Storing Data

Considerations for data storage

Storing research data using a constellation of different devices (such as CDs, DVDs, flash drives, personal computers, external hard drives) can lead to the fragmentation of data and ultimately data loss. Whenever possible, follow the 3-2-1 Rule for storing your data:

Keep 3 copies of any important file (1 primary, 2 backup copies)
Store files on at least 2 different media types (e.g., first copy on an internal hard drive and a second in a secure cloud account or an external hard drive)
Keep at least 1 copy offsite (i.e., not at your home or in the campus lab)

Preservation: how it's different from storage

Preserving research data goes beyond storing files in a secure location. Following best practices for the preservation of your data files allows for future reuse, by yourself or others. It also demonstrates a commitment to maintaining the scholarly record of your research, and can be an important consideration by funders of future projects.
