The most heartbreaking thing that crosses my bench isn't a broken computer. It's a dead drive holding the only copy of ten years of family photos. Sometimes the data can be recovered. Often it can't, or it costs far more than a backup would have.
The fix is a simple rule that IT departments have used for decades.
What 3-2-1 means
- 3 copies of every photo you care about: the original plus two backups.
- 2 different kinds of storage, such as your computer and an external drive, so one failure can't take out everything.
- 1 copy somewhere else, outside your house, so a fire, flood, or break-in doesn't wipe out every copy at once. For most families, that's a cloud service.
A setup that takes one evening
Copy one: where the photos already are
That's your phone, your computer, or both. Gather everything into one main photo library on your computer first, so you're backing up a single folder instead of hunting across devices.
Copy two: an external drive at home
Buy an external drive with at least twice the space your photos take up today. On Windows, File History can back up your Pictures folder to it automatically. On a Mac, Time Machine does the same job. Plug it in, turn the feature on, and let it run.
Copy three: the cloud
Google Photos, iCloud Photos, Microsoft OneDrive, and Amazon Photos all keep a copy off-site. Pick the one that matches the devices your family already uses, and make sure automatic upload is turned on for every phone in the house.
Syncing isn't always backing up
Cloud services that sync your photos are great, but syncing works both ways. Delete a photo on your phone and it may disappear from the cloud too, after a grace period. That's why the external drive matters: it gives you a copy that isn't tied to what happens on your phone.
What about the boxes of prints?
The photos most at risk in many homes aren't digital at all. They're prints in shoeboxes and closets, slowly fading, with one copy in existence. A flood or a move gone wrong, and they're gone.
Scanning them brings them under the same 3-2-1 plan. Once they're digital, they go into your photo library and get backed up with everything else, and you can share them with the whole family.
