  • Systems and methods for managing snapshots of replicated databases
    Patent number: 8666942
    Abstract: Systems and methods for managing copies of database data. For instance, in one configuration, prior to the database transactions being committed on either of the source data base and the target database, a first copy of the database can be stored on a target system. Subsequent to said generating the first copy, the data transactions are committed into the target database, and a second copy of the target database is created. Then the target database can be reverted back to a state in which the target database existed at the time of said generating the first copy. The second copy can be accessed without the use of the database application.

  • Systems and methods for resynchronizing information
    Patent number: 8655850
    Abstract: Methods and systems for synchronizing data files in a storage network between a first and a second storage device is provided. The method includes storing first data files associated with the first storage device to a storage medium, whereby the first data files include first data records. The storage medium may then be transferred to the second storage device. The first data files from the storage medium may be loaded onto the second storage device. The second data records from the first storage device may be received, and the first and second data records are compared. The first data files at the second storage device may be updated based on the comparison of the first and second data records.

  • COLLABORATIVE RESTORE IN A NETWORKED STORAGE SYSTEM
    Publication number: 20130346373
    Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During restore operations, the system can use the client-side signature repository to identify data blocks located in primary storage. The system can also use the client-side signature repository to identify multiple locations within primary storage where instances of some of the data blocks to be restored are located. Accordingly, during a restore operation of one client computing device, the system can source a data block to be restored to the client computing device from another client computing device that is in primary storage.

  • INTELLIGENT DATA SOURCING IN A NETWORKED STORAGE SYSTEM
    Publication number: 20130339390
    Abstract: A storage system according to certain embodiments includes a repository of client-side data block signature information representative of a set of data blocks stored in a primary storage subsystem. In some cases, the system sources data blocks for secondary copy and restore operations from the primary storage subsystem instead of the secondary storage subsystem. Where multiple primary storage components (e.g., multiple client computing devices) contain copies of a data blocks involved in a secondary copy or restore operation, the system can decide which client to source the data block from based on sourcing criteria.

  • COLLABORATIVE BACKUP IN A NETWORKED STORAGE SYSTEM
    Publication number: 20130339298
    Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During copy or backup operations, the system can use the client-side signature repository to identify data blocks located in primary storage that are new or that have changed. The system can also use the client-side signature repository to identify multiple locations within primary storage where different instances of the data blocks are located. Accordingly, during a copy or backup operation of one client computing device, the system can source a data block that is to be copied to secondary storage from another client computing device that includes a second instance of the data block.

  • DEDICATED CLIENT-SIDE SIGNATURE GENERATOR IN A NETWORKED STORAGE SYSTEM
    Publication number: 20130339300
    Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During storage operations of a client, the system can generate signatures corresponding to data blocks that are being stored in primary storage. The system can store the generated signatures in the client-side signature repository along with information regarding the location of the corresponding data block within primary storage. As additional instances of the data block are stored in primary storage, the system can store the location of the additional instances in the client-side signature repository.

  • Systems and methods for classifying and transferring information in a storage network
    Patent number: 8612714
    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.

  • SYSTEMS AND METHODS FOR ANALYZING SNAPSHOTS
    Publication number: 20130246360
    Abstract: This application describes techniques for creating a second snapshot of a first snapshot of a set of data, modifying the first snapshot, and reverting the modifications to the first snapshot. For example, portions of one or more transaction logs may be played into a database to put the database in a particular state a particular point in time. The second snapshot may then be used to revert to a prior state of the database such that additional transaction logs may be played into the database. These techniques enable the ability to put the database into multiple states as the database existed at multiple points in time. Therefore, data can be recovered from the database as the data existed at different points in time. Moreover, individual data objects in the database can be accessed and analyzed as the individual data objects existed at different points in time.

  • SNAPSHOT STORAGE AND MANAGEMENT SYSTEM WITH INDEXING AND USER INTERFACE
    Publication number: 20130238872
    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.
