I have a large collection of mp3 songs (approx 13.000) connected to an RT-AC96U via 128GB USB stick. The Asus is used in operation mode media-bridge and will be switched off over night. The problem is that the data base is erased on reset and "minidlna" starts scanning each time from the beginning, which lasts hours and therefore is unusable. Any hint to avoid this, e.g. manual synchronization only?
