Problems solved by technology

[0004] The desktop virtualization system is usually a distributed storage system, that is, the virtual machine hard disk is located on one server, the backup read-write server is another server, and the storage server is another server. In this case, these servers are connected through the network. The current server generally adopts a Gigabit network card, and the speed of reading and writing network files is about 100MB / s, while the external transmission rate of the server's local SCSI interface hard disk can reach 160MB / s. SCSI is Small Computer System Interface, a small computer system interface. If you use Solid-state hard disk, the transfer rate can easily reach 500MB / s; therefore, the virtual machine file backup is vulnerable to network speed restrictions

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] An embodiment of the present invention provides a concurrent backup method for virtual machine files, which is applied in a virtualized desktop server cluster to perform file backup for a virtual machine cluster. The method includes:

[0026] S1. The backup management server presets a backup policy. After the backup policy is preset, the backup management server starts a backup execution server and sends the backup policy to the backup execution server.

[0027] Specifically, the backup strategy includes backup range setting, backup content setting, backup target location setting and backup time setting.

[0028] The backup scope setting defines the virtual machines or groups of virtual machines that need to be backed up; the virtual machines are uniquely distinguished by the virtual machine numbers or user IDs, that is, adding the virtual machine numb...

Abstract

The invention discloses a concurrent backup method and a system of virtual machine files, belonging to the technical field of data backup. The method comprises: mounting a backup execution server andscanning a mirror image of a virtual machine to be backed up to obtain a list of files to be backed up; splitting the list of files to be backed up to obtain at least two sub-lists of backup files; sending the at least two backup file sub-lists by The backup execution server to a corresponding number of proxy backup read / write servers respectively. Each proxy backup read / write server copies the files in the mirror of the corresponding virtual machine to the backup storage server according to the received backup file sublist. The invention mainly solves the problem that the virtual machine files are easy to be limited by the network speed when being backed up, can back up the files to be backed up to the storage server in a concurrent manner, fully utilizes the network resources, and improves the backup speed.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a concurrent backup method and system for virtual machine files. Background technique [0002] Data is very important to every computer user. Losing data may cause huge losses. Data backup is an important way to protect user data. [0003] At present, when data is backed up, the server generally performs a full backup of the virtual machine files. Specifically, the backup read-write server compresses and copies the complete virtual machine files to the storage server. [0004] The desktop virtualization system is usually a distributed storage system, that is, the virtual machine hard disk is located on one server, the backup read-write server is another server, and the storage server is another server. In this case, these servers are connected through the network. The current server generally adopts a Gigabit network card, and the speed of reading and writing network files i...
