How It Works

The 3-2-1 backup rule says: keep 3 copies of your data, on 2 different media types, with 1 copy offsite. For photographers, this typically means the working drive, a local backup drive, and a cloud backup or offsite drive. Hard drives fail without warning, and the question is not if but when. Budget for backup drives as part of your equipment cost, just like lenses and cameras.
