Abstract: The invention discloses a multi-version control method for data documents, and a device thereof. The method comprises generating data-block fingerprints for all data blocks of a benchmark version; determining common data contents common between a newer version and the benchmark version according to the data-block fingerprints, and indexing the common data contents; determining the data contents peculiar to the newer version, i.e. not contained in the benchmark version according to the indexes, and indexing these particular data contents; determining positions of these data contents in the newer version according to the indexes; determining the data blocks with identical data contents between the two versions through the comparisons of data-block fingerprints and data contents; extracting the data contents common between the two versions, the data contents peculiar to the newer version, as well as the positions of the data contents in the newer version.
