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. It helps to avoid failed backups
due to missing (free) media.

When is a free pool used?

Media are moved between regular and free pools on two events (

Figure

36

on page 138):

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 done automatically. Media from the
PC backup pool in

Figure 36

on page 138, for example, are not automatically

deallocated.

Protected (allocated, used) media belong to a specific regular pool (like the 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 for all pools that are configured
to use this free pool.

Some regular pools, for example the Private pool in

Figure 36

on page 138, can also

be configured not to share any media with free pools.
