Confusing Veritas'products

I'm interested in knowing more about Veritas products. The problems is that I still don't understand yet what's the difference between Veritas' volume replicator and Veritas' storage replicator. I have a 6 GB database that needs to be replicated to the other server over WAN. What's the best way to do that?

Volume replicator is block-based replication that requires volume manager underneath it. Remember that Win2k has Veritas VM already built in. Storage replicator is file-based replication. Block-based is probably the better choice for databases as file-based replication would push a lot of big files all the time, where block-based will only push the changed bites.
