TLDR
In this paper, a method for backing up or restoring a virtual machine is provided, which is based on the first and second union file system directory of the virtual machine, and the first directory is readable and writable and stores modifications to the base operating system file, and new files generated during running of the VM.Abstract:
A method for backing up or restoring a virtual machine is provided. The backup method includes creating a virtual machine having a first and a second union file system directory. The first directory read only stores a virtual machine base operating system file. The second directory is readable and writable and stores modifications to the base operating system file, and new files generated during running of the virtual machine. The virtual machine preferentially reads and writes the second directory. When a request to back up the virtual machine is received, the data in the second directory is backed up. The restore method includes preparing a virtual machine for restoring data. When a request to restore the virtual machine is received, the backup data of the second directory is obtained and restored to the second directory of the prepared virtual machine.read more
