Abstract: According to certain aspects, an information management cell can include a failover storage manager configured to: instruct a secondary copy application to perform a secondary copy operation in which primary data generated by at least one client computing device is stored as a secondary copy in a second secondary copy file format different than a first secondary copy file format; and subsequent to reestablishment of connectivity to a main storage manager, restore the secondary copy stored in the second secondary copy file format to obtain restored data that is no longer in the second secondary copy file format; and can include at least one secondary storage computing device configured to, subsequent to the restore of the secondary copy, and at the direction of the main storage manager, conduct the restored data to a secondary storage device(s) to create a secondary copy in the first secondary copy file format.

Abstract: Indexing preferences generally associate each data source with a type of indexing technology and/or with an index/catalog and/or with a computing device that hosts the index/catalog for tracking backup data generated from the source data. Indexing preferences govern which index/catalog receives transaction logs for a given storage operation. Thus, indexing destinations are defined granularly and flexibly in reference to the source data. Load balancing without user intervention assures that the various index/catalogs are fairly distributed in the illustrative backup systems by autonomously initiating migration jobs. Criteria for initiating migration jobs are based on past usage and going-forward trends. An illustrative migration job re-associates data sources with a different destination media agent and/or index/catalog, including transferring some or all relevant transaction logs and/or indexing information from the old host to the new host.

Abstract: A method and system for reducing storage requirements and speeding up storage operations by reducing the storage of redundant data includes receiving a request that identifies one or more files or data objects to which to apply a storage operation. For each file or data object, the storage system determines if the file or data object contains data that matches another file or data object to which the storage operation was previously applied, based on awareness of the application that created the data object. If the data objects do not match, then the storage system performs the storage operation in a usual manner. However, if the data objects do match, then the storage system may avoid performing the storage operation with respect to the particular file or data object.

Abstract: Certain embodiments described herein relate to an improved selective data backup system. In some embodiments, one or more components in an information management system can determine that a portion of the primary data scheduled for backup was previously backed up or is scheduled to be backed up as part of another backup operation. For example, a data agent performing a cluster-level backup operation for an entire cluster of storage servers may check whether any part of the primary data was previously backed up by a prior server-level backup operation for one of the storage servers in the cluster. If so, the data agent may skip, in the cluster-level backup operation, any portion of the primary data stored in the storage server previously backed up as part of the prior server-level backup operation.

Abstract: Systems and methods for reconstructing unified data in an electronic storage network are provided which may include the identification and use of metadata stored centrally within the system. The metadata may be generated by a group of storage operation cells during storage operations within the network. The unified metadata is used to reconstruct data throughout the storage operation cells that may be missing, deleted or corrupt.

Abstract: An improved content indexing system is disclosed herein that content indexing system combines the functionality of the backup metadata database and the content index database into a single backup and content index database to avoid the need to perform synchronization operations. By using a single backup and content index database, the content indexing system also reduces the computing performance costs that would be associated with the synchronization operations as the amount of indexed content increases, thereby solving scalability issues.

Abstract: An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.
