Backup devices
Data Protector defines and models each device as a physical device with its own
usage properties, such as the default pool. This device concept is used because it
allows you to easily and flexibly configure devices and use them in conjunction with
backup specifications. The definition of the devices is stored in the Data Protector
Media Management Database.
Figure 12 How backup specifications, devices, and media pools are
related
Figure 12 on page 49 shows the relationship among the backup specification,
devices, and media pools. The devices are referred to in the backup specification.
Each device is linked to a media pool; this media pool can be changed in the backup
specification. For example, backup specification 2 references the pool Dept_X
instead of the default pool.
Data Protector supports various devices. For more information, see the HP Data
Protector product announcements, software notes, and references.
