A kind of method based on nfs volume carry backup virtual machine, it is characterized in that, medium on media server is made to nfs volume, and be mounted on virtual platform, then the disk of virtual machine and configuration file thereof are copied on the nfs volume on media server carry, the nfs volume of media server is uninstalled from virtual platform after waiting virtual machine disk and configuration file thereof copy to finish.So both can successfully virtual machine be backuped on media server, lifting virtual machine backup rate that again can be at double, when user need to recover, the virtual machine on nfs volume can also be mounted on virtual platform, by direct registration virtual machine, reach the effect of momentary recovery.
The method specifically comprises the following steps:
201) set up the virtual machine task based on the backup of nfs volume carry;
202) carry out the task of nfs volume carry backup virtual machine, first backup server obtains the current disk size of wanting backup virtual machine, and the virtual machine disk size information getting is sent to the nfs volume management module of media server;
203) nfs volume management module, according to the size information that gets virtual machine disk, creates a nfs volume that can hold whole virtual machine disk;
204) nfs volume management module is mounted to newly-built nfs volume on the virtual platform of wanting backup virtual machine place;
205) backup server is to the virtual machine creating snapshot that will back up;
206) backup server is by calling the interface that copies disk on virtual platform, informs that virtual machine stamper that virtual platform will back up (with respect to having beaten sub-disk newly-generated after snapshot) and configuration file thereof copy in nfs volume;
207) after virtual machine disk and configuration file copy finish, nfs volume is uninstalled from virtual platform;
208) this nfs volume is brought in nfs administration module and managed, so far backup tasks finishes.
Described nfs volume management module manages the medium on media server, and the medium size required according to backup tasks, and medium is divided into N nfs volume.
Described nfs volume management module manages the nfs volume creating on media server, comprise nfs volume dilatation, dwindle and delete.
Compared with prior art, the present invention has the following advantages:
1, owing to adopting the mode of nfs volume carry, direct copying virtual machine disk and configuration file thereof, and same piece of data has more at least been lacked the read and write operation of a secondary data with normal backup mode, can significantly improve the backup rate of virtual machine, shorten BACKUP TIME.
2, owing to improving the backup rate of virtual machine, shorten BACKUP TIME, can reduce the consumption of virtual machine backup to virtual platform resource.
