Paragraph Number

73

Typically, when an object request or group of object requests results in an object or data segment being modified, possibly during a read-modify-write operation, the object index module 266 updates an entry in the object index corresponding the modified object. In one embodiment, the object index creates a new object and a new entry in the object index for the modified object. Typically, where only a portion of an object is modified, the object includes modified data packets and some data packets that remain unchanged. In this case, the new entry includes a mapping to the unchanged data packets as where they were originally written and to the modified objects written to a new location.
