Hi @Stephan Gertsobbe, there is no exact equivalent for exporting an entire Studio project in a single XML file. The command I mentioned is the closest approximation. The best workaround is to use a terminal to do the export. Since you mentioned using these exports for backup and that you have server-side source control in use, I would expect that your files being tracked in source control would constitute the backup. 

Source control support for projects files themselves is limited due to the way we edit them. The Atelier REST API used by VS Code has no support for Studio Projects since the concept didn't exist in Atelier. VS Code uses SQL to modify projects instead. This mechanism was chosen for its backwards compatibility since Studio Projects users tended to be on older server versions. Source control UserActions are fired for projects, but not all of the lifecycle hooks will because we are not using object access. 

VS Code has a GUI that will help you debug REST services: https://docs.intersystems.com/components/csp/docbook/DocBook.UI.Page.cls...
