1. A method for accessing electronic data, the method comprising:
- storing electronic data that satisfies a first storage criteria to a first file location in a first storage device, the first storage device comprising a network attached storage device (NAS);
copying, according to a second storage criteria, the electronic data from the first file location to a second file location in a second storage device;
replacing the electronic data stored in the first location with a stub file;
retrieving, in response to a request to access the electronic data stored in the first file location, the electronic data stored in the second file location according to information contained in the stub file, wherein said retrieving comprises directly accessing the electronic data stored in the second file location without transferring the electronic data to the NAS;
modifying the electronic data and storing the modified electronic data in the second file location without transferring the electronic data or the modified electronic data to the first file location; and
updating the stub file in the first file location to reflect modifications made to the electronic data in the second file location without transferring the electronic data or the modified electronic data to the first file location.

Abstract
Systems and methods for performing hierarchical storage operations on electronic data in a computer network are provided. In one embodiment, the present invention may store electronic data from a network device to a network attached storage (NAS) device pursuant to certain storage criteria. The data stored on the NAS may be migrated to a secondary storage and a stub file having a pointer pointing to the secondary storage may be put at the location the data was previously stored on the NAS. The stub file may redirect the network device to the secondary storage if a read request for the data is received from the network device.
