I try to regularly request an XML backup of this wiki from Fandom. This is a very large XML file that has all the formatting and textual information from every page on the wiki. You can download this as well from the Special:Statistics page! Alternatively, I upload these files to the Google Drive whenever I save them, so anybody can access older database backups of the site. So, just in case the entire Fandom site crashes or there's some kind of asteroid disaster that wipes out most of the world order, you can still find this wiki's pages for free on Google Drive in our Archive Library.
To access the file, you can try opening it in your web browser or in notepad or another basic word processor. You'll have to go through a lot of formatting code but all the text from each page should be there, as well as all of it's edits.
Just to be clear, there are two versions of the XML database backup. The first is a basic backup of all the pages on the wiki. The second is a backup of all the pages on the wiki and their edit history. This file will show every iteration of a page. It will be difficult to see the edits and what changed from version to version but this is the best that can be done for now. I will name these files current' and full' respectively in Google Drive.
Happy archiving!
