Claim:
1. An information processing system comprising: a first server which stores a plurality of directories and files; a second server which is coupled to the first server; and wherein the first server is configured to: receive an access request from a computer to a first directory or a first file among the directories and the files stored in the first server; store data of the first directory or the first file in the first server; and replicate the directories or the files which are stored in the first server to the second server; wherein, when a failure occurs in the first server, the information processing system is configured to: reconfigure a predetermined part of a hierarchic structure of the directories or files by obtaining metadata or entity data from the second server; and start receiving an access request from the computer after reconfiguration of the predetermined part of the hierarchic structure of the directories or files, and wherein, when an access request to a second file, which has not been restored from the second server, is received from the computer designating a file path of the second file, the information processing system is configured to: request the second server for metadata of a directory or a file for processing the access request to the second file; obtain the metadata of the directory or the file for processing the access request to the second file from the second server; reconfigure a part of the hierarchic structure of directories based on the obtained metadata; and respond to the request for the second file using the obtained metadata.
