A digital data file storage system is disclosed in which original data files to be stored are dispersed using some form of information dispersal algorithm into a number of file “slices” or subsets in such a manner that the data in each file share is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other file shares. These file shares are stored on separate digital data storage devices as a way of increasing privacy and security. As dispersed file shares are being transferred to or stored on a grid of distributed storage locations, various grid resources may become non-operational or may operate below at a less than optimal level. When dispersed file shares are being written to a dispersed storage grid which not available, the grid clients designates the dispersed data shares that could not be written at that time on a Rebuild List. In addition when grid resources already storing dispersed data become non-available, a process within the dispersed storage grid designates the dispersed data shares that need to be recreated on the Rebuild List. At other points in time a separate process reads the set of Rebuild Lists used to create the corresponding dispersed data and stores that data on available grid resources.

A system and method for searching information from a database using a natural language. In one embodiment, the system analyzes a natural language search request and converts the search request into one or more search words. The search words are further converted into a string of bytes, and a subset of a target database, referred to as the datasoup, is searched. If there is a match between the bytes and raw data in the datasoup, the searched data is retrieved from the target database. The searched data is then formatted and provided to a user. Optionally, the searched data can be provided to the user unformatted. In another embodiment, the system includes a system server configured to receive a natural language search request, a core engine coupled to the system server and to the target database, and a system database coupled to the core engine, where the core engine accesses the system database to analyze the search request. The system database stores global rules, one or more preference files, and one or more dictionaries, and the preference file stores information about the user.

Network data files are secure through the operation of an infrastructure gateway-based network file access appliance. Network file data, corresponding to network pocket payload data, are further reduced to a sequence of data blocks that are secured through any combination of block encryption, compression, and digital signatures. File meta-data, including encryption, compression and block-level digital signatures are persistently stored with the file data, either in-band in the file as stored or out-of-band key as a separately stored file or file policy record. File meta-data is recovered with accesses of the file data to support bidirectional encryption and compression and to detect tampering with the file data by comparison against block-level digital signatures.

This invention is related to content delivery systems and methods. In one aspect of the invention, a content provider controls a replacement process operating at an edge server. The edge server services content providers and has a data store for storing content associated with respective ones of the content providers. A content provider sets a replacement policy at the edge server that controls the movement of content associated with the content provider, into and out of the data store. In another aspect of the invention, a content delivery system includes a content server storing content files, an edge server having cache memory for storing content files, and a replacement policy module for managing content stored within the cache memory. The replacement policy module can store portions of the content files at the content server within the cache memory, as a function of a replacement policy set by a content owner.

Cookie files received from cookie file sources (e.g., Internet websites) are screened based upon the recommendations of a service provider which downloads privacy protection criteria in the form of a “watch list” to a subscriber's client machine. A user-friendly interface allows the subscriber to optionally modify the watch list prior to it being used at the subscriber's client machine by assigning known cookie file sources to either a “trustlist” or a “blacklist.” A “composite list” is then generated and used by the client machine to screen cookie files. The subscriber receives updates from the service provider on either a periodic or “as-needed” basis using a “quick update algorithm.” A “privacy scanning algorithm” runs on the client machine and has two different modes of operation. The first is a continuous mode where unwanted cookie files are blocked from being stored at the client machine. The second is a periodic mode where the client machine is “scrubbed” of unwanted cookie files according to the privacy protection criteria.

Data is now able to be transferred back and forth between computer systems which have disparate file systems, e.g., between a computer having a hierarchical file system and a computer having a nonhierarchical file system. The differences, however, are not limited to the file storage system. Data may now be transferred across different platforms, different human and computer languages, different binary codes, etc. From one computer system the associated metadata is stored in a interpretable format on the second computer system so that when data and its associated metadata are transferred, the second computer system can interpret the transferred data. Data transfer can be accomplished in both directions. Thus, a tool writer or a software developer using a integrated development environment, such as Eclipse, on a Linux workstation with its hierarchical file system may download source files and other resources from an iSeries computer server with its OS/400 nonhierarchical file system, modify the resources, and then put them back onto the iSeries machine for use on the iSeries. The metadata of the source file and other resources are stored in a .properties file which, if in XML format, supports the transfer of resources across the Internet.

