The NSF CISE guidelines (which apply to much of the funded CS research that folks on HN care about) currently require you to retain all data required to reproduce your experiment and make them available to any reasonable request:

My advisor is on appointment there right now, and they're working on guidelines that require you to provide full reproducibility of your program results (modulo system differences). At least for software, things are looking up. Of course, reproducibility is both infinitely easier (I can do it on any system!) and harder (what do you mean the kernel patchlevel or CPU/GPU sub-model-number matters?).
