Data Replication In Bi-directional, One-to-many,Many-to-one and Many-to-many Schemes

Real-time replication copies only the modified portion of a file. So no matter how many databases you have or how large the size of them, after the initial file sync, all real-time data replication should take only the minimal system resources and network bandwidth.

Four types of clustering structures for real time data replication can be set using ClusterReplica Enterprise 2.0.

1. Bi-directional data replication In this setting, the two "master" servers are both also function as a Replica Member to receiving data from the other. Typically, the two servers are a MS SQL server and an IIS web server. Creating a clustering for data protection and High Availability purposes without additional computers.
2. One-to-many data replication with Failover In this setting, the two Replica Member stations are used for local and remote data backup. The Primary master can be an IIS web server and a File server that needs to be alive 24x7. At the same time web programmers updates files on it daily.
3. Many-to-one data replication only This setting can involve a combination of A MS SQL server and an IIS web server A MS QL server and a File server A File server and an IIS web server Both servers need to backup data for data protection. The Data Version Management function allows File server end-users to self manage their working files.
4. Many-to-many data replication This is a more comprehensive setting. While the Primary Master manages the entire clustering structure, a Repli-Master server has its own sub-structure to replicate data to a local and a remote server for data protection. Typically in this setting, an IIS web server is installed as the Primary Master so that it can utilize Failover for High Availability. The Repli-Master is the MS SQL server that contains all kinds of databases and requires extra measure on data protection.
