A local imager () copies each allocation unit () occupied by a file () of a file system () to a locally-stored image file () within the same partition () as the file system (). The allocation units () may be compressed as they are copied, resulting in a locally-stored image file () that occupies fewer allocation units () than the original file system (). In addition, the local imager () adds a directory map () to the locally-stored image file () that associates copied allocation units () in the locally-stored image file () with names of corresponding files () from the file system ().

Method and apparatus for localized protected imaging of a file system

A method and system for imaging data between two or more digital computers across a computer network is described, where the digital computers transfer data in a peer-to-peer mode and/or a client/server mode upon command of the operator. This invention address the problem of managing, updating and installing executable software, such as operating systems, utilities and application software packages on a large number of networked computer systems. By using this invention properly, a system operator can transfer data stored on a single computer system to all or some of the computer system connected to the first system over a computer network and can do so without expensive electronic server equipment. Moreover, this invention provides the capability of transferring data as files, sectors or cylinders of disk media, thereby permitting a single operator to, through a generally automated procedure, simultaneously install new system software, configuration files and executive files on many computers. This invention provides an important improvement in the operation, maintenance and control of large computer networks, although it applies and works equally well in small network applications. In its best mode of operation this invention is performed on standard digital computer systems through the use of special purpose computer software.

Method and system for client/server and peer-to-peer disk imaging

A method, implemented as a computer program in a digital computer system, for interrupting, modifying and/or controlling the boot process of a computer, automatically (without manual intervention) across a computer network. When a network manager needs to install software, test, maintain or gather information concerning one or more of the computer systems on the network, this invention permits the network manager to take control of the networked computer during its boot process, and in so doing to reconfigure both the networked computer's hardware and software, and to do so remotely. When fully implemented an entire network may be automatically controlled and tested remotely, all networked computers simultaneously or in sequence. An important improvement over methods of modifying the boot process which require manual intervention on individual computers or which require the use of expensive special purpose hardware devices which must be installed within each networked computer. In the best mode of operation, the method of this invention is performed on standard digital computer hardware through the use of special computer programs.
