It will run once per day and backup two small directories totalling 50mB. No further features are needed.
What I would do is use the windows built in "Task Scheduler"
Open control Panel -> Administrative Tools -> Task Scheduler.
You can create any simple repeatable task to fire at any time you'd like, such as 4:00 am when you're otherwise not using the machine.
I've used this before for this very purpose, copy active work to some place every night just in case the next day is one of those "everything I touch turns to crap" days - which happens...
Hope that works for you
