When you did autorestore no and you see no restore than most likely the directory explicitly given in the backup plugin does point to a location where the backup does not exist. Then the 'restore' function is hidden. In the plugin you should give a location where the backup is stored.
The autorestore post a fresh flash scans for the latest backup made on all mounted media (hdd/usb).
I'm using the default location on the hdd, so this should not be a problem.
