Putting It All Together

Figure 7 summarizes the relationships among the physical device environment, ADSM storage and policy objects, and ADSM clients. The numbers in the following list correspond to the numbers in the figure.

(1)

When clients are registered, they are associated with a policy domain. Within the policy domain are the policy set, management class, and copy groups.

(2), (3)

When a client backs up, archives, or migrates a file, 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 from a client (space-managed files).

(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 optical 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 optical disk storage pools if the pools are set up in a storage hierarchy.
