    Abstract: A system and method are disclosed for providing efficient data storage. A plurality of data segments is received in a data stream. The system preliminarily checks in a memory having a relatively low latency whether one of the plurality of data segments may have been stored previously in a data segment repository. The memory having the relatively low latency stores data segment information. In the event that the preliminary check determines that one of the plurality of data segments may have been stored in the data segment repository, a memory having a relatively higher latency is checked to determine whether the data segment has been stored previously in the data segment repository.

    Abstract: Seeding replication is disclosed. One or more but not all files stored on a deduplicated storage system are selected to be replicated. One or more segments referred to by the selected one or more but not all files are determined. A data structure is created that is used to indicate that at least the one or more segments are to be replicated. In the event that an indication based at least in part on the data structure indicates that a candidate segment stored on the deduplicating storage system is to be replicated, the candidate segment is replicated.

    Abstract translation: 公开了播种复制。 选择存储在重复数据删除的存储系统上的一个或多个但不是全部文件进行复制。 确定所选择的一个或多个但不是全部文件所引用的一个或多个段。 创建用于指示至少一个或多个段被复制的数据结构。 在至少部分基于数据结构的指示指示将复制存储在重复数据删除存储系统上的候选片段的情况下，复制候选片段。

    Abstract: A system, method and computer program product for determining one or more candidate segments for replication. One or more but not all files stored on a deduplicated storage system are selected to be replicated. One or more segments referred to by the selected one or more but not all files are determined. A data structure is created that is used to indicate that at least the one or more segments are to be replicated. In the event that an indication based at least in part on the data structure indicates that a candidate segment stored on the deduplicating storage system is to be replicated, the candidate segment is replicated.

    Abstract: A system for storing data comprises a performance storage system for storing one or more data items. A data item of the one or more data items comprises a data file or a data block. The system further comprises a segment storage system for storing a snapshot of a stored data item of the one or more data items in the performance storage system. The taking of the snapshot of the stored data item enables recall of the stored data item as stored at a time of the snapshot. At least one newly stored segment is stored as a reference to a previously stored segment.

    Abstract: A system for storing files comprises a processor and a memory. The processor is configured to break a file into one or more segments; store the one or more segments in a first storage unit; and add metadata to the first storage unit so that the file can be accessed independent of a second storage unit, wherein a single namespace enables access for files stored in the first storage unit and the second storage unit. The memory is coupled to the processor and configured to provide the processor with instructions
