I'm developing a data comparison tool in C# which uses the AF SDK to pull points data and compare with an external database. This is working fine but my next task is to compare in the other direction and then commit updates to Pi.
I'm afraid I knoow nothing of how Pi stores its data. How can I take a backup. Also, I'd like to try the compare / update again a different set of Pi data. Is there some kind of training dataset available?
