  • Patent number: 11847026
    Abstract: A data storage system according to certain aspects can share a single snapshot for multiple applications and/or agents. For example, the data storage system can receive snapshot commands from multiple applications and/or agents, and can group them for a single snapshot (e.g., based on time of receipt of the snapshot commands). Data associated with the multiple applications and/or agents may reside on a single LUN or volume. The data storage system can take a single snapshot of the LUN or volume, and generate metadata regarding which portion of the snapshot is related to which application. The single snapshot can be stored in one or more secondary storage devices. The single snapshot may be partitioned into portions relating to different applications and stored separately.

  • Patent number: 11640338
    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.

  • Patent number: 11507470
    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.

  • Patent number: 11245759
    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.

  • Publication number: 20210209060
    Abstract: An information management system according to certain aspects may determine whether storage operations will execute properly prior to executing them in a cloud services environment. 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.

  • Patent number: 10891197
    Abstract: The illustrative systems and methods consolidate storage-array command channels into a media agent that executes outside the production environment. 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 the storage array, yet lacks command channels to the storage array. Likewise, a “forwarder” proxy media agent may operate without command channels to the storage array. No third-party libraries or storage-array-command devices are installed or needed on the host computing device. The forwarder media agent forwards any commands directed at the storage array to the snap-MA on the secondary storage computing device. The snap-MA 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.