A multi-user file storage service and system enables each user of a user group to operate an arbitrary client node at an arbitrary geographic location to communicate with a remote file server node via a wide area network. More than one user of the user group is permitted to access the file group at the remote file server node simultaneously, but the integrity of the files is maintained by controlling access so that each access to one of the files at the remote file server is performed, if at all, on a respective portion of that file as most recently updated at the remote file server node.

A system for scheduling time intervals for a plurality of users comprises a database associated with one or more server means for storing a profile for each potential invitee of the system. Each invitee profile comprises user profiles that have information regarding available and unavailable times for that user and the electronic mail address for the user and resource profiles having information about the available times for a particular resource such as a room or equipment. A request generator connected over a network to the one or more server generates a request for allocation of a time interval for one or more of the plurality of invitees. The system then provides a busy time determination device that gathers the profiles for the plurality of invitees that were requested by the request generating means and that are available in the databases and determines whether those invitees are available during the time interval requested by the request generating means. For all available invitees, the electronic mail address in the profile is used to send each available requested invitee an invitation to attend at the requested time interval.

A file storage system for storing data of a file received from a client includes a back-end file server in which the data is stored. The system includes a cache appliance in communication with the file server, such that the appliance stores portions of the data or attributes of the file, and uses the stored data or attributes to process file system requests received from the client, and which reads and writes data and attributes to the back-end file server independently. A system for responding to a file system protocol request in regard to a back-end server includes a token server. The system includes a plurality of cache appliances in communication with the token server, each of which receives tokens from the token server to synchronize access to data and attributes caches of the cache appliances, and reading and writing data and attributes to the back-end servers when tokens are revoked, the cache appliance having persistent storage in which data are stored, and the token server having persistent storage in which tokens are stored. A storage system includes a plurality of backend servers. The system includes a token server which grants permission to read and write file attributes and data system, and includes a plurality of cache appliances in communication with at least one of the backend servers and the token server for processing an incoming NFS request to the one backend server. Each cache appliance comprises an NFS server which converts incoming NFS requests into cache manager operations; a token client module in communication with the token server having a cache of tokens obtained from the token server; a cache manager that caches data and attributes and uses tokens from the token client module to ensure that the cached data or attributes are the most recent data or attributes, and an NFS client which sends outgoing NFS requests to the back-end file server. Methods for storing data of a file received from a client.

Data access time in content delivery networks is improved by storing files in cache servers as file bundles. A cache server determines that multiple files are requested by the same client based on information available in the request including the IP address of the client, a URL of a webpage referring to the file, and/or a cookie stored at a client. The cache server stores multiple files requested by the same client on the hard drive as a file bundle with meta data associating the files with one another, such that they can be accessed together. A future request from the client for a file in a file bundle results in multiple files from the file bundle being loaded in the memory. If the client requests another file from the file bundle, the file is accessed directly from the memory instead of the hard drive, resulting in improved performance.

Methods and systems for vendor independent and secure cloud storage distribution and aggregation are provided. According to one embodiment, an application programming interface (API) is provided by a cloud storage gateway device logically interposed between third-party cloud storage platforms and users of an enterprise. The API facilitates storing of files, issuing of search requests against the files and retrieval of content of the files. A file storage policy is assigned to each user, which defines access rights, storage diversity requirements and a type of encryption to be applied to files. Responsive to receiving a request to store a file, (i) searchable encrypted data is created relating to content and/or metadata of the file based on the assigned file storage policy; and (ii) the searchable encrypted data is distributed among the third-party cloud storage platforms based on the storage diversity requirements defined by the assigned file storage policy.
