Data hot backup method and system

Abstract

The invention discloses a data hot backup method and system. The data hot backup method comprises the following steps: creating a simulation node and configuring the attribute of the simulation node to ensure that the simulation node does not provide data access service; when the data of any working node in a database cluster needs to be backed up, copying by utilizing the simulation node so as to obtain the data of the working node; and backing up the obtained data into a memory machine by utilizing the simulation node. According to the data hot backup method and system, the data hot backup is realized, the condition of increasing the working pressure of the other working nodes when the data of any working node in the database cluster needs to be backed up is avoided, and the data backup method is optimized.

Description

technical field

[0001] The invention relates to the technical field of computer networks, in particular to a data hot backup method and system. Background technique

[0002] MongoDB is a database based on distributed file storage, written in C++ language, designed to provide scalable high-performance data storage solutions for WEB applications. MongoDB is a product between a relational database and a non-relational database. It supports a very loose data structure and is in the bjson format similar to json, so it can store more complex data types. The biggest feature of MongoDB is that the query language it supports is very powerful. Its syntax is somewhat similar to object-oriented query language. It can almost realize most of the functions similar to single-table query of relational database, and it also supports indexing of data. Compared with traditional relational databases, MongoDB has the characteristics of simple operation, completely free, open source code, downloa...
