Abstract: An information management system according to certain aspects may determine whether snapshot operations will work prior to executing them. The system may check various factors or parameters relating to a snapshot 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 for which a snapshot should be obtained, availability of secondary storage devices, license availability for snapshot software, 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 snapshot operations. The result of the determination can be provided in the form of a report summarizing any problems found with the snapshot storage policy. The report can include recommended courses of action or solutions for resolving any identified issues.
Abstract translation: 根据某些方面的信息管理系统可以确定快照操作在执行之前是否工作。 系统可以检查与快照存储策略相关的各种因素或参数，以验证存储策略是否在运行时工作，而不实际执行策略。 一些因素可能包括：应获取快照的主存储设备的可用性，辅助存储设备的可用性，快照软件的许可证可用性，用于连接到主存储设备和/或第二存储设备的用户凭据，可用存储容量，连接性 到存储设备等。系统还可以检查是否支持与快照操作有关的特定系统配置。 可以以总结形式的报告的形式提供确定结果，其中概述了快照存储策略中发现的任何问题。 该报告可以包括建议的行动方案或解决任何确定问题的解决方案。

Abstract: A method and system for utilizing snapshots to provide copies of a database or other application or large data structure to computing devices receives a request for access to a copy of a database, and performs a snapshot of a storage volume containing the requested database. The system then clones the snapshot and mounts the snapshot to a computing device, thus enabling the computing device to access a copy of the database. In some examples, the system automatically updates copies of a database on a scheduled basis (e.g., daily or weekly basis) to refresh a database regularly.

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.

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.

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 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 my 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. For example, as described in greater detail herein, the systems and methods may 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 translation: 管理快照的说明性方法简化了在存储管理系统中如何和何时生成快照，从而可以生成更少的快照，而不会减少数据保护的范围。 一种新颖的统一快照存储策略可以管理任意数量的子客户端的快照。 基于统一快照存储策略的统一快照作业使说明性存储管理系统能够自动发现相关组件，并在存储阵列中每个目标逻辑单元号（“LUN”）最多生成一个快照。 每个快照可以包括存储管理系统中的任何数量的子客户端和/或客户端的数据。 因此，一个统一快照作业可以产生包括与管理统一快照存储策略相关联的所有子客户端的数据的最小但足够数量的快照。 增强型存储管理器可以管理统一快照作业。 一个或多个增强的媒体代理和/或数据代理可以参与统一快照作业以及随后的快照编目。
