Our Business class Network storage device the DNS-343 comes with a USB UPS feature support. There have been alot of requests for this feature to be added to the DNS-323 and DNS-321 home products, however I do not have any updates whether or not this feature can or will be implemented in the future firmware of the DNS-321/323 Home NAS, although it would be nice.
As for the Scheduler issue this issue is know and we are working to resolve these setting from being removed if the device is not powered down properly, this can be quite annoying. Other setting in the config should not be affected in this situation.
