Abstract: An apparatus for eliminating duplication of a replicated file generates a hash key of a requested data block; checks if there is a data block same as the requested data block among data blocks of a replicated image file derived from a golden image file, which is same as the requested data block, by using the hash key of the requested data block; and records information of chunk storing the data block same as the requested data block to a layout of the data block if the same data block exists.
Abstract translation: 一种用于消除复制文件的重复的装置产生所请求的数据块的散列密钥; 通过使用所请求的数据块的散列密钥,检查从与所请求的数据块相同的黄金图像文件导出的复制图像文件的数据块中是否存在与所请求的数据块相同的数据块; 并且如果存在相同的数据块,则将存储与所请求的数据块相同的数据块的块的信息记录到数据块的布局。
