    Abstract: A method and system for creating an index of content without interfering with the source of the content includes an offline content indexing system that creates an index of content from an offline copy of data. The system may associate additional properties or tags with data that are not part of traditional indexing of content, such as the time the content was last available or user attributes associated with the content. Users can search the created index to locate content that is no longer available or based on the associate attributes.

    Abstract translation: 用于在不干扰内容源的情况下创建内容索引的方法和系统包括离线内容索引系统，其从数据的脱机副本创建内容索引。 系统可以将附加属性或标签与不是内容的传统索引的一部分的数据相关联，例如内容最后可用的时间或与内容相关联的用户属性。 用户可以搜索创建的索引来查找不再可用的内容或基于关联属性的内容。

    Abstract: Systems and methods for replicating database data and generating read-only copies of the replicated data in a clean shutdown state. For example, systems can include a tracking module (e.g., a filter driver) that monitors transactions from a database application to a source storage device to generate log entries having at least one marker indicating a known good state of the application. The systems further include a computer coupled to a target storage device comprising a database and log files. The computer processes the transactions, based on the log entries, to replicate data to the target storage device; performs a first snapshot on data stored in the database and log files; replays into the database data stored in the log files; performs another snapshot on the database; and reverts the database back to a state in which the database existed at the time of the first snapshot.

    Abstract: A storage system according to certain embodiments includes a client-side signature repository that includes information representative of a set of data blocks stored in primary storage. During copy or backup operations, the system can use the client-side signature repository to identify data blocks located in primary storage that are new or that have changed. The system can also use the client-side signature repository to identify multiple locations within primary storage where different instances of the data blocks are located. Accordingly, during a copy or backup operation of one client computing device, the system can source a data block that is to be copied to secondary storage from another client computing device that includes a second instance of the data block.

    Abstract translation: 根据某些实施例的存储系统包括客户端签名库，其包括表示存储在主存储器中的一组数据块的信息。 在复制或备份操作期间，系统可以使用客户端签名库来识别位于主存储中的新的或已更改的数据块。 系统还可以使用客户端签名库来标识数据块的不同实例所在的主存储中的多个位置。 因此，在一个客户端计算设备的复制或备份操作期间，系统可以从包括数据块的第二实例的另一个客户端计算设备中获取要复制到辅助存储器的数据块。

    Abstract: A system and method for using a snapshot as a data source is described. In some cases, the system stores a snapshot and an associated data structure or index to storage media to create a secondary copy of a volume of data. In some cases, the associated index includes application specific data about a file system or other application that created the data to identify the location of the data. The associated index may include three entries, and may be used to facilitate the recovery of data via the snapshot.
