Virtual machine data backup optimization method and system

Abstract

The invention discloses a virtual machine data backup optimization method and system. The method includes: step 1, installing VDBA plug-in on a virtualization server, configuring VDBA IP address of the virtualization server, and establishing a safety communication channel between the virtualization server and the VDBA plug-in; step 2, determining selection and backup dispatching and data retentionof a virtual machine to be backed up by the virtualization server,, and assigning and sending to the VDBA plug-in as a selection result; step 3, after the VDBA plug-in receives the selection result,and making virtual machine snapshot according to the selection result; step 4, mounting the virtual machine snapshot on the VDBA plug-in, and judging whether repeating data exist or not; step 5, if yes, clearing repeating data of the virtual machine snapshot to take as backup data; step 6, enabling the VDBA plug-in to transmit the backup data to a backup server. The repeating data are detected anddeleted through the VDBA plug-in, so that storage space is greatly saved, a backup process is accelerated, and backup efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to a method and system for optimizing virtual machine data backup. Background technique [0002] Virtualization refers to virtualizing a computer into multiple logical computers through virtualization technology. Run multiple logical computers on one computer at the same time, each logical computer can run a different operating system, and the application programs can run in independent spaces without affecting each other, thereby significantly improving the work efficiency of the computer. [0003] Virtualization uses software methods to redefine and divide IT resources, which can realize dynamic allocation, flexible scheduling, and cross-domain sharing of IT resources, improve the utilization rate of IT resources, and enable IT resources to truly become social infrastructure, serving flexible and diverse industries in all walks of life. changing application requirements. ...

Problems solved by technology

[0004] In the era of virtualization, the risk of data is not less than that in the physical environment. Since a server changes from a single server to multiple servers, data loss on the storage device will cause multiple services to be interrupted concurrently. Therefore, the importance of backup is definitely more important than traditional physical environments. The environment is much higher. Virtualization backup is mainly used to back up virtual machine files. The traditional virtualization backup function must be combined with third-party backup software. If it is to be used alone, it must be difficult to use commands. The virtual machine files need to be copied before they can be transferred to the backup server, which requires a large cache space. This kind of framework is unstable and needs to develop very limited scripts. It is only suitable for simple small and medium-sized enterprises
