  • Patent number: 8930306
    Abstract: A system and method for data deduplication is presented. Data received from one or more computing systems is deduplicated, and the results of the deduplication process stored in a reference table. A representative subset of the reference table is shared among a plurality of systems that utilize the data deduplication repository. This representative subset of the reference table can be used by the computing systems to deduplicate data locally before it is sent to the repository for storage. Likewise, it can be used to allow deduplicated data to be returned from the repository to the computing systems. In some cases, the representative subset can be a proper subset wherein a portion of the referenced table is identified shared among the computing systems to reduce bandwidth requirements for reference-table synchronization.

  • Publication number: 20140358935
    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: 8898411
    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. Multiple 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: 8886595
    Abstract: The present invention relates to a method for performing an image level copy of an information store. The present invention comprises performing a snapshot of an information store that indexes the contents of the information store, retrieving data associated with the contents of the information store from a file allocation table, copying the contents of the information store to a storage device based on the snapshot, and associating the retrieved data with the copied contents to provide file system information for the copied contents.

  • Publication number: 20140324772
    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.

  • Patent number: 8832406
    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: 20140181022
    Abstract: Systems and methods for replicating database data and generating read-only copies of the replicated data in a clean shutdown state. For example, systems can include a tracking module (e.g., a filter driver) that monitors transactions from a database application to a source storage device to generate log entries having at least one marker indicating a known good state of the application. The systems further include a computer coupled to a target storage device comprising a database and log files. The computer processes the transactions, based on the log entries, to replicate data to the target storage device; performs a first snapshot on data stored in the database and log files; replays into the database data stored in the log files; performs another snapshot on the database; and reverts the database back to a state in which the database existed at the time of the first snapshot.
