on a volume means that the data can be restored, even if the primary volume
has been damaged or destroyed. For more information, see the Business Copy
manuals.
Continuous Access
Journal Software that asynchronously duplicates multiple volumes between storage
systems. Continuous Access Journal temporarily stores differential data on a
journal volume and then duplicates the data. Continuous Access Journal can
duplicate data on remote sites; it can also be used to create 3DC multi-target
and cascade configurations among multiple sites. For more information, see the
Continuous Access Journal manuals.
Continuous Access Software that duplicates volumes between storage systems. Continuous Access
duplicates all data on the volumes. Two types of Continuous Access are provided:
Continuous Access Synchronous, Continuous Access Asynchronous. For more
information, see the Continuous Access manuals.
Snapshot Software used to duplicate volumes in a single storage system. Snapshot
duplicates differential data in a data pool. The secondary volume is a virtual
volume that consists of the primary volume and the differential data. By duplicating
only the differential data, Snapshot can copy data in a very short time as well
as reduce the capacity required of the volume used for duplication. For more
information, see the Snapshot manuals.
