Title: VIRTUAL DISK BACKUP SYSTEM, METHOD, APPARATUS, SERVICE HOST AND STORAGE MEDIUM
Abstract:
A virtual disk backup system, comprising a cloud server (01), a service host (02) and a backup host (03). The cloud server (01), when detecting that the service host (02) and the backup host (03) are started, sends a virtual disk backup command to the service host (02) and the backup host (03) so that the the service host (02) starts a preset synchronous server program (022) and the backup host (03) starts a preset synchronous client program (031); the service host (02) intercepts a virtual disk write operation of a local virtual disk when receiving the virtual disk backup command, and sends the intercepted virtual disk write operation to the backup host (03) by means of the synchronous server program; and the backup host (03), when receiving the virtual disk write operation by means of the synchronous client program (031), writes the received virtual disk write operation to the backup virtual disk. Thus, a virtual machine in the service host (02) may be normally used even if a physical disk of the service host (02) fails.
