Abstract: According to certain aspects, a system may include a data agent configured to: process a database file residing on a primary storage device(s) to identify a subset of data in the database file for archiving, the database file generated by a database application; and extract the subset of the data from the database file and store the subset of the data in an archive file on the primary storage device(s) as a plurality of blocks having a common size; and at least one secondary storage controller computer configured to, as part of a secondary copy operation in which the archive file is copied to a secondary storage device(s): copy the plurality of blocks to the secondary storage devices to create a secondary copy of the archive file; and create a table that provides a mapping between the copied plurality of blocks and corresponding locations in the secondary storage device(s).

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 system according to certain aspects improves the process of data restoration and application recovery operations. The system can back up primary data based on network path information associated with a client computing device. When the primary data becomes corrupted or unavailable, a previously backed up copy of the primary data may be used as the primary data to achieve instant application recovery. For example, when a portion of the primary data is requested by a user or an application, the system may identify a corresponding portion in the backed up copy of the primary data and provide the identified portion to the user or the application in a manner transparent to the user or the application. Alternatively, the application running on the client computing device may send a request for the backup copy of the primary data to the secondary storage device upon determining that the requested data is not available.

Abstract: According to certain aspects, a system may include a computing device configured to: intercept a request from a database application to read a portion of a database file, where a secondary copy of the database file resides on a secondary storage device(s) and is organized as a plurality of first blocks, wherein the request includes a database file offset(s) corresponding to the requested portion; and map the database file offset(s) to a subset of the first blocks that correspond to requested database object(s). The system may include a secondary storage controller computer(s) configured to: access a table that maps the plurality of first blocks to storage locations on the secondary storage device(s); using the table, locate and retrieve the subset of the first blocks on the secondary storage device(s); and forward the retrieved first blocks for storage in a primary storage device(s).

Abstract: In certain systems disclosed herein, a distributed data monitoring and management system is provided that can replicate a distributed storage environment. The distributed data monitoring and management system can intelligently and automatically configure data access nodes to form a structure that matches the distributed storage environment. By matching the structure of the distributed storage environment, the distributed structure of the data may be maintained, enabling the data to be backed up from and/or restored to the distributed storage environment and/or migrated to another distributed storage environment without altering the distribution of the data. Further, embodiments herein enable the transfer of data from a non-distributed environment to a distributed storage environment. Thus, in some cases, an entity can migrate data from a local storage structure to a network-based distributed storage structure.

Abstract: An illustrative “Live Synchronization” feature creates and maintains a ready standby “synchronized application” that is available to take over as a failover solution for a “primary” application that operates in a production environment, but will do so on a different computing platform (e.g., physical server, virtual machine, container, etc.), and possibly on a differed kind of computing platform than, the primary. The illustrative system has specialized features and components for discovering and singling out each primary application and identifying and locating its disk image, e.g., VMDK file. The application is Live Synched to the standby/failover application without reference to whether and how other co-resident applications might be treated. The standby/failover destination supporting the synchronized application may be located anywhere, whether in the same data center as the primary or geographically remote or in a private or public cloud setting.

Abstract: The data storage system according to certain aspects can implement table level database restore. Table level database restore may refer to restoring a database table and its related data without restoring the entire database. The data storage system may use table metadata index to implement table level restore. A table metadata index may be created for each table, e.g., during a backup of the database. The table metadata index for a table can include any type of information for restoring the table and its related data. Some examples of the type of information included in the table metadata index include the following: container for the table, table backup location, system data, table index, table relationships, etc. Table metadata index can make the restoring of tables fast and efficient by packaging information that can be used to restore a table and its related data in an easily accessible manner.

Abstract: This application discloses a system for presenting data to a user based on requests to move data from primary storage to secondary storage. The system receives a request to move data that satisfies at least one criterion, from primary to secondary data storage. The system then identifies an initial database query from the request, and further builds a nested database query from the initial database query according to a database schema. Next, the system estimates a size of a result of executing the nested database query. Finally, the system provides for display to the user the estimated size.
