摘要: Storage of data segments is disclosed. For each segment, a similar segment to the segment is identified, wherein the similar segment is already managed by a cluster node. In the event the similar segment is identified, a reference to the similar segment and a delta between the similar segment and the segment are caused to be stored instead of the segment.

摘要: Cluster storage is disclosed. A data stream or a data block is received. The data stream or the data block is broken into segments. For each segment, a cluster node is selected, and in the event that a similar segment to the segment is identified that is already managed by the selected cluster node, a reference to the similar segment and a delta between the similar segment and the segment is caused to be stored on the selected cluster node.

摘要: File system replication includes determining whether one of a plurality of files included in an original file system has been updated since a previous replication, the file having a plurality of data segments, and in the event that the file has been updated, locating among the plurality of data segments a previously stored data segment that is newly referenced by the file, and that does not require replication.
摘要翻译: 文件系统复制包括确定原始文件系统中包括的多个文件中的一个文件是否已经从先前的复制更新,该文件具有多个数据段,并且在文件已被更新的情况下,位于多个 的数据段分段由文件新引用的先前存储的数据段,并且不需要复制。

摘要: A method of managing duplicate segments from a segmented file storage system is disclosed. The method comprises indexing a segment according to a key for the segments wherein the index includes an identification of a first data location where the segment is stored and identifying a duplicate segment having the same key that is stored in a second location. The method further comprises determining that the duplicate segment is an undesired duplicate segment and eliminating the undesired duplicate segment.

摘要: A method for storing data is disclosed. The method comprises receiving a data stream comprising a plurality of data segments and preliminarily checking in a memory having a relatively low latency whether one of the plurality of data segments has been stored previously. The method further comprises in the event that the preliminary check does not conclusively determine whether the data segment has been stored previously, limiting checking in a memory having a relatively high latency to conclusively determine whether the data segment has been previously stored, and in the event that checking is limited or in the event that the check in the memory having relatively high latency conclusively determines the data segment has not been previously stored, storing the data segment.

摘要: Cluster storage is disclosed. A data stream or a data block is received. The data stream or the data block is broken into segments. For each segment, a cluster node is selected, and a portion of the segment smaller than the segment is identified that is a duplicate of a portion of a segment already managed by the cluster node.
