    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.

    Abstract: Described in detail herein are systems and methods for managing connections in a data storage system. For example, the systems and methods may be used to manage connections between two or more computing devices for purposes of performing storage operations on the data of one of the computing devices. The data storage system includes at least two computing devices. A first computing device includes an unauthorized connection data structure and a connection manager component. The connection manager component receives a connection request from a second computing device. If the second computing device is not identified on the unauthorized connection data structure, the connection manager component can request that an authentication manager authenticate the second computing device and/or determine whether the second computing device is properly authorized. If so, the connection manager component can allow the second computing device to connect to the first computing device.

    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.

    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.

    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.
