Problems solved by technology

[0004] However, this method not only requires a large cost investment, but also the synchronization of data in different data centers in the multi-data center method is mostly asynchronous (because the synchronization scheme is difficult to achieve in this method), there are still data problems caused by asynchrony. Cases of inconsistencies and missing latest data
At the same time, when one of the data centers is damaged and it is necessary to switch to another data center to provide services for front-end customers, it is still unavoidable that the lagging phenomenon that can be perceived by users is unavoidable.
Therefore, the excessive cost and poor actual effect make most small enterprises or customers who need data disaster recovery regret, and compared with the minor problems at the program operation level, the situation of physical damage is rare

Abstract

The invention discloses a data access method, and the method is based on the idea of main and standby redundancy, and also builds a standby database on the basis of a remaining storage space on storage equipment where main data is located besides a conventionally built main database. As the main database and the standby database are established in the storage space provided by the same storage device, synchronous storage of the to-be-stored data can be conveniently realized, and the problems of time difference caused by asynchronous data synchronization of the main database and the standby database arranged on different storage devices and latest data loss caused by the time difference are avoided; and moreover, delay-free switching of the query operation among different databases can be realized, so that a user cannot perceive the query operation. Meanwhile, extra data storage equipment does not need to be added, so that the cost is lower. The invention further discloses a data accessdevice, electronic equipment and a computer readable storage medium, which have the above beneficial effects.

Description

Technical field [0001] This application relates to the field of data disaster recovery technology, and in particular to a data access method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the continuous development of electronic information, the amount of data has exploded, and various online services are inseparable from massive data as technical support, so data storage is very important. [0003] In order to ensure the complete and stable storage of data, there are many disaster recovery solutions. The common disaster recovery solutions are mostly aimed at the physical destruction of data storage devices. For example, adding a data storage center in the same city or in a different place can be used in different locations. The location adds data storage centers to prevent one of them from being damaged. [0004] However, this method is not only a large cost investment, but also the synchronization of data in different data c...
