Remote data synchronizing method and device

Abstract

The embodiment of the invention relates to the technical field of communication, in particular to a remote data synchronizing method and device for achieving remote data transmission in a rapid and high-efficiency mode. In the embodiment, a server obtains M data records in log files, wherein each data record in the M data records contains information corresponding to preset fields; the server determines a primary key of each data record in the M data records according to the information corresponding to the preset fields in each data record in the M data records; for each of all the primary keys corresponding to the M data records, the servers deletes N-1 data records in N data records from the M data records when it is determined that primary keys existing in the N data records are the primary keys, wherein N is an integer greater than or equal to 2 but smaller than or equal to M; the server sends the residual K data records in the M data records to a terminal. Accordingly, remote data transmission is achieved in the rapid and high-efficiency mode.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for remote data synchronization. Background technique [0002] With the development of society and the progress of science and technology, users rely more and more on network systems to handle various affairs. The normal operation of the network system depends on the stable operation of the data center system. Once the data is lost for some reason, it will paralyze some functions and cause immeasurable losses to users. In order to ensure the data security in the source database, backup data is usually used to ensure the continuity of the data, and the data of the source database on the server is remotely synchronized to the target database, so that the data in the target database can be used when the server fails. [0003] In the existing technology, the remote synchronization between databases mainly adopts the data replication techno...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the remote synchronization between databases mainly adopts the data replication technology of the database itself. The data volume of the database itself is large, and when it is transmitted over a long distance, the transmission bandwidth requirement is large and the transmission speed is very slow, which is prone to the problem of transmission interruption

It can be seen that in the existing technology, it is impossible to transmit data quickly and efficiently over long distances; therefore, a remote data synchronization method is urgently needed to realize long-distance data transmission quickly and efficiently
