TSM policy objects manage how data is stored, where client data is stored, the number of maintained versions, and the length of time those versions are stored.
TSM allows a variety of configurations using TSM policy objects, but regardless of the configuration, Teradata Extension for Tivoli Storage Manager requires a backup copy group policy object. The backup copy group policy object can be preexisting or newly-created, but only TSM backup object types are supported.
The following table lists TSM policy object fields that control the removal of inactive objects from storage. Objects become inactive when a backup is performed with the same name as an object that is already stored on the server.
See Overview of Backup Data Storage.
