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.
摘要翻译：公开了一种用于存储数据的方法。该方法包括：接收包括多个数据段的数据流，并且预先检查具有相对较低等待时间的存储器，以便先前已经存储了多个数据段中的一个。该方法还包括在初步检查不能最终确定数据段是否已经被先前存储的情况下，限制在具有相对高的等待时间的存储器中的检查以最终确定数据段是否已经被预先存储，并且在事件中该检查是有限的，或者在具有较高延迟的存储器中的检查结果确定数据段尚未被预先存储的情况下，存储该数据段。
