Problems solved by technology

That is to say, in the virtual machine fault-tolerant system, all output information in response to the user's request must be released and sent to the user after the three-stage backup process is completed. The corresponding response information will generate additional delay time in the virtual machine fault-tolerant system
Accordingly, when facing delay-sensitive workload requirements (for example, online games, real-time transactions), the system response time cannot be guaranteed, and even disconnection or transaction failures may occur

Embodiment Construction

[0048] In order to be able to control the delay time of the workload in the virtual machine architecture with a fault-tolerant mechanism, the present invention dynamically adjusts the backup startup time point, thereby controlling the delay time within a set delay range.

[0049] Figure 2A is a structural diagram of a backup system according to an exemplary embodiment, and Figure 2B is a block diagram of a backup system according to an exemplary embodiment. It is important to understand that Figure 2A and Figure 2B The examples are only for convenience of description, and are not intended to limit the present invention.

[0050] Please refer to Figure 2A and Figure 2B , the backup system 100 includes a first server 110 and a second server 120, the first server 110 includes a processing device 112, a cache memory 114, a communication device 116, and a first virtual machine 118, and the second server 120 includes a processing device 122, a storage device 124 , a comm...

Abstract

A server backup method and a backup system using the server backup method are provided. The server backup method includes continuously collecting a plurality of dirty pages during a running operation and determining a backup start time point according to a quantity of the collected dirty pages. The server backup method also includes suspending the running operation according to the backup start time point and executing a backup snapshot operation to generate a data backup snapshot corresponding to the dirty pages, and executing a backup transmission operation to transmit the data backup snapshot.

Description

technical field [0001] The invention relates to a server backup method for a virtual machine architecture with a fault-tolerant mechanism, and a backup system using the method. Background technique [0002] In recent years, with the rapid development of the Internet and the rise of cloud computing, many enterprises have higher and higher requirements for information services. Therefore, virtual machines (Virtual Machines, VMs) with high computing capabilities are widely used in various solutions. plan. For example, a large number of servers running virtual machines are combined through the Internet to form an integrated computer with high-speed computing and large storage capacity, which is widely used by various enterprises. [0003] In order to avoid heavy losses caused by downtime or data loss caused by server failure, virtual machine fault tolerance (Fault Tolerance, FT) mechanism can be used to switch to another server immediately and without interruption when the serv...
