Summary:A method, system, and program product are provided for minimizing replication when a new server is replicated with. A replication application for a client computer having a replica of a database thereon is executed by a processor in a computer to receive for a replication service comprising a plurality of servers containing replicas of the database, an indication of each healthy server in the replication service and a determined period of time within which replication is assured to have been completed for each healthy server. The replication application updates a replication history after successful completion of each replication by adding an entry comprising an identification for the server replicated with and a timestamp for the time of replication and by adding an entry for each other healthy server in the replication service containing an identification for the respective server and an imputed timestamp adjusted for the determined period of time.
