I would like to keep a backup of all the questions asked + all answers provided for each question, answers provided + questions for the answer provided, questions favourited on Stack Exchange in the very, very, highly unlikely case that the servers at Stack Exchange fail. How do I go about doing it beside copying everything into a Word document/WordPress? Are there any software or techniques available that would allow me to do a quick backup?
Regarding the questions you asked and answers you wrote:
See What is the easiest way for me to download all my comments across all Stack Exchange sites? and What is the easiest way for me to download all my questions+answers across all stack overflow sites?:
-- Display all questions+answers of a given user DECLARE @UserId int = ##UserId## SELECT Posts.Body FROM Posts WHERE Posts.OwnerUserId = @UserId -- Display all comments of a given user DECLARE @UserId int = ##UserId## SELECT Comments.Text FROM Comments WHERE Comments.UserId = @UserId
The main issue is that it needs to be run for each Stack Exchange website you want to retrieve your comments from, which can be pretty tedious to do.
