The 3-2-1 Backup Rule for Family Audio

One copy is no copy, three copies is the minimum

Hard drives fail. Cloud services shut down. Phones get lost, stolen, or dropped in a lake at the worst possible moment. None of this is a hypothetical, it's just a matter of time, and most families only learn the rule after they've already lost something they can't get back. That's the story behind almost every archivist's obsession with redundancy. Nobody adopts the three two one rule because they're paranoid. They adopt it because they've already been burned once, or they've heard enough stories from people who have.

The rule itself is simple, which is exactly why it works. Keep three total copies of anything irreplaceable. Store them across two different types of media, a hard drive and a cloud account, not two hard drives sitting side by side on the same desk, since that protects you from nothing. And keep at least one copy somewhere physically separate from the rest, a different building, a different city if you can manage it, so a house fire or a flood doesn't take out every copy in one afternoon.

It sounds like overkill until you consider what's actually at stake. A crashed laptop is an inconvenience. A crashed laptop holding the only recording of your grandmother's voice is a loss with no fix. Families who build this habit early aren't more anxious than everyone else, they've just done the math on what's replaceable and what isn't, and they've decided not to gamble with the second category.
