Managing Backup Policies (Classes)

• For schedules that can use the Tape Stacker 8MM, clear Override Class
Storage Unit. When these schedules run, NetBackup uses a Tape Stacker
8MM.
• For the schedule that requires DLT, select Override Class Storage Unit and
select Tape Library DLT. When this schedule runs, NetBackup overrides the
class default and uses the DLT library.
Notes on Specifying a Storage Unit
• If your site has only one storage unit or there is no specific preference for
storage, specify Any Available for the class storage unit and do not specify
a storage unit at the schedule level.
When you specify Any Available for the class storage unit and do not
specify one at the schedule level, ensure that at least one storage unit is
configured to be not on demand only. Otherwise, NetBackup will be unable
to find a storage unit for the backups.
• If you designate a specific storage unit and it is not available (for example,
because it is down for maintenance), backups will not run for classes and
schedules that require the storage unit.
• If your NetBackup configuration has several storage units and you want a
class to use more than one but not all of the storage units, perform the
following:
• When you configure volumes in Media Manager, define a volume pool
and volumes that only the desired storage units can access.
• For the specific class, set Class Volume Pool to the volume pool that only
the desired storage units can access.
• For all classes, set Class Storage Unit to Any Available.
Class Volume Pool
Specifies the default volume pool for backups of this class and NetBackup uses
it for all schedules that do not specify another volume pool. A schedule-level
volume pool (when specified) overrides the class default (explained later under
“Override Class Volume Pool” on page 107). If you do not name a volume pool
for either the class or the schedule, NetBackup uses the “NetBackup” pool.
