Abstract: The illustrative storage management system uses snapshot technologies and performs block-level analysis thereof and to synthesize full backups of a database, regardless of the database management system (DBMS) and content of the database and without involving native DBMS utilities. Synthetic full copies are created efficiently and use network transport resources sparingly. Successive snapshots of the database may be hardware snapshots and/or software snapshots. The illustrative storage management system tracks which data blocks in the database change over time after a baseline full copy is saved to secondary storage. Only the changed blocks are subsequently moved to secondary storage as incremental backups and are indexed for future reference. A synthetic full backup of the database, at a given point in time, may be created by synthesizing the original full backup with changed blocks from any number of later incremental backups. The synthetic full backup comprises pointers to appropriate data blocks, ignoring intermediate changes, and pointing to the most current data block in secondary storage relative to the given point in time chosen for the synthetic full backup. The illustrative storage management system may restore the synthetic full backup without native DBMS utilities.

Abstract: A data storage system according to certain aspects can share a single snapshot for multiple applications and/or agents. For example, the data storage system can receive snapshot commands from multiple applications and/or agents, and can group them for a single snapshot (e.g., based on time of receipt of the snapshot commands). Data associated with the multiple applications and/or agents may reside on a single LUN or volume. The data storage system can take a single snapshot of the LUN or volume, and generate metadata regarding which portion of the snapshot is related to which application. The single snapshot can be stored in one or more secondary storage devices. The single snapshot may be partitioned into portions relating to different applications and stored separately.

Abstract: Systems and methods are disclosed for speedily upgrading (e.g., via service packs) components of a storage management system, such as media agents and data agents, which may number in the thousands. The disclosed methods and systems provide a lightweight and flexible approach. Executable files such as service packs are deployed to a network-shared file system and are served on demand to each targeted host computing device to launch a data agent and/or media agent component. New service packs (e.g., upgrades) are installed on another shared drive and the connection thereto is refreshed by each targeted storage management component to begin executing the new version on demand. The resultant overall upgrade process across the storage management system may be substantially shortened, and the network burden greatly reduced.

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.

Abstract: An illustrative pseudo-file-system driver uses deduplication functionality and resources in a storage management system to provide an application and/or a virtual machine with access to a locally-stored file system. From the perspective of the application/virtual machine, the file system appears to be of virtually unlimited capacity. The pseudo-file-system driver instantiates the file system in primary storage, e.g., configured on a local disk. The application/virtual machine requires no configured settings or limits for the file system's storage capacity, and may thus treat the file system as “infinite.” The pseudo-file-system driver intercepts write requests and may use the deduplication infrastructure in the storage management system to offload excess data from local primary storage to deduplicated secondary storage, based on a deduplication database. The pseudo-file-system driver also intercepts read requests and in response may restore data from deduplicated secondary storage to primary storage, also based on the deduplication database.

Abstract: A data storage system includes a generic snapshot interface, allowing for integration with a wide variety of snapshot-capable storage devices. The generic interface can be a programming interface (e.g., an application programming interface [API]). Using the snapshot interface, storage device vendors can integrate their particular snapshot technology with the data storage system. For instance, the data storage system can access a shared library of functions (e.g., a dynamically linked library [DLL]) provided by the vendor (or another by appropriate entity) and that complies with the specifications of the common programming interface. And by invoking the appropriate functions in the library, the data storage system implements the snapshot operation on the storage device.
