<p>Given that metaoptimize disappeared overnight without any warning, and that - in my opinion - Stack Exchange doesn't care much about the perennity of user content, that's a fair question. We should all be worried about such an eventuality, and be prepared for it.</p>

<p>Stack Exchange provides <a href="https://meta.stackexchange.com/q/306316/178179">back-ups</a>, which are made infrequently, typically once every few months. These backups do not include images, which is a huge limitation. It would be nice if there were some initiative to create a dump of all images.</p>

<p>If you just care about your questions and answers, you can run this query:
<a href="https://meta.stackexchange.com/a/209317/178179">What is the easiest way for me to download all my questions+answers across all Stack Exchange sites?</a></p>

<p>It is very disappointing that Stack Exchange doesn't provide an easy way for users to export the entirety of their content. (but it's still better than Quora or Reddit, which don't even provide a dump)</p>

<p>FYI:</p>
