Storing data files in a file system which provides reference data files

摘要

Data files are stored in a file system (10), wherein the file system (10) provides a plurality of reference data files (12), wherein each reference data file (12) represents a group of similar data files (14). The method comprises the steps of (i) creating a new data file (14); (ii) associating the new data file (14) with one reference data file (12) thus defining an associated reference data file (12) of the plurality of reference data files (12); (iii) informing the file system (10) about the association of the new data file (14) with the associated reference data file (12); (iv) compressing the new data file (11) using the associated reference data file (12); (v) storing the compressed data file (16) together with the information about the association with the associated reference data file (12). The invention can be applied to storing genomics data or seismic exploration data.
