between Veritas Volume Replicator and Veritas Storage Replicator. I have a 6 GB database that needs to be replicated to the another server over a WAN. What's the best way to do this?

Veritas Storage Replicator is a Windows-based asynchronous data replication solution. It can replicate entire server volumes, file systems or single files across a WAN via IP. It also supports many-to-one replication meaning that many remote Windows systems can replicate to one central Windows system where data can be backed up.

Veritas Volume Replicator is supported on both Unix and Windows and is a volume-based replication solution. It requires the Veritas Volume Manager to be installed. Depending on the distance, replication can be synchronous or asynchronous. With Volume Replicator, it is also possible to replicate across heterogeneous platforms (i.e.: Solaris to AIX).

synchronous replication Synchronous replication copies data over a SAN, LAN or WAN so multiple copies are available. The technique is used for applications with low recovery time objectives.

data replication Data replication copies data from one location to another using a SAN, LAN or local WAN. This allows organizations to have current data available in case a disaster occurs. There are two types of data replication: synchronous and asynchronous.

asynchronous replication Asynchronous replication is an approach to data backup in which data is written to primary storage and then replicated to a replication target.

array-based replication Array-based replication applies the functionality of data replication across one or more storage controllers, which eliminates the processing overhead from servers and makes it easier to copy large amounts of data.

geo-replication Geo-replication is a type of data storage replication in which the same data is stored on servers in multiple geographic locations.
