An apparatus and a method for versioning a file of a file system is described. A versioning module stores multiple versions of the file. The file is opened for write access. The versioning module identifies an file mapping structure of a block associated with the file, copies the content of the file mapping structure of the file to a new file mapping structure of the file, and allocates a new block to the file as represented by the file mapping structure.
