronization or re-synchronization of local and remote copies, or one or more of storage devices utilized can, for example, include a disk array.
