Abstract
A computer 10a stores boot information OA1 and application information AP1 stored on a local disk 16a, the information being respectively stored as an OS1 shared file group in a shared LU1 and as a AP1 shared file group in a shared LUn+1. For personal information (including personal information of boot information or AP information), computer 10a stores the information as a user personal file group in an personal LU1. Computer 10a transmits image outline information, LU information and file information for the sets of information stored in shared LU1, shared LUn+1 and personal LU1 to an disk-image management server 30, where the information is stored in the storage device 31 of the disk-image management server 30.
