Abstract

A data image management system, DIMS, includes a local data image manager, LDIM (202), a remote data image manager, RDIM (204), and a remote persistent storage device, RPSD (206). When used in a system having a local persistent storage device (110), the system may store a data image of the local storage device (110) in the RPSD (206). In order to achieve this, the LDIM (202) intercepts read/write requests intended for the storage device (110), and responds to those requests as if the LDIM (202) is actually the local storage. Thus, the LDIM (202) manages to emulate the storage device (110) while actually using the storage areas in the remote device (206).
