Abstract:
A data stream is stored in storage media. As part of the storage, the data stream is divided into a plurality of chunks. The plurality of chunks include a target chunk that is next to a first chunk in a file within the data stream. A determination is made that the target chunk matches an existing chunk stored in the storage media. In response to the determination, a first pointer to the existing stored chunk is created in file metadata for the file. Also in response to the determination, a second pointer to a first stored chunk that matches the first chunk is created in chunk metadata embedded with the existing stored chunk.

Claim (Index 12):
A computer program product for managing a file stored on storage media, the file including file data that is stored as a plurality of chunks on a first storage entity of the storage media, each stored chunk of the plurality of chunks including chunk metadata embedded therewith, the file further including file metadata that is stored on a second storage entity of the storage media, the computer program product comprising a computer readable storage medium, wherein the computer readable storage medium is not a transitory signal per se, the computer readable storage medium having program instructions embodied therewith, the programs instructions configured, when executed by at least one computer, to cause the at least one computer to perform a method comprising:\n detecting that the stored file metadata is lost or corrupted; and performing, in response to the detecting, a recovery operation, wherein the recovery operation comprises:\n reading chunk metadata embedded with a first stored chunk of the plurality of chunks; \n determining, based on the reading the chunk metadata embedded with the first stored chunk, that the first chunk does not have any preceding chunks in the file; \n identifying, based on the reading the chunk metadata embedded with the first stored chunk, a pointer to a second stored chunk; \n determining, based on the pointer, that the second chunk follows the first chunk in the file; and \n writing a recovered version of the file metadata in the second storage entity, wherein based on the determining that the first chunk does not have any preceding chunks in the file and further based on the determining that the second chunk follows the first chunk in the file, the recovered version of the file metadata indicates that the first chunk is the initial chunk of the file and the second chunk follows the initial chunk in the file.
