Tivoli Storage Manager Using the Application Program Interface

Associating a Management Class With Objects

One of the primary features that TSM offers is the use of policy (management classes) to define how objects are stored and managed in TSM storage. A management class is associated with an object when the object is backed up or archived. This management class determines the following:

Management classes have two components, backup copy group, and an archive copy group. A copy group is a set of attributes that define the management policies for an object that is backed up or archived. If a backup operation is being performed, the attributes in the backup copy group apply. If an archive is being performed, the attributes in the archive copy group apply.

Because the use of policy is a very important component of TSM, the API requires all objects that are sent to the server first be assigned to a management class. There are two ways to do this.

Note:
The backup or archive copy group in a particular management class can be empty or NULL. If an object is bound to the NULL backup copy group, then that object cannot be backed up. If an object is bound to the NULL archive copy group, the object cannot be archived.
