摘要： PURPOSE: An apparatus and a method for managing a file in a distributed storage system are provided to enhance system performance and efficiency by enabling the automatic conversion between an active file and an archive file. CONSTITUTION: A maintenance time calculation unit(241) calculates generation time of a file from a present time or a first maintenance time deducting a correction time and the second maintenance time deducting a resent query time of the file from the present time. A file selector(242) selects a file as archived file, wherein the first maintenance time of the file is longer than standard time. A file manager(243) relocates an original file and some or entire copy of the file selected as the archived file from an active server to an archive server or from an active disk to an archive disk.
摘要翻译：目的：提供一种用于管理分布式存储系统中的文件的装置和方法，以通过启用活动文件和归档文件之间的自动转换来提高系统性能和效率。构成：维护时间计算单元（241）计算从当前时刻起的文件的生成时间或减去校正时间的第一维护时间，以及从当前时间起扣除文件的重新查询时间的第二维护时间。文件选择器（242）选择文件作为归档文件，其中文件的第一维护时间比标准时间长。文件管理器（243）将原始文件和被选择为归档文件的文件的一些或全部副本从活动服务器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。

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 according to the present invention involve: calculating a file retention time on the basis of the current time, file creation time, file modified time, and/or the most recent inquiry time; selecting the relevant file as an archived file if the file retention time is larger than a preset reference time; and relocating, from an active server to an archive server or from an active disk to an archive disk, a portion or the entirety of the original file and a copy of the file selected as an archived file. In addition, a portion or the entirety of the original file and a copy of the relevant file is restored from the archive server to the active server or from the archive disk to the active disk, if the total number of inquires on the file selected as an archive file calculated for a predetermined period is larger than a predetermined threshold value, or if the file is modified/updated.
摘要翻译：本发明涉及用于管理分布式存储系统中的文件的设备和方法。根据本发明的用于管理分布式存储系统中的文件的设备和方法包括：基于当前时间，文件创建时间，文件修改时间和/或最近的查询时间来计算文件保留时间; 如果文件保留时间大于预设参考时间，则选择相关文件作为存档文件; 以及从活动服务器到存档服务器或从活动磁盘到存档磁盘重定位原始文件的一部分或全部以及选择作为存档文件的文件的副本。另外，如果选择的文件的总查询数量为1，则原始文件的一部分或全部以及相关文件的副本从存档服务器恢复到活动服务器或从存档磁盘恢复到活动磁盘在预定时段计算的档案文件大于预定阈值，或者如果文件被修改/更新。
