I will store all data on at least one, and possibly up to 50, hard drives in my lab. The directory structure will be custom, not self-explanatory, and in no way documented or described. Students working with the data will be encouraged to make their own copies and modify them as they please, in order to ensure that no one can ever figure out what the actual real raw data is.
Backups will rarely, if ever, be done.
Projects are processes. Any research project requires a certain amount of planning at the outset, and a project involving research data is no different. Over the past decade, federal grant-funding agencies have begun to require the inclusion of Data Management Plans as part of grant proposals. But planning out one's data management is valuable even when it's not just for a grant application.
Data that is well managed is data that lasts. With increased focus on reproducibility and replicability in research, research data benefits from organization and management. Furthermore, well managed data is often a priori FAIR (findable, accessible, interoperable, and reusable) data. Even if sharing is not an explicit goal regarding a research project, data management benefits even sharing data with your future self. Whether a week, year, or decade removed from capturing the data, you will benefit from a good description and organization of how that data was captured.
Over the past decade, federal grant-funding agencies and other funders have begun requiring data management plans (DMPs) as part of the grant application process. Often, they can be built from the templates provided by the DMPTool. They even provide some sample DMPs. However, just because a tool exists to template a DMP does not mean that DMPs should be boilerplate documents that seem more like a nuisance than anything else. Instead, DMPs are often the best way for the researcher and their team to imagine the longevity of their project, especially with regard to reproducibility and FAIR principles.
Whether filing a DMP with a funding agency or merely planning a research project, consider answering the following questions:
