I've read a number of posts about backing up Trello boards. They often seem to involve more complexity (JSON, GitHub) than I want or am competent to get into.
Is it a reasonable course of action to copy a board, close but not delete it? I assume that nothing in a closed board gets included in searches or shown on the home page. If some corruption occurs then I can always re-open the closed board.
Are there any pitfalls to this method? If not, is there a way to automate it?
