    摘要： The present invention relates to an apparatus and method for managing a file in a distributed storage system. The apparatus and method for managing a file in a distributed storage system calculates a retention time of the file based on at least one of a current time, a file creation time, a file modification time and a recent file inquiry time; selects the file as an archive file if the retention time of the file is larger than a predetermined reference time; and relocates an original file and some or all of copy files of the file selected as an archive file from an active server to an archive server or from an active disk to an archive disk. If the number of inquiries on the file selected as an archive file counted in a counting period is larger than a predetermined threshold value or the file is modified or changed, the original file and some or all of the copy files of the file are restored from the archive sever to the active server or from the archive disk to the active disk

    摘要翻译： 本发明涉及一种用于在分布式存储系统中管理文件的装置和方法。 用于管理分布式存储系统中的文件的装置和方法基于当前时间，文件创建时间，文件修改时间和最近的文件查询时间中的至少一个来计算文件的保留时间; 如果文件的保留时间大于预定的参考时间，则将文件选择为档案文件; 并将原始文件以及从活动服务器选择为档案文件的文件的某些或所有复制文件重新定位到归档服务器，或从活动磁盘重新定位到归档磁盘。 如果在计数期间被选择为归档文件的文件的查询数量大于预定阈值或文件被修改或更改，则原始文件和文件的部分或全部复制文件从 归档服务器到活动服务器或从归档磁盘到活动磁盘
