Q. How long should data be archived and made accessible?
That depends upon a number of factors: how long the data remains valid, how frequently new data is collected, how it is used, who all might want to make use of it, and what its historical value might be to future researchers. Each discipline or community of interest may set standards for how long research data should remain accessible. When depositing your data into a data repository, you can discuss with its administrators how long you'd like that data to remain accessible.
