Although rather archaic, I back up my weather data to an external drive at approx 12:20am daily via a windows .bat file run by Task Scheduler.
A command I have used in that file to export the registry entries for WD so it can be backed up is…
regedit /e c:\wdisplay\databackup\wdisplayftp.reg HKEY_CURRENT_USER\wdisplayftp.ini
so this will invoke regedit and export (/e) WD’s registry entries contained in HKEY_CURRENT_USER\wdisplayftp.ini and save to wdisplayftp.reg in a databackup folder in my wdisplay directory.
