Abstract
(EN)
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.
(FR)
L’invention concerne un système de sauvegarde de disque virtuel, comprenant un serveur en nuage (01), un hôte de service (02) et un hôte de sauvegarde (03). Le serveur en nuage (01), lors de la détection du démarrage de l'hôte de service (02) et de l'hôte de sauvegarde (03), envoie une commande de sauvegarde de disque virtuel à l'hôte de service (02) et à l'hôte de sauvegarde (03) de telle sorte que l'hôte de service (02) démarre un programme de serveur synchrone (022) prédéfini et que l'hôte de sauvegarde (03) démarre un programme client synchrone (031) prédéfini ; l'hôte de service (02) intercepte une opération d'écriture de disque virtuel d'un disque virtuel local lors de la réception de la commande de sauvegarde de disque virtuel, et envoie l'opération d'écriture de disque virtuel interceptée à l'hôte de sauvegarde (03) au moyen du programme de serveur synchrone ; et l'hôte de sauvegarde (03), lors de la réception de l'opération d'écriture de disque virtuel au moyen du programme client synchrone (031), écrit l'opération d'écriture de disque virtuel reçue sur le disque virtuel de sauvegarde. Ainsi, une machine virtuelle dans l'hôte de service (02) peut être normalement utilisée même en cas de défaillance d’un disque physique de l'hôte de service (02).
(ZH)
一种虚拟磁盘备份系统,包括云服务器(01)、服务主机(02)和备份主机(03);云服务器(01)在检测到服务主机(02)和备份主机(03)启动时,发送虚拟磁盘备份指令至服务主机(02)和备份主机(03),以供服务主机(02)启动预设的同步服务器程序(022),以及备份主机(03)启动预设的同步客户端程序(031);服务主机(02)在接收到所述虚拟磁盘备份指令时,截取本地虚拟磁盘的虚拟磁盘写操作,并通过同步服务器程序将截取的虚拟磁盘写操作发送至备份主机(03);备份主机(03)通过同步客户端程序(031)接收到虚拟磁盘写操作时,将接收到的虚拟磁盘写操作写到备份虚拟磁盘中。这样即使服务主机(02)的物理磁盘出现故障,服务主机(02)中的虚拟机也可以正常使用。
