Hi all, I don't know much about commercial networking and VPNs, so be easy on me.

I work in a small office with a server (Windows Server 2012) and some workstations. For disaster purposes, we have recently purchased two identical servers and have one located onsite as our main server, and one offsite in a basement as an identical spare. Before we took the second server offsite, we loaded both servers with identical software and synced all the files and folders between both machines. Our goal is to link both servers via the internet and sync all the data from the onsite server to the offsite server. We would also like the ability to connect to the main server from our laptops while working remotely.

How is the best way to do this?

Our ISP will charge us $40+ per month to create a VPN tunnel to the 2nd location, but I am wondering if there is a better and cheaper way to get the job done. The 2nd location has an Asus RT-AC66U, which has some VPN capabilities, but I'm not sure it has the right kind of capabilities for the ISP's VPN. They don't offer support for 3rd party routers, and would only give me the settings I would need to input into the AC66U, but I don't see an option of where to input those settings. At our main location, the router that our ISP provides isn't very reliable, so we might need a new router for other reasons than just VPN capabilities.

I see articles about OpenVPN (and the price is right!) but I'd like some reassurances that that will do what we want...or, if there are other options that would work better. The fact that our ISP wants $40 per month for something that we can do for free makes me nervous that I'm not comparing apples to apples.
