Application clients can receive data, or named objects and their associated data, from TSM storage by using the restore and retrieve functions of the product. The restore function accesses objects that previously were backed up, and the retrieve function accesses objects that previously were archived.
Both restore and retrieve functions start with a query operation. The query returns different information depending on whether the data was originally backed up or archived. For instance, a query on backup objects returns information on whether an object is active or inactive, while a query on archive objects returns information such as object descriptions. Both queries return object IDs that TSM uses to uniquely identify the object on the server.
