Yeah, only 30 mins. And just pray that you wouldn't need backup, that you did not set up. Or that nobody breaks in through hole that you did not patch in php, web server and whatever else you had to install.<p>Self-hosted solutions requires maintenance even if you don't anticipate it. It's not "just PHP". It feels like a zero cost (you have got the spare capacity server after all), but only until you hit a problem.
