Problems solved by technology

However, this process takes a long time. During this process, the business system has been in an interrupted state. If the source business server has a large amount of data, the time for business interruption is unbearable, especially when the source business server’s hardware failure or operation When the system fails, the time of business interruption is even more unpredictable

Embodiment

[0072] Such as image 3 and Figure 4 As shown, in this embodiment, the backup proxy service program is installed on the source business server, and the standby machine service program is installed on the target business service. A process of quickly restoring the business system multiple times based on the system backup point is as follows:

[0073] first. The backup agent service program obtains a consistent snapshot point through the system online snapshot technology, and then backs up the snapshot point to the data storage server through the backup service program. The first backup can generate a full backup point, and subsequent backups can generate incremental backup points.

[0074] Secondly. Start the validation task of the backup point: Create a virtual switch for the validation task through software-defined networking technology, which is logically separated from the production network, so as to ensure that the network on which the validation task runs is the same...

Abstract

The invention discloses a method and system for quickly recovering a service system for multiple times based on a system backup point, and the method comprises the following steps: S1, carrying out hot backup of the production data of a source service server, generating a consistent snapshot point on a data storage server, and quickly building and pulling a temporary virtual machine based on the consistent snapshot point, to verify the backup data; S2, when the source service server fails, selecting a snapshot backup point with successful recent validity verification on the data storage server, quickly creating and pulling up a virtual machine on the data storage server based on the snapshot point, taking over the source service of the source service server, and writing data generated after pulling up the virtual machine into the data storage server; and S3, after the fault of the source service server is solved, recovering the data of the consistent snapshot backup point when the datastorage server takes over to the source service server, and synchronizing new data generated when the virtual machine takes over after the recovery is finished.

Description

technical field [0001] The invention relates to the technical field of computer disaster recovery and backup, in particular to a method and system for rapidly recovering a system multiple times based on a system backup point. Background technique [0002] With the continuous advancement of informatization construction, enterprises and institutions rely more and more on business systems. However, once the business system fails, the business interruption will bring more and more losses to enterprises and institutions. Therefore, when the business system fails, it is very important that the business system can work again within a few seconds and start the recovery of the business system immediately. [0003] In the business system, when the source business server fails, the business is interrupted, and the business needs to be repaired. In the prior art, the business recovery needs to go through the following process: repair the fault of the source business server, restore bus...
