Preserving one's data is an excellent practice as it encourages reproducibility of research; this is one reason why many peer-reviewed journals and grant funding agencies require data be archived in a publicly-available repository.
Walker Library does not have a data repository; our institutional repository, JEWL Scholar, is for peer-reviewed materials, grey literature, and dissertations/theses -- not data sets.
Instead, we recommend you archive your data in a publicly-available repository. For each of these repositories, you can deposit your curated data and receive a citable DOI:
Inter-university Consortium for Political and Social Research (ICPSR)
