Do you have a mini description of the server side setup (code/fs/db)?

Just rsync/git-pull the stuff over, so that if the primary dies, that you can switch over manually. Split-brain is the biggest issue in these kind of setups. The fun detail is that basement servers are typically the most stable (except for the connectivity possibly), and if something breaks one can actually walk to that "datacenter" easily, often much quicker to fix too if one needs spare parts etc. And with cheap-ish power, and free cooling / colder environment (we got first snow at 1200m) it is price-wise cheaper than a colo'd box. That said though, I use private colo'd servers (because of home connectivity not always being superb and could not get more than slow cable speeds and upload at home still is slow), if you need a secondary/third VM somewhere on a static IP (colo'd), don't hesitate to yell, more than happy to donate one for Subsurface (and I am sure others here can do the same; it is always funny the names you see on this list ;) ). Also, the expertise + time for doing a full active-active version if one wants to go in that direction, I have setup my share of those systems. But as you say,.... if it is 99.8% running, meh, is not life critical.
