real-time

All,

I'm working on a Real-time system, VxWorks I think, I'm saving application settings to a file. What's the best way to handle preserving the settings if the system shuts down or loses power in the middle of a file write? All I can think of is shuffling a few files around or reducing the frequency at which i Save variables in order to reduce incidents.
