(1) In storage management, a policy object that users can bind to each file to specify how the server manages the file. The management class can contain a backup copy group, an archive copy group, and space management attributes. The copy groups determine how the server manages backup copies or archive copies of the file. The space management attributes determine whether the file is eligible to be migrated from the space manager client nodes to server storage and under what conditions the file is migrated.
(2) A user-defined schedule for moving objects from one storage class to the next. Management class describes the retention and class transition characteristics for a group of objects in a storage hierarchy.
