PROBLEM TO BE SOLVED: To provide a server duplication system capable of increasing response speed when a virtual machine invokes a file input/output call upon duplicating a server in which one or more virtual machines have been generated on a hypervisor.;SOLUTION: A computer program performs: generating a first file system virtual machine 140 on a hypervisor 110 of a primary server 100; installing a predetermined file system in the first file system virtual machine; disposing a buffer cache, operating in conjunction with the file system, in virtual memory allocated to the first file system virtual machine; generating a user virtual machine on the hypervisor in response to a user request so that the user virtual machine uses the file system by outsourcing; and duplicating the buffer cache into a buffer cache of a second file system virtual machine 240 generated on a hypervisor 210 of a standby server 200.;COPYRIGHT: (C)2014,JPO&INPIT
