I'm glad you found my post useful! Most of my work is open source; do you need help with something specific?

No, wikis are not backed up because they are separate Git repositories. They have a .wiki suffix at the end of the url. It's a good idea to add though; to scan for the existence of a wiki associated with the repo and clone it as well. I'll add it to my TODO list ☺
