    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: 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 translation: 利用快照向计算设备提供数据库或其他应用或大数据结构的副本的方法和系统接收访问数据库副本的请求，并执行包含所请求的数据库的存储卷的快照。 系统然后克隆快照并将快照安装到计算设备，从而使计算设备能够访问数据库的副本。 在一些示例中，系统以计划的方式自动更新数据库的副本（例如，每天或每周），以定期刷新数据库。

    Abstract: The automatic, tiered retention storage system according to certain aspects can automatically classify data items based on content, such as based on the inclusion of search terms in the data items, or based on metadata or other characteristics associated with the data. Based on the classification, the system can assign the data items to corresponding user-defined “buckets.” In some embodiments, each bucket is associated with a particular tier in the storage system having a specific retention period.

    Abstract: Described in detail herein is a method of copying data of one or more virtual machines being hosted by one or more non-virtual machines. The method includes receiving an indication that specifies how to perform a copy of data of one or more virtual machines hosted by one or more virtual machine hosts. The method may include determining whether the one or more virtual machines are managed by a virtual machine manager that manages or facilitates management of the virtual machines. If so, the virtual machine manager is dynamically queried to automatically determine the virtual machines that it manages or that it facilitates management of. If not, a virtual machine host is dynamically queried to automatically determine the virtual machines that it hosts. The data of each virtual machine is then copied according to the specifications of the received indication.

    Abstract: In certain embodiments, a tiered storage system is disclosed that provides for failover protection during data backup operations. The system can provide for an index, or catalog, for identifying and enabling restoration of backup data located on a storage device. The system further maintains a set of transaction logs generated by media agent modules that identify metadata with respect to individual data chunks of a backup file on the storage device. A copy of the catalog and transaction logs can be stored at a location accessible by each of the media agent modules. In this manner, in case of a failure of one media agent module during backup, the transaction logs and existing catalog can be used by a second media agent module to resume the backup operation without requiring a restart of the backup process.

    Abstract: A method and system described herein for classifying data of virtual machines in a heterogeneous computing comprising virtual machines and non-virtual machines. The system may access a secondary copy of data stored by a virtual machine, create metadata associated with that data, store the metadata in an index that comprises metadata associated with data stored on non-virtual machines, using a journal file, determine modified data objects within the data stored by the virtual machine, access or create metadata associated with modified data objects, and update the index accordingly.
