Best practices on Coding

Question

On daily basis , I work on lot of data manipulation, cleaning etc., My question is when should we create a copy of data after analysis and when not. if I create separate data after each exercise that also doesn't make sense, I will get confused with so many data, but if I do manipulation in the same data, for some mistake I would have to run it again from beginning. are there any best practices we follow here?
