Abstract
Disclosed herein are a server duplication system and method and a storage medium storing a server duplication computer program. The server duplication system includes a primary server including a hypervisor including a hypervisor-based fault tolerance module and a first file system virtual machine (FS VM), and a first standby server including a hypervisor including a hypervisor-based fault tolerance module that exchanges data with a fault tolerance module provided on the hypervisor of the primary server and duplicates the primary server. The first FS VM provides a first file system that is shared by a user virtual machine (USER VM), and a buffer cache that is used in conjunction with the first file system is provided on virtual memory. The first FS VM is duplicated into the standby server using the hypervisor-based fault tolerance module of the primary server and the hypervisor-based fault tolerance module of the standby server.
