In an asynchronous remote copy system, a primary site keeps a list of data blocks for which changes have been made to a primary file system and transmitted to a secondary file system at a secondary site. When the primary site becomes inoperative, the secondary site begins read / write access to the secondary file system and keeps a snapshot copy of the restart point. Once the primary site becomes operative, the primary file system is restored to the state of the secondary file system at the restart point by using the list of data blocks for obtaining from the snapshot copy the data of the blocks for which changes had been made to the primary file system after the restart point. Then the primary file system is synchronized to the secondary file system, and read / write access is switched back from the secondary file system to the primary file system.

The system of the present invention comprises a personal Virtual Safety Deposit Box where users are able to enroll their identification methods, financial accounts and personal information. Once authenticated, this information is transferred to a master file within a central databank. Enrollment enables the user to link each item (collectively referred to as the “stored data”) to any one of the plurality of identification methods they enter. Thereafter, the user may employ their enrolled identification methods to select a desired one of the stored data fields. A secure intermediary uses the identification method and a selection method to determine which of the stored data fields the user desires to employ by accessing a database containing each of the stored data fields and the corresponding selection method. The selected field is activated and any relevant outside agencies are notified of the transaction and the transaction is concluded.

A system and method for rapidly identifying the existence and location of an item in a file using an improved hash table architecture. A hash table is constructed having a plurality of hash buckets, each identified by a primary hash key. Each hash entry in each hash bucket contains a pointer to a record in a master file, as well as a secondary hash key independent of the primary hash key. A search for a particular item is performed by identifying the appropriate hash bucket by obtaining a primary hash key for the search term. Individual hash entries within the hash bucket are checked for matches by comparing the stored secondary keys with the secondary key for the search term. Potentially matching records can be identified or ruled out without necessitating repeated reads of the master file. The improved hash table system and method is employed in a contextual text searching application for determining the intersection of a text search with a hierarchical categorization scheme.

A video-on-demand system provides efficient commercial distribution for renting and / or selling movies, video programs, video games and electronic data. Data input stations upload original video data from videotapes, videocassettes, videodisks or film, or from electronic data format on transferable storage media or over a telecommunications line. A video data capture computer converts the original video data into a preferred video data storage format and stores the video data files in a first generation video data storage unit. The video data files are sorted by categories and classified in indexed master files stored on a second generation video data storage unit. NTSC, PAL and / or HDTV versions of the video data files are created and stored in separate data storage units for serving different markets. Customers access the system through computer servers connected to the Internet. The computer servers access the video data file in the data storage units and create a temporary video data file, which is downloaded to the customer via the Internet. The video data file is downloaded at high speed and stored on the customer's video player device for viewing at a later time. The video data files can be downloaded, stored and viewed on a desktop computer, a laptop computer, palmtop computer, a set-top data storage device connected to a television set, video game device, or a personal digital assistant, cellular telephone or pager with video capabilities. The system includes back-up mirror storage files at all levels of the system for security against data loss.

In a computer system according to an embodiment of the present invention, a first slave server includes copy management information associating a master file system identifier with an identifier of a slave server including a copy of the master file system identified by the master file system identifier. The first slave server acquires a copy of a part of a master file system. The copy includes a stub-state object (file or directory). The first slave server searches the copy management information for a slave server to be queried regarding information for materializing the stub-state object. If the slave server to be queried includes the information for materialization, the first slave server materializes the stub-state object using the information for materialization acquired from the queried slave server.

The system and method realizes synchronization of files shared between master node and slave nodes on network, as well as reduces unnecessary file synchronization operation and prevents the condition of too large networked traffic needed by some synchronization operations.

The embodiment of the invention provides a file backup method and a main storage device. According to the file backup method, the storage space of a main file in the main storage device is divided into N secondary data blocks, at every backup moment of incremental backup, data in the updated secondary data blocks from the previous backup moment to the current backup moment are copied to a local backup buffer area, and at every backup moment of differential backup, data in the updated secondary data blocks from the initial backup moment to the current backup moment are copied to the local backup buffer area. Because the main storage device only needs to synchronize the data in the updated secondary data blocks stored in the local backup buffer area and the data in the secondary data blocks which are not updated do not need to be synchronized, the data size of file backup can be reduced, file backup efficiency is improved, and the storage space of the backup data is saved.

Described is a method and system by which storage reports are generated from a volume snapshot set rather than the live volume or volumes, wherein a volume snapshot set comprises a representation or copy of one or more volume at a single point-in-time. By scanning the snapshot, a consistent file system image is obtained. Scanning may take place by enumerating a volume's directories of files, or, when available, by accessing a file system metadata of file information (e.g., a master file table) separately maintained on the volume. With some (e.g., hardware-based) snapshot technologies, the snapshot can be transported to another computing system for scanning by that other computing system, thereby avoiding burdening a live system's resources when scanning. Accurate and consistent storage reports are thus obtained at a single point in time, independent of the number of volumes being scanned.

As such, in an aspect of the embodiment, the method further can include detecting an assistive technology, and rendering the visual markup language document in lieu of the slide show.

A method of correcting broken software links includes providing a computer data storage having target files and master files. Each master file includes a pointer to a storage location where at least one target file called by the master file resides. A link-id is determined for each target file and is stored in each master file configured to call the target file. The target file is then either renamed or moved so that each master file configured to call the target file cannot locate it from the pointer data. The target file is then located on the computer data storage based on a match between the link-id for the target file and the link-id stored in the calling master file. The data comprising the pointer of the master file is then updated whereupon it can locate the target file on the computer data storage.
