    Publication number: 20190129806
    Abstract: The invention introduces an apparatus for a file backup, at least including a processing unit and a storage device. The processing unit divides a source stream into a first and a second data streams according to last-modified information, performs a data deduplication procedure on the first data stream to generate and store unique chunks in the storage device and generate a first part of a first set of composition indices for the first data stream; copies composition indices corresponding to logical locations of the second data stream from a second set of composition indices for a previous version of the source stream as a second part of the first set of composition indices; combines the first and second parts of the first set of composition indices according to logical locations of the source stream; and stores the first set of composition indices in the storage device.
