Prevention of weight regain in formerly obese individuals requires 60-90 minutes of moderate-intensity activity or lesser amounts of vigorous-intensity activity.
If you have lost weight and want to keep it off, 30 minutes is likely not enough. You need 60-90 minutes of moderate activity (like brisk walking) daily. If you prefer intense exercise, you can do less time of it to get the same benefit.
