    Abstract: A distributed, deduplicated storage system according to certain embodiments is arranged in a parallel configuration including multiple deduplication nodes. Deduplicated data is distributed across the deduplication nodes. The deduplication nodes can be networked together and communicate with one another according using a light-weight, customized communication scheme (e.g., a scheme based on FTP or HTTP). In some cases, deduplication management information including deduplication signatures and/or other metadata is stored separately from the deduplicated data in deduplication management nodes, improving performance and scalability.

    Abstract translation: 根据某些实施例的分布式，重复数据消除的存储系统被布置成包括多个重复数据删除节点的并行配置。 重复数据删除节点上分发重复数据删除数据。 重复数据删除节点可以联网在一起，并使用轻量级的定制通信方案（例如，基于FTP或HTTP的方案）相互通信。 在某些情况下，包括重复数据消除签名和/或其他元数据的重复数据消除管理信息与重复数据删除管理节点中的重复数据删除数据分开存储，从而提高性能和可扩展性。

    Abstract: A system according to certain embodiments associates a signature value corresponding to a data block with one or more data blocks and a reference to the data block to form a signature/data word corresponding to the data block. The system further logically organizes the signature/data words into a plurality of files each comprising at least one signature/data word such that the signature values are embedded in the respective file. The system according to certain embodiments reads a previously stored signature value corresponding to a respective data block for sending from a backup storage system having at least one memory device to a secondary storage system. Based on an indication as to whether the data block is already stored on the secondary storage system, the system reads the data block from the at least one memory device for sending to the secondary storage system if the data block exists on the secondary storage system, wherein the signature value and not the data block is read from the at least one memory device if the data block exists on the secondary storage system.

    Abstract translation: 根据某些实施例的系统将对应于数据块的签名值与一个或多个数据块和对数据块的引用相关联，以形成对应于数据块的签名/数据字。 系统进一步逻辑地将签名/数据字组织成多个文件，每个文件包括至少一个签名/数据字，使得签名值被嵌入到相应的文件中。 根据某些实施例的系统读取对应于相应数据块的先前存储的签名值，用于从具有至少一个存储设备的备份存储系统发送到辅助存储系统。 基于关于数据块是否已经存储在辅助存储系统上的指示，如果数据块存在于辅助存储系统上，系统从至少一个存储器设备读取数据块以发送到辅助存储系统， 其中如果所述数据块存在于所述辅助存储系统上，则从所述至少一个存储器设备读取所述签名值而不是所述数据块。

    Abstract: Systems and methods for protecting data in a tiered storage system are provided. The storage system comprises a management server, a media management component connected to the management server, a plurality of storage media connected to the media management component, and a data source connected to the media management component. Source data is copied from a source to a buffer to produce intermediate data. The intermediate data is copied to both a first and second medium to produce a primary and auxiliary copy, respectively. An auxiliary copy may be made from another auxiliary copy. An auxiliary copy may also be made from a primary copy right before the primary copy is pruned.
