# Amazon Neptune Management API Reference This chapter documents the Neptune API operations that you can use to manage and maintain your Neptune DB cluster. Neptune operates on clusters of database servers that are connected in a replication topology. Thus, managing Neptune often involves deploying changes to multiple servers and making sure that all Neptune replicas are keeping up with the primary server. Because Neptune transparently scales the underlying storage as your data grows, managing Neptune requires relatively little management of disk storage. Likewise, because Neptune automatically performs continuous backups, a Neptune cluster does not require extensive planning or downtime for performing backups. **Contents** + [Neptune DB Clusters
