摘要

A method and system for storing data files and retrieving data stored in a data file are provided. The method for storing includes receiving a first data file and a first data file virtualization policy; associating and then storing the first data file with the first data file virtualization policy on a storage device in communication with the computer system. The method of retrieving data includes receiving a request for at least a portion of the first data file, the request including a start of the at least a portion and a size of the at least a portion; computing a data offset that is aligned to an integer multiple of a block size of the storage device (Bsz) and nearest to the start of the portion; reading data within a byte-range that is a Bsz; and transmitting the portion starting at an offset relative to the data offset.
