Provided is an information processing device for providing an application over a network as a distributed cloud, wherein the information processing device comprises a CPU, storage, and a router, is set so that primary and secondary are defined in file units therein, and is equipped with a redundancy management table which manages the correspondence between the primary and secondary files and an update management table which manages file update information. When the information processing device is to be replaced with a new information processing device, the storage of the information processing device in use is copied in advance over the network to a new information processing device at a remote location. Thereafter, file update management for the information processing device in use is commenced while the new information processing device is off the network and being transported, so that when the new replacement information processing device arrives at the remote location, only the primary files among the files that have been updated are copied to the new information processing device while the secondary files for the new information processing device are generated autonomously. |
