Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The main solution of the embodiment of the present invention is: when the virtual machine detects an I / O operation, obtain the I / O data corresponding to the I / O operation; send the I / O data to the CDP module for the CDP The module backs up the I / O data to a preset storage device; when the CDP module establishes a connection with the virtual machine, it receives the I / O data sent by the virtual machine; when receiving the I / O data, it sends the The detected I / O data is backed up to a preset storage device.

[0041] Since the prior art needs to install client software inside the virtual machine, and the virtual machine systems are various, the installation is relatively complicated, and there is a problem that the virtual machine service is interrupted due to software incompatibility.

[0042] The present invent...

Abstract

The invention discloses a backup method of virtual machine data. The backup method of the virtual machine data comprises the following steps of when the virtual machine detects I/O operation, obtaining I/O data corresponding to the I/O operation; sending the I/O data to a CDP module for the CDP module to back up the I/O data to a preset storage device. The invention also discloses a system, a terminal and a computer-readable storage medium. The virtual machine does not need to install the CDP module internally, which will neither interrupt the business of the virtual machine, nor affect the business performance of the client. The detected I/O data can be continuously sent to the CDP module for the CDP module to be backed up to the preset storage device.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a virtual machine data backup method, system, device and computer-readable storage medium. Background technique [0002] Data security incidents that have occurred since 2017: github (social programming and code hosting website) code mistakenly deleted, Hearthstone game was mistakenly deleted; the recent Wanacry ransomware has made everyone pay more and more attention to data security. Through CDP (continuous data The continuous data protection) function can achieve RPO (Recovery Point Object, recovery point objective) second level, which can guarantee the business security of customers. However, in actual customer scenarios, most of the traditional backup methods can only achieve hourly or 15-minute backups, which means that once a data storage failure occurs, more than 15 minutes of data will be lost. It is unacceptable for some key businesses, such as enterprise ERP, or...
