How Backup Uses Pool Criteria to Sort Data

When you configure Backup, you can create additional pools and sort data by pool type and any combination of the following criteria:

• Group (backup group)

• Backup client

• Save sets (file or filesystems)

• Backup levels (full, levels 1 - 9, incremental, manual)

If you begin by entering a group name in the Group attribute, the pool is immediately restricted to accept only data associated with the named group. If you add a second group name to the Group attribute, the pool accepts data associated with either group, but no others. Entries for a single attribute function as "OR" clauses; that is, the pool accepts data from clients in either group.

Each of the four configuration criteria, however, functions with the others as an "AND" clause. That is, if you enter configuration criteria in both the Group attribute and Save Set attribute, only data that meets both the Group criteria and the Save Set criteria is written to volumes from the specified pool.

You cannot create pools that share identical settings for pool type, group, client, save set, or level. If the settings for a new pool match the settings for an existing pool, you receive a warning message. Change the appropriate settings and reapply to save the pool resource.
