  • Patent number: 9262275
    Abstract: A system for archiving data objects using secondary copies is disclosed. The system creates one or more secondary copies of primary copy data that contains multiple data objects. The system maintains a first data structure that tracks the data objects for which the system has created secondary copies and the locations of the secondary copies. To archive data objects in the primary copy data, the system identifies data objects to be archived, verifies that previously-created secondary copies of the identified data objects exist, and replaces the identified data objects with stubs. The system maintains a second data structure that both tracks the stubs and refers to the first data structure, thereby creating an association between the stubs and the locations of the secondary copies.

  • Patent number: 9262449
    Abstract: The automatic, tiered retention storage system according to certain aspects can automatically classify data items based on content, such as based on the inclusion of search terms in the data items, or based on metadata or other characteristics associated with the data. Based on the classification, the system can assign the data items to corresponding user-defined “buckets.” In some embodiments, each bucket is associated with a particular tier in the storage system having a specific retention period.

  • Patent number: 9208160
    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: 20150254254
    Abstract: Techniques for enabling user search of content stored in a file archive include providing a search interface comprising a search rules portion and an action rules portion, receiving a file archive search criterion comprising at least one search rule, and searching the file archive using the search criterion. The techniques also include generating a set of files filtered using the search criterion and performing an action specified in the action rules portion on a file included in the set of files.

  • Patent number: 9092500
    Abstract: A method and system for utilizing snapshots to provide copies of a database or other application or large data structure to computing devices receives a request for access to a copy of a database, and performs a snapshot of a storage volume containing the requested database. The system then clones the snapshot and mounts the snapshot to a computing device, thus enabling the computing device to access a copy of the database. In some examples, the system automatically updates copies of a database on a scheduled basis (e.g., daily or weekly basis) to refresh a database regularly.

  • Publication number: 20150205817
    Abstract: Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.

  • Publication number: 20150205682
    Abstract: In certain embodiments, a tiered storage system is disclosed that provides for failover protection during data backup operations. The system can provide for an index, or catalog, for identifying and enabling restoration of backup data located on a storage device. The system further maintains a set of transaction logs generated by media agent modules that identify metadata with respect to individual data chunks of a backup file on the storage device. A copy of the catalog and transaction logs can be stored at a location accessible by each of the media agent modules. In this manner, in case of a failure of one media agent module during backup, the transaction logs and existing catalog can be used by a second media agent module to resume the backup operation without requiring a restart of the backup process.

  • Publication number: 20140250093
    Abstract: Described in detail herein is a method of copying data of one or more virtual machines being hosted by one or more non-virtual machines. The method includes receiving an indication that specifies how to perform a copy of data of one or more virtual machines hosted by one or more virtual machine hosts. The method may include determining whether the one or more virtual machines are managed by a virtual machine manager that manages or facilitates management of the virtual machines. If so, the virtual machine manager is dynamically queried to automatically determine the virtual machines that it manages or that it facilitates management of. If not, a virtual machine host is dynamically queried to automatically determine the virtual machines that it hosts. The data of each virtual machine is then copied according to the specifications of the received indication.

  • Publication number: 20140229444
    Abstract: A method and system for creating secondary copies of data whose contents satisfy searches within data stores is described. In some cases, the system searches for data within a data store, identifies a set of data that satisfies the search, copies the identified set of data, and transfers the copy to secondary or other storage. In some cases, the system utilizes search-based secondary copies of days during restoration processes in order to restore data similar to and/or associated with data requested to be restored.
