Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] see image 3 As shown, the embodiment of the present invention provides a method for realizing data recovery through LUN, including the following steps:

[0049] The backup server receives the file recovery request initiated by the user, and the file recovery request specifies the date of the file to be recovered and the disk where the file is located; a new volume is added on the cloud data center host, and a new LUN is added on the backup storage;

[0050] The backup server copies the backup data from the backup storage LUN to the new LUN;

[0051] Remotely mount the new LUN containing the backup data to the virtual machine;

[0052] Log in to the virtual machine for file recovery.

[0053] In the embodiment of the present invention, the LUN is directly mapped to the virtual machine, and the data recovery of the volume cor...

Abstract

The invention discloses a method for realizing backup data recovery through LUN remote mapping, and relates to the technical field of cloud computing. According to the method, the new LUN on the backup storage is directly and remotely mapped to the new volume created on the virtual machine through the network between the backup storage and the cloud data center host, a user logs in the productionvirtual machine, then the file on the backup storage can be browsed and checked, and the data recovery is achieved. Meanwhile, the backup data is directly mapped to the virtual machine storage of thecloud data center from the backup storage; the process of copying the backup data to the backup server and then to the cloud data center host is not needed any more, the link of copying the backup data is shortened, and a certain file of the new LUN for recovering backup storage does not need to copy the whole LUN. The invention also discloses a system for realizing the backup data recovery through LUN remote mapping.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for realizing backup data recovery through LUN remote mapping. Background technique [0002] When building a cloud data center, it is often necessary to back up the virtual machines in the data center. After the backup of a virtual machine is completed, when restoring data, the user often only needs to restore a certain file in the past, but the existing recovery technology is generally difficult to meet the file-level data recovery, the entire disk needs to be restored, and the The recovered disk is copied from the backup server to the cloud data center, mounted to the virtual machine, and after the files are taken out, the disk is unmounted and deleted. The operation of the whole process is cumbersome, and the copying time is longer when the disk is large. [0003] Under normal circumstances, traditional backup software can only restore a single virtual machi...
