Abstract
A method and system are provided for selectively deleting data stored to storage media, such as a tape, in a network storage system. An instruction to delete selected data is received and the location of the data selected for deletion is identified. The location of the data is obtained by consulting an index of storage data. The selected data is retrieved, together with any other data on the tape that precedes the selected data. The retrieved data, excluding the selected data, is copied to a tape. The index is updated to reflect the changes in the stored data on the tape.
