摘要： A log structured content addressable deduplicated data storage system may be used to store deduplicated data. Data to be stored is partitioned into data segments. Each unique data segment is associated with a label. The storage system maintains a transaction log. Mutating storage operations are initiated by storing transaction records in the transaction log. Additional transaction records are stored in the log when storage operations are completed. Upon restarting an embodiment of the data storage system, the transaction records from the transaction logs are replayed to recreate the state of the data storage system. The data storage system updates file system metadata with transaction information while a storage operation associated with the file is being processed. This transaction information serves as atomically updated transaction commit points, allowing fully internally consistent snapshots of deduplicated volumes to be taken at any time.
摘要翻译：可以使用日志结构化内容可寻址的重复数据删除数据存储系统来存储重复数据删除的数据。要存储的数据被分割成数据段。每个唯一数据段都与一个标签相关联。存储系统维护事务日志。通过将事务记录存储在事务日志中来启动变量存储操作。存储操作完成后，其他事务记录将存储在日志中。在重新启动数据存储系统的实施例时，重播来自事务日志的事务记录以重新创建数据存储系统的状态。数据存储系统在处理与文件相关联的存储操作的同时，用事务信息更新文件系统元数据。此事务信息用作原子更新的事务提交点，允许在任何时间完全内部一致地执行重复数据删除卷的快照。

摘要： A spanning storage interface facilitates the use of cloud storage services by storage clients. The spanning storage interface presents one or more data interfaces to storage clients at a network location, such as file, object, data backup, archival, and storage block based interfaces. The data interfaces allows storage clients to store and retrieve data using non-cloud based protocols. The spanning storage interface may perform data deduplication on data received from storage clients. The spanning storage interface may transfer the deduplicated version of the data to the cloud storage service. The spanning storage interface may include local storage for storing a copy or all or a portion of the data from storage clients. The local storage may be used as a local cache of frequently accessed data, which may be stored data in its deduplicated form.
摘要翻译：跨越存储接口便于存储客户端使用云存储服务。跨越存储接口向网络位置的存储客户端提供一个或多个数据接口，例如文件，对象，数据备份，归档和基于存储块的接口。数据接口允许存储客户端使用非基于云的协议来存储和检索数据。跨越存储接口可以对从存储客户端接收的数据执行重复数据删除。跨越存储接口可以将重复数据删除的数据版本传输到云存储服务。跨越存储接口可以包括用于存储副本的本地存储器或来自存储客户机的全部或一部分数据。本地存储器可以用作经常访问的数据的本地缓存，其可以以其重复数据删除的形式存储数据。

摘要： A data virtualization storage appliance performs data deduplication transformations on the data. The original or non-deduplicated file system is used as shell to hold directory/file hierarchy and metadata. The data of the file system is stored by a separate data storage in a transformed and deduplicated form and may be implemented as one or more hidden files. The shell file system preserves the hierarchy structure and potentially the file metadata of the original, non-deduplicated file system in its original format, allowing clients to access file metadata and hierarchy information easily. The data of a file may be removed from the shell file system and replaced with a data layout that specifies the arrangement of deduplicated data segments needed to reconstruct the file data. The data layout associated with a file may be stored in a separate data stream in the shell file system.
摘要翻译：数据虚拟化存储设备对数据进行重复数据删除转换。原始或非重复数据删除的文件系统用作shell来保存目录/文件层次结构和元数据。文件系统的数据由转换和重复数据删除形式的单独的数据存储存储，并且可以被实现为一个或多个隐藏文件。 shell文件系统保留原始格式的原始，非重复数据删除的文件系统的层次结构和潜在的文件元数据，从而允许客户端轻松访问文件元数据和层次结构信息。可以从shell文件系统中删除文件的数据，并替换为指定重建文件数据所需的重复数据删除数据段的排列的数据布局。与文件相关联的数据布局可以存储在shell文件系统中的单独的数据流中。

摘要： In a network including WAN accelerators and segment-oriented file servers, a method comprises responding to a client request to manipulate a file via a network file protocol by receiving a first request at a first WAN accelerator, wherein the request is a request to open a file located at a file server that is a segment-oriented file server, sending a local request for the file, corresponding to the first request, from the WAN accelerator to the file server, using a segment-aware network request protocol, returning at least a portion of the requested file in the form of a representation of a data map corresponding to the at least a portion of the requested file stored on the file server and using a data map for reconstruction of the requested file.
