More Information
Summary:A directory system for performing replication of directory data, in which a directory server on the consumer side can reconstruct replica data using a backup kept at any point in time. Information 10c for specifying the entry changed for the last time by replication performed by replication service 10' is recorded into the replica data 9c managed by the directory server on the consumer side. Based on this information, the replication service 10' can know the entry on which next replication is to be performed. Thus, the replication service 10' can recognize the difference between the master data 9s managed by the directory server on the supplier side and the replica data 9c, and can perform replication on this difference when only the replica data 9c is reconstructed using the backup.
