I have an Exchange 2010 server, pre-sp1. I know in 2007 you could replicate the DB to local storage called Local continuous replication. I know that there is a new feature for DAG services, but what i want to do is host a copy of my mail db and have it replicate to an attached iSCSI drive that goes to our central storage server. I'm not terribly worried about the server completely crashing, rather the drives going nuts and having that store somewhere else. we are a mid size shop and I don't have another server that can be a fail-over mailbox server as described in the DAG instructions. I'm basically looking for something simple to replicate my db's in real time.
