Maybe your development server crashed? You should see log output in the console where you started the rails server. Anyway, I recommend using the command line for creating backups in your development environment. Execute script/discourse backup in your discourse directory.
./launcher enter app
discourse enable_restore
discourse restore
The last command will print the available backup files (letting you know you really got it in the right place), then you can copy paste the one you want.
Amazing, thank you both @gerhard@pfaffman Super easy when you know how, hey.
Last question and I’ll leave you alone: how do I disable emails on the destination forum? I don’t want to spam bomb 3000 people… I’ve deleted the SMTP details from app.yml yet somehow I’m still receiving system emails form the production discourse and want to be reeeeeeeally sure I’m not going to accidentally email everyone.
