Optimized reading of multiple objects from tape
Abstract:
A method for restoring multiple objects from tape (1) generates a list of objects to be restored from tape; (2) identifies a starting location of a first object on the tape; and reads, into a buffer from the tape, an entire buffer of data from the starting location. The method then (4) determines a length of the first object; (5) restores the first object; and (6) finds a start of a next object in the buffer using a length of the previous object. The method (7) determines a length of the next object by analyzing metadata of the next object and (8) restores the next object if the next object is in the list. The method (9) repeats steps (6), (7), and (8) until the end of the buffer is reached or all objects in the list have been restored. A corresponding system and computer program product are also disclosed.
