Restore database

Aagh, I just screwed something up. I tried to rename my project folder in the finder.
Docker and Wappler don’t seem to like that of course.
So I create a new blanc folder and retrieved the latest master from git.
Only thing now is that the database only contains the 4 standard tables.
I did use the ‘save database and structure’ option.
What is now the workflow to bring back this saved backup?
