EdgeRouter
The default config output for VyOS routers is a json config file that can be restored from backup via the CLI, WebUI or from a Recovery Console with a DB-9/Rollover cable if you're having an especially bad time.
Again, this is my default VyOS router config with production data replaced with $VARIABLES.
