Abstract: An information management system implements a media agent that communicates with a network area storage (NAS) device to receive secondary copy data that has been backed-up by the NAS. The secondary copy data may include primary data managed or maintained by the NAS. The secondary copy data may be in a proprietary format or other data format specific to the NAS. The NAS may prepare metadata or other information about the secondary copy data that informs the media agent as to the contents of the secondary copy data. The media agent may segment the secondary copy data into one or more backup chunks for storing in a secondary storage device. In addition, each of the backup chunks may be associated with backup chunk metadata, where the backup chunk metadata includes information that describes certain information stored by a corresponding backup chunk.
