I have a client who is in need of a backup peer server. The current server is running Windows 7 and a Oracle Database. Their current server has been offline for over a week, three times last year. The client in question can't have this happen continuously. Both machines would need to be running the oracle database. My question is what kind of options can I offer my client as a backup server. He has already turned down a fail-over Server 2012 setup. Is their any option that I can offer him that wont run into the tens of thousands of dollars?
