Abstract
The information system of the present invention is composed of multiple sites including a local file server and clients, and a data center having a center file server. When a user starts moving to a different site after using a file in the local file server through a client of any one site, the local file server replicates files of a user having the shortest predicted arrival site to a different site to a center file server preferentially based on a location information of each user. Further, at each site, files of a user having a short predicted time of arrival to its own site are downloaded based on the location information of the user.
