SymmetricDS is open source software for database and file synchronization with Multi-master replication, filtered synchronization, and transformation capabilities. [2] It is designed to scale for a large number of nodes, work across low-bandwidth connections, and withstand periods of network outage. [3]
FRS is still used for SYSVOL replication, but optionally, DFS replication may be used instead of FRS replication for SYSVOL shares, [4] and the FRS stopped. On up-level Windows Server 2008 domain controllers, SYSVOL replication is performed using DFS replication, by default [5] although NTFRS replication is also supported. On Windows Server ...
MySQL Cluster automatically creates “node groups” from the number of replicas and data nodes specified by the user. Updates are synchronously replicated between members of the node group to protect against data loss and support fast failover between nodes. Cluster replication differs from "MySQL Replication", which is instead asynchronous.
MySQL: MySQL Group Replication, a plugin for virtual synchronous multi-master with conflict handling and distributed recovery was released with 5.7.17. Cluster Projects: MySQL Cluster supports conflict detection and resolution between multiple masters since version 6.3 for true multi-master capability for the MySQL Server.
The replication itself should be transparent to an external user. In a failure scenario, a failover of replicas should be hidden as much as possible with respect to quality of service. [4] Computer scientists further describe replication as being either: Active replication, which is performed by processing the same request at every replica
Oracle NoSQL Database supports multiple zones to intelligently allocate replication of processes and data, in order to improve reliability during hardware, network and power-related failure modes. The two types of zones are: primary zones that contain nodes that can serve as masters or replicas and are typically connected by fast interconnects.
In computer science, state machine replication (SMR) or state machine approach is a general method for implementing a fault-tolerant service by replicating servers and coordinating client interactions with server replicas. The approach also provides a framework for understanding and designing replication management protocols.
Administrative shares have the following characteristics: Hidden: The "$" appended to the end of the share name means that it is a hidden share.Windows will not list such shares among those it defines in typical queries by remote clients to obtain the list of shares.
