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.
