I'd like to move mine to a Pi, but I'm a little concerned about storage. Do you store the controller database on the internal SD card or do you have it on a more robust external/network storage device?
Store everything on the SD card but make sure to create a backup image, just in case.
I've been running one in AWS on a micro instance and I don't like running it. I'd have paid for this had I seen it when I was doing this.
