Create a backup of a table that is to be moved to another data area after appropriate changes to CA Datacom Datadictionary definitions.
Create a backup of the data area that can be used in a future forward recovery operation if the data area becomes damaged.
Retrieve the data in a data area after the Index has become damaged.
