A method, system, computer-readable medium, and computer system to perform operations on selected data in a storage area. Storage locations in the storage area can be identified by a requester for performing an operation only on the data in the identified storage locations. The requester can be an application managing the data (such as a database application, file system, or user application program) or a storage manager. The storage locations containing the data are obtained by software performing the operation, which can be a storage manager or an application operating in conjunction with a storage manager, such as a storage area replication facility. The software performing the operation operates only upon the identified locations, thereby affecting only the data stored within the identified locations. The requester can specify the operation to be performed as well as entities having permission to perform the operation on specified subsets of the storage locations. |
