Server Archival

I would like to see a system similar to the Data Request button in the settings, but where you could request a server download of messages. I'm not sure how difficult that would be or what the size of a file that would take, but I feel like it would be a good idea to have for when you want to keep a server for something fresh but don't want to lose the history you already have. Since Discord already hosts images in links that you can open in a browser (correct me if I'm wrong with how this works), to limit file sizes a photo or gif could be saved as the link rather than the image itself. Each channel would have its own text file with at least just the names, times, and messages. Similar to the condensed chat option in the Appearance tab.
