Abstract: A communication system (50) can include a source node (31) coupled to a peer node (41), a source database (38) and a target database (48) at the peer node, and a logical unit (32 or 42). The logical unit can be programmed to forward data changes from source to peer node, monitor a health status of a replication task (34 or 44) by performing an audit on the source and nodes, and compare the audits on the source and peer nodes. The logical unit can be further programmed to perform at least one among the functions of synchronizing by launching a replication task synchronization thread (52) and a new target database (54) at the peer node and replacing the target database with the new target database upon completion of the synchronizing or switching over to the peer node upon detection of a critical failure at the source node during synchronization.
