Data preservation Edit
"In principle, data from experiments that can be accurately reproduced need not be stored indefinitely. In practice, however, it may not be possible to reproduce precisely all of the experimental conditions, particularly where some conditions and experimental variables may not be known and when the costs of reproducing the experiment are prohibitive. In these instances, long-term preservation of the data is warranted. Thus, considerations of cost and reproducibility are key in considering policies for preservation of experimental data."
