You're getting to the crux of the issue now. If you don't have log files to recover corrupted data anyways, or that is you never saved it in the first place -- you CANNOT recover it. If you risk irreparably corrupting old data and new data, what is the value of your software system in the first place? Why not use google forms and google spreadsheets, data entry analysts and a call center and be done with the whole thing anyways? My point is that the very root of what gives software value is something deeply industrial -- it is a machine that can do something over and over correctly, reliably and without regressions. If you take away that reliability to be depended upon by a business, you are no longer building an industrial strength solution -- you're building a toy.
