Abstract: Offline messaging between a repository storage operation cell and one or more mobile/remote storage operation cells is disclosed. The repository cell is managed by a repository storage manager that communicates to and from the remote cell via a specially-configured media agent. The illustrative intermediary media agent is configured to: queue messages directed to the remote cell, process them according to applicable parameters (e.g., time-to-live constraints, updates, cancellations, etc.), and transmit the processed messages to the remote cell when connectivity is available. The intermediary media agent also relays messages from the remote cell to the repository, including responses by the remote to the processed messages received from the repository via the intermediary media agent.

Abstract: Illustrative storage manager and media agent are enhanced to interoperate with deduplication appliances. Advantages are realized when making secondary and tertiary copies and also when restoring from a deduplication appliance. Tiered indexing minimizes how much data is retained and stored at media agents. Tiered indexing enables media agents to efficiently extract needed information from deduplication appliances to make tertiary copies and to restore backed up copies. Interoperability techniques include media agents generating separate data streams to the deduplication appliance. Each data stream carries a different kind of data, e.g., payload data, metadata content, or high-level index information. On initial backup, the media agent instructs the deduplication appliance to deduplicate the payload data stream but not the other data streams, thus intelligently applying resources to data most likely to benefit from deduplication. For tertiary copies (copies of pre-existing copies at the deduplication appliance), the media agent avoids handling payload data altogether.

Abstract: A lightweight always-on monitoring, collecting, diagnosing, and correcting utility operates in an enhanced storage manager that manages a data storage managements system. The always-on utility provides a comprehensive and pro-active approach, which is intended to reduce, if not altogether eliminate, the need for after-the-fact diagnostics. The always-on utility also enforces so-called best practices and other heuristics, which include pro-actively activating certain database settings that are not enabled by default; manipulating certain aspects of the database to improve performance; and reporting aspects that are outside best-practice parameters to the trouble report system so that system administrators and/or developers may intervene before a catastrophic failure occurs. In some cases, the best-practice parameters represent heuristics designed by the present inventors to improve the performance and general health of the management database.

Abstract: According to certain aspects, a method can include receiving, in response to an indication that a data storage database is being restored to a second time before a first time such that the data storage database comprises a plurality of first archive file identifiers associated at the second time, a first instruction from a data storage computer, where the first instruction instructs a media agent to stop scheduled secondary storage operations associated with a deduplication database, and where the deduplication database comprises a plurality of second archive file identifiers; determining at least one second archive file identifier in the plurality of second archive file identifiers that does not correlate with any first archive identifier in the plurality of first archive file identifiers; and, for each of the at least one second archive identifier, instructing the deduplication database to prune an entry associated with the respective second archive file identifier.
