Protector Express catalog in one location. (See Catalog View on page 151.) Many commands can also be
executed from this view.
The Jobs and Media view displays media folders and media objects. You can use this view to work with
these catalog objects. For example, you can create and delete media folders, as well as create and delete
media objects, such as tapes. The Devices view, on the other hand, is used to perform physical operations
with the backup device. For example, media can be erased and formatted from the Devices view.
The difference between the Jobs and Media view and the Devices view is significant: the Jobs and
Media view is used to make changes to the catalog while the Devices view is used to perform operations
using the physical or virtual devices themselves (both media and drives). When you want to make
changes to the catalog, use the Jobs and Media view. When you want to work with the physical media or
with the device itself, use the Devices view. For example, if you want to change the name of a tape, you
make that change on the Jobs and Media view because you are making a change to the Data Protector
Express catalog. However, if you want to identify a tape by reading its header, you must use the Devices
view.
The Catalog view displays all of the objects in the current catalog. This may be useful, on the one hand,
because you will be able to see and work with all the catalog objects at once. On the other hand, because
all of the objects are displayed, it may be difficult to work with this view efficiently.
