  • Patent number: 7660807
    Abstract: Systems and methods for managing electronic data are disclosed. Various data management operations can be performed based on a metabase formed from metadata. Such metadata can be identified from an index of data interactions generated by a journaling module, and obtained from their associated data objects stored in one or more storage devices. In various embodiments, such processing of the index and storing of the metadata can facilitate, for example, enhanced data management operations, enhanced data identification operations, enhanced storage operations, data classification for organizing and storing the metadata, cataloging of metadata for the stored metadata, and/or user interfaces for managing data. In various embodiments, the metabase can be configured in different ways. For example, the metabase can be stored separately from the data objects so as to allow obtaining of information about the data objects without accessing the data objects or a data structure used by a file system.

  • Patent number: 7651593
    Abstract: Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

  • Publication number: 20090307449
    Abstract: A system and method of managing stored data in a storage management system. The storage management system includes a storage manager, a media agent connected to the storage manager, and a primary volume connected to the media agent. A plurality of snapshots are taken of the primary volume. The snapshots are indexed by associating respective information with the snapshot. The indexed snapshots are copied to a recovery volume. In this way, browsing features are enabled for the user. The user may view the snapshots in a hierarchical format, and may even view snapshot data in association with the corresponding application. The resultant recovery volume may be used to replace a primary volume.

  • Patent number: 7631151
    Abstract: Systems and methods for data classification to facilitate and improve data management within an enterprise are described. The disclosed systems and methods evaluate and define data management operations based on data characteristics rather than data location, among other things. Also provided are methods for generating a data structure of metadata that describes system data and storage operations. This data structure may be consulted to determine changes in system data rather than scanning the data files themselves.

  • Publication number: 20090221372
    Abstract: Described herein are games and game systems including a text messaging phone keypad foot mat. The phone keypad foot mat typically includes regions similar to the buttons of an enlarged telephone keypad. A user can step on these input regions (“buttons” or “keys”) to type a text. Thus, a player “types” a text message by stepping or dancing on the keyboard foot mat similar to the way that a text message may be typed by hand on a telephone keypad (e.g., sending a text message from a cell phone). Various games can be played using the devices, systems and methods described herein.

  • Publication number: 20090221337
    Abstract: A system and method are provided for a physically active game whose underlying purpose is to increase the level of physical activity in adolescents, and to have the game and associated activity be enjoyable and engaging such that physical activity becomes engrained as a habit that counters obesity. The game system includes a set of networked game modules that players touch in a sequence as prescribed by a game logic The correct module to touch next in the sequence is indicated by a notifier, such as a light turning on or an audible signal emitting from the module. Sensors on the modules transmit a signal to a controller which activates transmission of the next module in the sequence to activate a notifier element. Game data may be used to compute a score and be applied to game statistics. Data from the game may be transmitted to a remote server for storage, transformation into comparative data, and displayed on a web page.
