Does Veritas' Volume Manager or Volume Replicator do this? If not, do you know of a product that does?
The volume replication option will allow you to mirror the local volumes to another host in the environment, it is an add-on to the volume manager.
You could also look at some of the host-based virtualization engines from DataCore and FalconStor which provide this capability as well. Or, as a final option, you can migrate your storage to an environment that supports snapshots on the storage device itself, such as Network Appliance FAS storage systems.
