Abstract: A method for designing a resilient organizational process includes determining a failure event, identifying one or more factors that the failure event is attributable to, analyzing the identified factors to determine a corrective process step for each factor, and mapping each of the corrective process steps to occupy a specific coordinate in a corrective action matrix. A first coordinate axis of the matrix represents organizational domains and a second coordinate axis of the matrix represents resilient system characteristics. The organizational domains include workplace, work and worker. The resilient system characteristics include anticipation, monitoring, responding and learning.

Abstract: A method for transporting an image file over a network is provided. The network may include two or more computers, and the image file may include a control stream, a data stream, and a cluster map stream. The method may include parsing the image file into two or more segments. A first segment may include the control stream, the cluster map stream and a first portion of the data stream. A second segment includes a second portion of the data stream. The method may also include sending the first segment from a first computer to a second computer, and sending the second segment from the first computer to the second computer.

Abstract: An image file format and a method of creating and restoring an image file is provided by the present invention. The image file format includes a plurality of streams such as a control stream, a data stream, a bitmap stream, and a cluster map stream. An audit trail stream, properties stream and fix-up stream may also be provided. The present invention allows the contents of a storage media to be captured and stored as an image file. The image file is used to restore the storage media to a previous state or allows multiple computers to be provided with a common configuration. The plurality of streams further allow the image file to be viewed, edited or otherwise manipulated.

Abstract: A system and method for probing a plurality of clients for a rate appropriate for multicasting is described. In one implementation, test data is sent by a server to a plurality of clients. A rate, Ri, based at least in part on a rate at which test data was received, is sent by at least some of the plurality of clients to the server. A rate, R0, at which an image is to be sent to the plurality of clients, is then calculated as a function of at least some of the Ri.

Abstract: A method and system for managing image files is provided. The image files include a plurality of streams such as a control stream, a data stream, a bitmap stream, and a cluster map stream. An audit trail stream, properties stream and fix-up stream may also be provided. An image driver translates requests from the operating system so that the image can be read, edited or otherwise manipulated.

Abstract: A system and method for encryption and decryption of files. The system and method operate in conjunction with the file system to transparently encrypt and decrypt files in using a public key-private key pair encryption scheme. When a user puts a file in an encrypted directory or encrypts a file, data writes to the disk for that file are encrypted with a random file encryption key generated from a random number and encrypted with the public key of a user and the public key of at least one recovery agent. The encrypted key information is stored with the file, whereby the user or a recovery agent can decrypt the file data using a private key. With a correct private key, encrypted reads are decrypted transparently by the file system and returned to the user. One or more selectable encryption and decryption algorithms may be provided via interchangeable cryptographic modules.

Abstract: A method and system that protects selected system and other files, by preventing changes to those files. In an asynchronous alternative, the change is prevented by copying back the original file when a protected file is changed, as known via an asynchronous notification. In an alternative synchronous embodiment, the change to the file is prevented from occurring. In the asynchronous notification alternative, a directory change notification notifies a file protection service whenever a file that has possibly changed is closed, providing the file identity as part of the notification. The file protection service determines from the file identify whether the file has been deemed protected. If protected, the file protection service prevents any actual change by verifying whether the protected file changed, such as by analyzing the file's contents against known valid contents. If not valid, the file protection service restores a saved copy that is itself verified.

Abstract: A method and system for recovering from a system failure wherein the failed system is restored to a new system that has different hardware. Hardware state is preserved during a backup process, and following a failure, a restore is performed to the extent possible using that hardware state but on a system having a different hardware configuration. Rules are provided for handling the differences through selective merging, arranging, and replacement of data, with the logic and work performed transparently to the user. Hardware state includes hard disk configuration information, the location (partition) of the operating system, devices installed on the system and any additional drivers to load. When restored, for hardware that is identical, the hardware state is restored as specified in the file. If the hardware state is not identical, then a set of rules are used to restore the hardware state.
