Virtuoso provides the following flavors of snapshot replication:

Non-incremental snapshot replicationNon-incremental snapshot replication is useful when the data is changed infrequently or when data is modified in large portions at a time.
Incremental snapshot replication Incremental snapshot replication is useful when the data is changed frequently and implements incremental updates using a snapshot log.
Bi-directional snapshot replication Bi-directional snapshot replication allows data to be modified on both publisher and subscribers. This is useful read-write access to the replicas is needed.
[Note] Note:

Snapshot replication can be used in heterogeneous environments to set up replication between non-Virtuoso databases.
