An architecture and system are described that provide a unified file access service within in a managed computing environment composed of diverse networks, computing devices, and storage devices. The service provides mechanisms for remotely accessing the file systems of any managed computer or disk snapshot, independently of the computer's current state (powered on, suspended or powered off), its location within the environment, its hardware type (virtual vs. physical), its operating system type, and its file system formats. The system isolates centralized FPAs from the details of clients, proxies and storage elements by providing a service that decomposes offloaded file system access into two steps. A FPA or a requester acting on behalf of the FPA first expresses the disk set or the computer containing the file systems it wishes to access, along with requirements and preferences about the access method. The service figures out an efficient data path satisfying the FPA's needs, and then automatically configures a set of storage and computing resources to provide the data path. The service then replies with information about the resources and instructions for using them. The FPA then accesses the requested file systems using the returned information.

1. A method of offloading file processing from client computers of a network, the method comprising: configuring a universal file access service to receive a request from a requester, wherein the request includes information directed to the offloading of processing of a specified file system and wherein the requester is one of a centralized file processing application for performing the processing or a subordinate application operating in conjunction with the file processing application;determining compatibility requirements for processing the file system in accordance with the request, including identifying compatibility requirements with respect to file formatting;in conformance with the compatibility requirements, utilizing the universal file access service to generate a temporary copy of one of the file system or the program of the file processing application; andexecuting the offloading of the processing using the temporary copy. 2. The method as described in claim 1 wherein said requester is a subordinate application operating in conjunction with a File Processing Application (FPA). 3. The method as described in claim 2 wherein said FPA and said subordinate application reside on different computer systems. 4. A method for performing offloaded file processing, the method comprising: accessing a request for services from a requester, said request comprising information from which a disk set is derived and a command involving said disk set;transparent to said requester, automatically determining volumes and file systems residing on said disk set;transparent to said requester, automatically determining volume formats and file system formats used by said volumes and file systems;transparent to said requester, automatically determining compatibility in accessing the file systems; andin connection with an offloaded file processing, executing said command comprising accessing said disk set using information obtained from said automatically determined volumes, file systems, volume formats, file system formats and client computer state. 5. The method as described in claim 4 wherein said requester is a File Processing Application (FPA). 6. The method as described in claim 4 further comprising, transparent to said requester, automatically determining a hardware type of said client computer and automatically determining a hardware type of said disk set. 7. The method as described in claim 6 wherein said hardware type is selected between physical and virtual. 8. The method as described in claim 4 wherein said request comprises an identifier familiar to said requester to identify said client computer and further comprising, transparent to said requester, automatically determining a network address of said client computer based on said identifier familiar to said requester. 9. The method as described in claim 8 wherein said identifier familiar to said requester is a hardware address. 10. The method as described in claim 9 wherein said identifier familiar to said requester is a host name provided by network software. 11. The method as described in claim 8 wherein said client computer is a virtual machine and wherein further said identifier familiar to said requester is a name of said virtual machine provided by software managing said virtual machine. 12. The method as described in claim 4 wherein said offloaded file processing is performed independent of a computer system and software stack of said requester. 13. A computer readable storage medium comprising instructions that when executed on a processor implement a method for performing offloaded file processing, said method comprising: accessing a request for services from a requester, said request comprising information from which a disk set is derived and a command involving said disk set;transparent to said requester, automatically determining volumes and file systems residing on said disk set;transparent to said requester, automatically determining volume formats and file system formats used by said volumes and file systems;transparent to said requester, automatically determining compatibility in accessing the file systems; andin connection with an offloaded file processing, executing said command comprising accessing said disk set using information obtained from said automatically determined volumes, file systems, volume formats, file system formats and client computer state. 14. A computer readable storage medium comprising instructions that when executed on a processor implement a method for performing offloaded file processing, said method comprising: a) accessing a request for services from a requester, said request comprising: information from which a disk set is derived; and a command involving said disk set, wherein said requester is a File Processing Application (FPA);b) transparent to said requester, automatically determining volumes and file systems residing on said disk set;c) transparent to said requester, automatically determining volume formats and file system formats used by said volumes and file systems;d) transparent to said requester, automatically determining existence and a state of a client computer associated with said disk set;e) transparent to said requester, automatically determining a hardware type of said client computer and automatically determining a hardware type of said disk set;f) transparent to said requester, automatically determining a network address of said client computer based on an identifier familiar to said requester;g) in connection with an offloaded file processing, executing said command comprising accessing said disk set using information obtained from said b)-f).
