Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a flowchart of a system cloning method in an embodiment of the present invention. Such as figure 1 Said, the method includes the following steps.

[0027] Step 101 , creating a silent snapshot file for the parent system that needs to be cloned in the source server, and saving relevant data in the parent system that needs to be cloned at a specified time point in the silent snapshot file. The designated time point mentioned here refers to the time point indicated to clone the parent system.

[0028] In a specific embodiment of the present invention, before creating a silent snapshot file, it is necessary to configure the storage mode of the parent system to be cloned in the source server, and configure the mappi...

Abstract

The invention discloses a system cloning method and device. The method includes: creating a silent snapshot file for a master system in a source server, to be cloned, and storing certain-moment related data of the master system, to be cloned, into the silent snapshot file; creating a second snapshot file, storing related data, which changes in the master system to be cloned after the certain moment, into the second snapshot file; generating a corresponding slave system in a target server according to the created silent snapshot file and the created second snapshot file. Through the system cloning method and device, the problems that the existing method is low in cloning speed, the system of the source server interrupts external services during the cloning process and the cloning success rate is low are solved.

Description

technical field [0001] The invention relates to the technical field of computer system cloning, in particular to a system cloning method and device. Background technique [0002] With the rapid development of virtualization technology, virtualization technology has been implemented in IT environment. After the deployment of the core application system is completed, due to the continuous expansion of the system and data, even a single high-end physical machine cannot realize the normal operation of the application. When it is necessary to use a minicomputer or a device with a higher operating speed, the existing tools and software cannot pass Cloning is achieved. The current traditional method of virtual machine cloning is to use the existing static cloning function of the virtual machine, that is, to suspend / resume the virtual machine, by suspending the running virtual machine on a machine, and then copying the saved virtual machine files to on the target machine, and then...
