Abstract

An embodiment of the invention provides a server of a distributed storage system and a data synchronizing method between servers. The method includes: the first server receives a data updating request and searches the data fragment corresponding to the keyword information in the data updating request; the data fragment is updated according to the updating data in the data updating request; if the fact that the second server with other data fragments identical with the data fragment in name is offline is detected, the data updating operation is recorded into the first log of the first server, wherein the data fragments with the same name are disposed in the first server and the second server; a log synchronization request transmitted by the second server is responded to, and the first log is returned to the second server. The method has the advantages that the second server only needs to perform data synchronization according to the first log, data synchronization efficiency is increased greatly, the servers can provide data services for users as soon as possible, and user waiting time caused by server offline can be reduced.

Description

technical field

[0001] The present invention relates to the technical field of distributed storage servers, in particular, the present invention relates to a server of a distributed storage system and a method for synchronizing data between servers. Background technique

[0002] With the advent of the era of big data, service providers based on the Internet or communication networks need to store massive amounts of data to support their operations. At the same time, service providers can provide users with more convenient and Personalized service, so as to achieve the purpose of improving its service level.

[0003] At present, massive amounts of data are usually stored by distributed storage systems. For example, technicians distribute server clusters and store massive data in different servers according to certain rules; these servers can usually provide users with services such as data query and data update according to user requests. In order to improve data security a...
