Tivoli Storage Manager for Windows Administrator's Guide


Putting It All Together

Figure 123 shows the relationship between TSM device, media, and policy objects. Together, these storage objects create a virtual model of the physical device environment. The model allows administrators to configure TSM to implement strategies and manage client data. The numbers in the following list correspond to the numbers in the figure.

(1)
Administrators register clients and associate them with a policy domain containing a policy set, management class, and copy groups. See Managing Nodes.

(2), (3)
When TSM backs up, archives, or migrates data, it is bound to a management class. A management class and the backup and archive copy groups within it specify where files are stored and how they are managed when they are backed up, archived, or migrated (space-managed files). See Client Migration and Recall.

(4), (5)
Storage pools are the destinations for backed-up, archived, or space-managed files. Copy groups specify storage pools for backed-up or archived files. Management classes specify storage pools for space-managed files.

Storage pools are mapped to device classes, which represent devices. The storage pool contains volumes as indicated by the device type associated with the device class. For example, a storage pool that is mapped to a device class with a device type of 8MM contains only 8mm tapes.

All devices require a device class that specifies at least a device type. Tape and other removable media devices also require a library and drive for management of media, including the mounting of that media.

(6)
Files that are initially stored on disk storage pools can migrate to tape or other types of storage pools if the pools are set up in a storage hierarchy.
