Abstract

The present invention relates to a data exchange method between the kernel state and the user state for virtual container system disaster recovery. The present invention uses FUSE to move all recovery work to the user state to complete. Firstly, a FUSE file system is implemented, and one of the files is mapped To the / DEV / LOOP device, and then use this LOOP device as the shadow device of the disk to be restored, and the virtual machine manager uses this LOOP device to start the virtual container. Therefore, the access to the original hard disk will be intercepted in the FUSE file system, and the FUSE file system will communicate with the server to achieve efficient data recovery on demand.

Description

technical field [0001] The invention relates to the fields of computer operating systems and network storage, in particular to a data exchange method between a kernel state and a user state for disaster recovery of a virtual container system. Background technique [0002] With the development of science and technology, in the Internet field, the vulnerability of data in the face of disasters has become increasingly prominent, and the loss of data often brings significant economic losses, so people's demand for data security is getting higher and higher. The technology adopted to resist disasters is called disaster recovery backup technology, and its appearance can effectively prevent huge losses caused by irreversible data loss caused by disasters like the "911" incident. [0003] The disaster recovery backup system includes two parts: the disaster recovery system and the disaster recovery computer. The disaster recovery system transmits the disaster recovery data to the dis...
