Abstract: Rather than relying on pre-defined scheduling of secondary copy operations such as backup jobs, the illustrative opportunistic approach initiates secondary copy operations based on changing operational conditions in a storage management system. An adaptive backup readiness score is based on a number of backup-readiness operational factors. An illustrative enhanced data agent which is associated with the target database application (or other executable component) may monitor the operational factors and determine the backup readiness score based on weights assigned to the respective operational factors. The enhanced data agent may evaluate recent backup jobs to determine which of the operational factors that contributed to the backup readiness score may have been most relevant. Based on the most-relevant analysis, the enhanced data agent may adapt the weights assigned to the monitored operational factors, so that the backup readiness score may be more suitable and responsive to ongoing operational conditions in the system.

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: 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: A streamlined approach enables customers to retain management control over their data in a database-as-a-service (“DBaaS”) setting, by providing managed backup copies outside cloud service providers' sphere of control. An illustrative data storage management system provides control over performing backup operations to generate managed backup copies, storing managed backup copies, recovering managed backup copies in whole or in part, migrating managed backup copies, and migrating DBaaS instances. Management control also extends to choices of where to store the managed backup copies, whether on the same cloud computing platform as the source DBaaS, on a different cloud computing platform, and/or in a non-cloud data center.

Abstract: A data storage system, according to certain aspects, automatically determines the accuracy of replication data when performing data backup operations. For instance, the system performs data backup using replication data rather than source data to reduce the processing load on the source system. The backup data is then associated with the source data as if the backup had been performed on the source data. If the replication system fails, then backing up replication data results in backup data that does not accurately reflect the source data. The system automatically determines the accuracy of replication data during data backup.

Abstract: A system according to certain aspects improves the process of restoring database objects and converting those objects into another database file format. According to certain aspects, a database file is backed up in a block-level fashion. Instead of restoring the entire backup file, which can consume a large amount of time and computing resources, the information management system may restore a particular database object from a backup database file that is stored as multiple blocks or other granular units. Then, the information management system can extract the desired data from the restored block(s). By using block-level mapping and storage techniques described herein, the system can restore a database object in a backup database file without restoring the entire backup database file, thereby speeding up restore operations and reducing consumption of storage and processing resources. In addition, the information management system can convert the blocks, using a staging memory, to another database file format as desired.
