1. A method for managing the storage of electronic data, the method comprising:
- storing a first copy of files at a first storage location associated with a network storage device (“
NAS device”
), wherein the NAS device has an internal operating system and an internal file management system, and wherein the NAS device communicates with other devices via a network;
tracking the first copy of the files stored in the NAS device with a data migrator that is external to the NAS device, wherein the data migrator executes on one or more computer processors that are externally located from the NAS device, wherein the data migrator also has a different file management system than the NAS device and maintains index data in a location external to the NAS device that comprises information about the first storage location associated with the NAS device;
processing at least one storage policy with the data migrator to determine when to copy the first copy of the files on the NAS device to one or more secondary storage devices;
using the index data to identify that the first copy of the files is stored in the first storage location associated with the NAS device; and
migrating, with the data migrator, the first copy of the files stored in the first storage location associated with the NAS device to a second storage location in one or more secondary storage devices externally located from the NAS device.

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.

10. A system for managing the storage of electronic data, the system comprising:
-
a network storage device (“
NAS device”
) that stores a first copy of files at a first storage location associated with the NAS device, wherein the NAS device has an internal operating system and an internal file management system, and wherein the NAS device communicates with other devices via a network;index data stored in a location external to the NAS device, the index data including information about the first storage location; and a data migrator executing in one or more computer processors, wherein the data migrator is externally located with respect to the NAS device and has a different file management system than the NAS device, wherein the data migrator maintains the index data, and wherein the data migrator is further configured to; track the first copy of the files stored in the first storage location associated with the NAS device; process at least one storage policy to determine when to copy the first copy of the files in the first location associated with the NAS device to a second storage location in a secondary storage device externally located from the NAS device; use the index data to determine that the first copy of the files is stored in the first storage location associated with the NAS device; and migrate the first copy of the files from the first location to the second location. - View Dependent Claims (11, 12, 13, 14, 15, 16)
