摘要

Provided are methods and system for storing data files and retrieving data stored in a data file. The method of storing includes: receiving a first data file and a first data file virtualization policy line; 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 having a start of the at least one portion and a size of the at least one portion; Calculating a data offset that is equal to an integer multiple of a block size of the memory device (Bsz) and closest to the start of the part; Reading data within a byte range that is a Bsz; and transmitting the part that starts relative to the data offset at an offset position.
