Abstract: A data storage environment can include one or more virtual clients instantiated on a host proxy computing device. The virtual clients may have only indirect access to a storage device, and may access the storage device via the proxy computing device. For example, the proxy computing device receives storage operation requests from one of the virtual clients, such as a request to create, mount or revert a snapshot of virtual client data. The proxy computing device generally acts as an intermediary between the virtual clients and the storage device to carry out the snapshots or other storage operations. The proxy computing device may further receive a notification upon completion of the storage operations, and transmits relevant data to the requesting virtual client regarding the storage operation.

Abstract: The systems and methods herein permit storage systems to correctly perform data recovery, such as direct access recovery, of Network Data Management Protocol (“NDMP”) backup data that was modified prior to being stored in secondary storage media, such as tape. The systems and methods permit NDMP backup data to be encrypted, compressed, deduplicated, and/or otherwise modified prior to storage. The systems and methods herein also permit a user to perform a precautionary snapshot of the current state of data (e.g., primary data) prior to reverting data to a previous state using point-in-time data.

Abstract: An information management system according to certain aspects may determine whether storage operations will work prior to executing them. The system may check various factors or parameters relating to a storage policy to verify whether the storage policy will work at runtime without actually executing the policy. Some examples of factors can include: availability of primary storage devices, availability of secondary storage devices, license availability for performing that operation, user credentials for connecting to primary and/or second storage devices, available storage capacity, connectivity to storage devices, etc. The system may also check whether a particular system configuration is supported in connection with storage operations. The result of the determination can be provided in the form of a report summarizing any problems found with the storage policy. The report can include recommended courses of action or solutions for resolving any identified issues.

Abstract: An illustrative approach to managing snapshots streamlines how and when snapshots are generated in a storage management system, such that fewer snapshots may be generated without diminishing the scope of data protection. A novel unified-snapshot storage policy may govern snapshots for any number of subclients. A unified-snapshot job based on the unified-snapshot storage policy enables the illustrative storage management system to automatically discover relevant components and generate at most one snapshot per target logical unit number (“LUN”) in a storage array. Each snapshot may comprise the data of any number of subclients and/or clients in the storage management system. Accordingly, one unified-snapshot job may yield a minimum but sufficient number of snapshots comprising data of all subclients associated with the governing unified-snapshot storage policy. An enhanced storage manager may manage the unified-snapshot jobs. One or more enhanced media agents and/or data agents may participate in the unified-snapshot jobs and in subsequent cataloguing of the snapshots.

Abstract: A “snapshot-control media agent” (“snap-MA”) is configured on a secondary storage computing device that operates apart from client computing devices. A “forwarder” media agent operates on each client computing device that uses a storage array, yet lacks command channels to the storage array. The forwarder media agent forwards commands directed at the storage array to the snap-MA, which receives and processes commands directed at the storage array that were forwarded by the forwarder media agents. Responses from the storage array are transmitted to the respective forwarder media agent. The snap-MA pools storage-array-command devices to avoid capacity limitations in regard to communications channels at the storage array. The snap-MA operating in conjunction with the forwarder media agents enable the illustrative system to consolidate the communication of storage-array commands away from client computing devices and/or proxy media agent hosts and into the secondary storage computing device that hosts the snap-MA.
