Backups of digital data

As a researcher, you are responsible for ensuring that digital research data is backed-up regularly.

Backup refers to preserving additional copies of your data in a separate physical location from data files in storage. Backup preserves older copies so you can restore your data if accidental deletion/alteration or a disaster such as fire, flood, or hardware malfunction damages your data in storage.

If you store research data on personal hard drives, you should investigate the many free and commercial tools and services available for automatically backing up your system to an external hard drive. Online remote backup services are available, but you should be aware that the privacy and security policies of these services may not meet the legal and ethical standards expected of responsible researchers.

Back up Best Practices:

  • Make 3 copies (e.g. original + external/local + external/remote).
  • Have them geographically distributed (local vs. remote depends on recovery time needed).
  • Test your backup system ensure files can be recovered without corruption or data loss; do this both when you first set up your backup system, and then periodically throughout the course of your project.

Backup Options:

  • Hard drive (examples: via Vista backup, Mac Timeline, UNIX rsync)
  • Departmental or university servers
  • CDs or DVDs are not reliable backup mediums due to frequent failure.
