Abstract: The data storage system according to certain aspects can filter secondary copies of data (e.g., backups, snapshots, archives, etc.) generated by multiple client computing devices into a single, filtered, global reference copy. A reference copy may be a filtered view or representation of secondary storage data in a data storage system. A reference copy may include a data structure that includes references to a subset of secondary storage data that meets certain filtering criteria. The filtering criteria may be specified by users according to user preference. Data included in a reference copy may be stored in native format (e.g., format of the application that generated the data) and be accessible through the application associated with the data.

Abstract: An information management system uses cloud storage resources store secondary copies of primary data created by client computing devices managed by a storage manager. Deduplication operations are performed on the secondary copies, which results in chunk metadata indices that allow for tracking and faster retrieval of the deduplicated secondary copies. The chunk metadata indices may reference data segments of the deduplicated secondary copies. The data segments may be stored in, and across, one or more sub-files. As the secondary copies are aged out from the cloud storage resources, data segments are identified as being orphaned or non-orphaned. Data segments that are orphaned are pruned to remove their corresponding sub-files from the cloud storage resources, where the sub-files are replaced with new sub-files that do not contain the orphaned data segments.

Abstract: A disclosed framework enables virtually any aggressive Recovery Point Objective (RPO) to be enforced for a production database, without limitation on type of database management system (DBMS) or size of the production database. The framework overcomes technological barriers of the prior art, such as bottlenecks presented by a storage manager computer that traditionally managed database backups. To avoid the bottlenecks, an illustrative data storage management system does not engage the storage manager computer in storage operations that could impact the database RPO. Certain components are added and enhanced to autonomously capture database transaction logs, which are stored securely and persistently away from the DBMS. In a separate and less frequent operation, and with involvement of the storage manager computer, the illustrative system generates secondary copies in their final form. Meanwhile, temporary backup files can be used in restore operations without first being converted into secondary copies.

Abstract: An illustrative air-gapped data storage site for storing secure copies at the air-gapped storage site. Using specialized air-gapped media agents installed within the air-gapped storage pool site, the illustrative system, at an unpredictable time, establishes a one-way tunnel from secondary storage site to air-gapped site to receive backup copies of the data stored at primary site. In another embodiment, during disaster recovery, backup copies stored within the air-gapped site are replicated to a non-air gapped site (e.g., secondary storage pools) as “tertiary copies.” Those copies are then restored to the primary site in original application data formats for quick recovery. As restoration of data is complete, the tertiary copies are promoted to “secondary copies” to receive incremental backups.

Abstract: A data storage management system is enhanced to accommodate, and moreover to optimize, the storing and retention of deduplicated secondary copies at write-once read-many (WORM) enabled storage platforms. Enhancements include without limitation: user interface (UI) options to enable WORM functionality for secondary storage, whether used for deduplicated or non-deduplicated secondary copies; enhancements to secondary copy (e.g., deduplication copy, backup) operations; and pruning changes. The storage manager is generally responsible for managing the creation, tracking, and deletion of secondary copies, with and without deduplication. Media agents that store secondary copies to and prune them from the WORM-enabled storage platforms also are enhanced for communicating and interoperating with both bucket-level and object-level WORM-enabled storage platforms to implement the features disclosed herein.
