Problems solved by technology

[0003] Since each subsystem or database may be deployed on multiple different hosts, the traditional backup scheme backs up each host separately at the same time. Since the time of each host cannot be guaranteed to be absolutely uniform, coupled with factors such as

Example Embodiment

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The invention provides a backup recovery method of an application system. refer to figure 1 As shown in FIG. 2 , it is a schematic flowchart of a method for backup and restoration of an application system provided by an embodiment of the present invention. The method may be performed by a device, and the device may be implemented by software and / or hardware.

[0046] In this embodiment, the backup recovery method of the application system includes:

[0047] S1. Setting a distributed storage system as a backend storage system of a preset application system.

[0048] The distributed storage system mentioned in this case is a data storage technology that uses the storage resources in the disk space of each computer of an enterprise or individual connected to the network through the network, and forms these scat...

Abstract

The invention relates to a big data technology, and discloses a backup recovery method of an application system. The method comprises the following steps of dividing a distributed storage system of anapplication system into a plurality of block devices, sharing the block devices with the subsystems of the application system or the application hosts where the databases are located, controlling theapplication hosts to map the block devices into local block devices, and deploying the subsystems and the databases of the application system on the distributed block devices corresponding to the application hosts; performing a consistent snapshot on the block device group at a management end of the distributed storage system to form a consistent snapshot group; and recovering the data of the consistent snapshot group to an application host of the application system by adopting a cloning or rollback method according to the condition whether the application system is crashed or not. The invention further provides a backup recovery device of the application system and a computer readable storage medium. According to the invention, the quick and accurate backup and the data recovery of the database are realized.

Description

technical field [0001] The present invention relates to the field of big data technology, in particular to a method, device and computer-readable storage medium for an overall backup and restoration of an application system. Background technique [0002] With the development of the Internet, the current application system is getting bigger and bigger and more complex. In order to achieve high availability and high response speed, many large-scale systems are divided into several or even tens of hundreds of subsystems or microservices. Each subsystem Each microservice has one or more databases of the same type or different types. There are more or less correlations between these subsystems. Whether it is for each associated subsystem or the database under a certain subsystem, in the process of backup and recovery, users hope that all related subsystems and databases can maintain data consistency. [0003] Since each subsystem or database may be deployed on multiple differen...
