This feature is functionally close to replication and differs in the fact that it is implemented as a synchronnous process. This means that both replicas are identical all of the time. This feature brings about certain technical limitations. Please contact support in case you are interested in this feature, as some things need to be specified and negotiated. -- GitLab
