Creating a Media Pool
What Is a Media
Pool? A media pool represents a set of media of the same type (for example
DLT) used for backup, with the same usage policy and properties. For
example, you may have one media pool for regular backup, one for
archive backup, and one for each department.
What Is a Free
Pool? A free pool is an auxiliary source of media of the same type (for example,
DLT) for use when all free media in a regular pool run out. This helps to
avoid failed backups due to unavailable media.
Media are moved between regular and free pools in two events:
• Allocation. Media are moved from a free pool to a regular pool.
• Deallocation. Media are moved from a regular pool to a free pool. You
can specify in the GUI whether deallocation is performed
automatically.
Protected (allocated, used) media belong to a specific regular pool (such
as a SAP pool), while free Data Protector media can be automatically
moved to a free pool. This free pool is later used for allocation of free
media to a specific regular pool during backup, when needed.
See the HP OpenView Storage Data Protector Concepts Guide for more
information on media pools.
Default Media
Pools Data Protector provides default media pools for each media type that you
can use in your initial configuration, for example: Default_DDS.
If you do not want to create a media pool at this time and to use the
default media pools instead, go to “Adding Media to a Media Pool” on
page 107 for instructions.
How to Create a
Media Pool Create a new media pool in the Devices & Media context using the Add
Media Pool wizard. For detailed steps, refer to the online Help index
keyword “adding media pools”.
What’s Next? The next step is to add media that you want to use for backup to the
media pool. See “Adding Media to a Media Pool” on page 107 for
instructions.
