"The DMP should describe physical and cyber resources and facilities that will be used for the effective preservation and storage of research data. These can include third party facilities and repositories."
Please note that these DMP excerpts are copyrighted by their respective authors.
Preferred:
“As previously mentioned, data and codes developed during this research will be stored on both the PIs’ groups' local servers and on the campus servers. The campus servers are automatically backed up every day. Data generated at the University of Michigan will be stored in a repository called Deep Blue Data, while data generated at the University __________ will be stored in a repository called ______ providing 100Gb (expandable).”
Mentioning both short-term and long-term storage is good practice, and these are reliable storage options with automatic back-ups.
Less Developed:
“All data will be available at request immediately after the scientific results are published and will be stored at least another five years on magnetic and optical storage devices (hard disks, CDs, DVDs). Optical storage devices will serve the purpose of the Disaster Recovery Plan.”
Optical storage media are not sufficiently reliable for long-term archival storage.
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.
