The project is run by the U.S. 501(c)3 Non-profit called Institute for Reproducible Research (http://reproducibilityinstitute.org) and this site has an overhead cost of ~$500/year. We plan to fund this project for at least the next 30 years. The community hosts the data and we also coordinate donations of hosting from our sponsors (listed on the home page).
We also run the project ShortScience.org! Check it out!
The main goal is to facilitate distribution. We work with research groups and provide "best effort" hosting with the resources from our sponsors. We expect the uploader has a backup of the data in all cases.
