Once data are ready to be archived and shared they will most likely need to be transferred to a repository or data center with a commitment to long-term curation. Consider both backup and archival strategies as part of your data management planning process.
Your first choice for long-term data preservation should be a disciplinary repository serving a relevant area of research. If no such repository exists, consider our institutional repository, Deep Blue Data. Perpetual archiving in a curated disciplinary or institutional repository is the preferred solution for long-term data preservation. If there are no applicable repositories, describe how you will keep the data accessible for its expected useful lifespan.
Two ways to approach finding a repository (please note that services mentioned are options for you to investigate further, not endorsements):
"Long-term large-scale digital archiving requires systems, organizational structures, policies and business models that are robust enough to withstand i) technological progress, ii) failures, iii) changing standards, iv) changes in institutional missions, and v) interruptions in management and funding."
"The DMP should describe physical and cyber resources and facilities that will be used for the effective preservation and storage of research data. In collaborative proposals or proposals involving sub-awards, the lead PI is responsible for assuring data storage and access."
"For most ocean data there are designated National Data Centers where data must be deposited."
