    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 translation: 根据某些方面的数据存储系统可以将由多个客户端计算设备生成的数据（例如，备份，快照，归档等）的次要副本过滤到单个，过滤的全局参考文件中。 参考副本可以是数据存储系统中的次要存储数据的过滤视图或表示。 参考副本可以包括数据结构，其包括对满足某些过滤标准的次要存储数据的子集的引用。 过滤标准可以由用户根据用户偏好来指定。 包括在参考副本中的数据可以以本地格式（例如，生成数据的应用的格式）存储，并且可以通过与数据相关联的应用来访问。

    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 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.
