1. A method of managing backup data, the method comprising:
accessing, via a backup manager, index data of an initial snapshot; accessing, via the backup manager, index data of a subsequent snapshot; determining, via the backup manager, whether the index data of the subsequent snapshot is different from the index data of the initial snapshot; responsive to a determination that the index data of the subsequent snapshot is different from the index data of the initial snapshot, creating an updated index data; creating an updated snapshot with the updated index data, wherein the index data and the updated index data comprise object identifiers and location identifiers; assigning objectstore identifiers to the object identifiers, wherein the object identifiers corresponding to data sets are further identified by the objectstore identifiers; and wherein the updated index data correspond to an updated data set within the updated snapshot.
