Copy content of /var/root to a USB disk

Under certain circumstances, such as a failure on an attached USB disk at a critical moment, StoredSafe might copy the affected files to it’s failsafe mountpoint, which normally is “/var/root”. If such an event occurs, insert a new USB disk and select this option to copy the files to the USB disk.
