Restoring complete site in Runway

Should restoring a backup within Runway (version 3.0.8) restore the assets or just the database?

I have a backup configured to backup both database and assets. It has been running sufficiently long that all the assets are now stored in the dropbox directory (in subdirectories of the directory with the database backup sets).

A restore of the most recent backup (to a clean install) appears to only restore the database (and to be fairly only appears to claim to restore the database). Should this be the case? And if so is there any semi-automated procedure to pull the assets back from the dropbox backup store?
