Every single hard drive you own will eventually fail. Not might fail — will fail. It is just a matter of time. The photographers who lose irreplaceable work aren't the ones who didn't care. They're…
The framework the data management industry has converged upon and that professional photographers, archivists, IT departments use is called the three, two, one rule.
It's simple enough to remember and comprehensive enough to protect against almost every realistic failure scenario.
If you have two copies and they're both in the same location, a single event, a flood, fire, power surge, can potentially take out both simultaneously.
Three copies, especially when distributed thoughtfully, means that two separate simultaneous failures would need to occur to lose your data permanently.
This protects against a class of failures that can affect multiple deviles- devices of the same type at once.
If all three copies are on the same brand of hard drive and that model has a firmware bug, which historically has actually happened, you could lose all three simultaneously.
Mixing media types, such as an internal SSD, an external hard drive, and a cloud service means no single technical failure can cascade across all of your copies.
This is the one most photographers skip, and it's the one that protects against the scenarios that feel unlikely that they will, until it has happened.
If all your drives are in the same building, they share the same physical risks.
In practice, for most photographers, a three-two-one system looks something like this.
Your working drive where you're doing your editing, a local backup drive or NAS system at home, and a cloud backup running continuously in the background.
It's achievable, it's not particularly expensive, and it's the baseline you should be building towards.
