Problems solved by technology

[0006] For the above solution, if MongoDB is closed, the business will be interrupted and the error will be reported, which will affect the stability of the business; and the method of providing additional hidden data nodes does not need to close the database, but each data node requires an additional independent Server implementation, the cost is high, and the independent server does not undertake any business when it does not need to be backed up, which greatly wastes resources
The prior art has not yet mentioned that there is a better solution

Abstract

The invention provides a data backup method and device. The method comprises the steps of receiving a backup instruction that the database needs data backup during service provision conducted by the database; calling a clone instruction which the database itself has and cloning the data of the database; backuping the data obtained through clone to a target database. Seamless connection of services can be achieved through the data backup method and device, the anti-disaster ability and the robustness of services are improved greatly, and the experience of users on the services is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data backup method and device. Background technique [0002] MongoDB is a commonly used distributed database, mainly used to provide services or support for business. The service or support provided for the business needs to be real-time in order to keep the business online. Therefore, MongoDB needs to keep the service / support provided and cannot be closed. Once MongoDB is closed, it will cause business interruption, affecting business and user experience. [0003] However, MongoDB needs to back up data during use. The existing backup methods are as follows: [0004] 1. Close MongoDB, interrupt the running business, copy all data, and restart MongoDB locally after the data copy is completed; [0005] 2. Provide additional hidden data nodes for MongoDB, and import data into hidden data nodes. [0006] For the above solution, if MongoDB is closed, the business will be interrupted and...
