AB  - Distributed system rely on replication techniques to tolerate data failure and site disconnection thus ensur-ing flexibility of the system so as to preserve its dependability. The idea of replication is robust however practical implementation of the replication techniques is often rigid that would bring down system's de-pendability and performance. This study intended to evaluate existing techniques and then develop a new technique which later will be compared with the existing with the goal of to achieve better fault tolerance, dependability and performance in distributed systems. The new technique is constructed based on circular neighbor relationship and quorum-based protocol. The consistency and integrity of the replicated data that involved write and read operations on the replicas is ensured using Replica maintenance protocol. This techniques focused on synchronous solution as for its quorum execution or commitment protocol showed higher reliability and convenience to avoid conflicts compared to asynchronous solution.
