I've read the FAQ, but it isn't clear to me why "How do I make an automatic server backup in Minecraft? [closed]" was closed off-topic. There is a decent amount of activity on the server-administration tag. "Game-specific hardware and utilities" are allowed according to the FAQ, doesn't this count? The question seems like a relevant and pressing concern for anyone running a minecraft server. If not, why not?
The general guideline for such game-related topics is usually that they are on-topic, as long as the game is an essential part of the question, i.e. you can't remove the game from the question without rendering it meaningless.
So a question about server administration that is in no way specific about Minecraft would be off-topic, but issues that are specific to games are on-topic. I don't know enough about Minecraft servers to say which is the case here, it seems to me that forcing a consistent state of the game data is something that would be different for every application, so there seems to be a game-specific aspect to this.
