Abstract
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,for specifying the entry changed for the last time by replication performed by replication service,′ is recorded into the replica data,managed by the directory server on the consumer side. Based on this information, the replication service,′ can know the entry on which next replication is to be performed. Thus, the replication service,′ can recognize the difference between the master data,managed by the directory server on the supplier side and the replica data,, and can perform replication on this difference when only the replica data,is reconstructed using the backup.
