I noticed that after my computer had been on for over an hour there was no bandwidth usage, this was odd as I set the frequency to hourly and my backup has not finished seeding yet.
When I opened the GUI it said the next backup was in a little under 2hours, I tried toggling the frequency selection to something else than back but it still quoted the same time.
Today when I turned it on I checked again and it was the same, it says 3hours to the next backup when the frequency is set to hourly, screen shot below:
