Follow the 3-2-1 rule for backups

The 3-2-1 rule is a great general framework for backing up your data:

  • Have at least 3 total copies of your data backed up.
  • Ensure 2 of them are local but are on different media (e.g., external hard drives or SD cards).
  • Keep 1 offsite, likely in a cloud-based backup service.
