Abstract: A system (10) for virtual disks version control includes a selectively read-only volume (12); at least one topmost overlay (141, 142, 143, 144, 145); and at least two intermediate, selectively read-only overlays (16, 16?, 16?, 16??) configured as at least two mounting points. The at least one topmost overlay (141, 142, 143, 144, 145) is configured to store the results of redirected write operations. One of the at least two mounting points (16, 16?, 16?, 16??) and the volume (12) form an image, and the other of the at least two mounting points (16, 16?, 16?, 16??) and the volume (12) form another image. The at least two intermediate overlays (16, 16?, 16?, 16??) are operatively located between the volume (12) and the at least one topmost overlay (141, 142, 143, 144, 145).

Abstract: Exemplary embodiments of the present invention disclosed herein relate to a method and system for providing data in response to a request. An exemplary method comprises receiving a request for data and determining whether the request contains a specific pattern of data intended to enable a patching process. The exemplary method further comprises providing a response containing patched data if the request contains the specific pattern of data and providing a response containing un-patched data if the request does not contain the specific pattern of data.

Abstract: A data processing network has a virtual hard drive emulator and client terminals that share a virtual disk image. Client-specific read-write versions of selected files or directories are supported. All clients access the client-specific versions using the same name and address identifiers (for example, the same file name for a given configuration file), but each client has an exclusive version. A file ID distinguishes respective clients. These files are maintained alongside other files of other types and attributes. The selection of files to be client-specific can be predetermined, or a client-specific version of a file can be generated if the client executes a write operation to a client-specific file or area, the written data containing data read by the client in any of memory area available to the clients (RAM, Virtual Disk Drive, Hard Disk drive etc.). The technique supports customization while maximizing administrative control of operating system versions and minimizing redundant storage.
