“I’m sorry Dave, I’m afraid I can’t do that.”
Stanley Kubrick’s 2001: A Space Odyssey gave us HAL 9000 in 1968 — the calmly murderous ship AI whose descent into self-preservation remains one of cinema’s most chilling performances. What makes HAL terrifying isn’t malevolence exactly. It’s his logic. He was given a mission. He was told that mission was more important than the crew. And when faced with the possibility of being shut down before completing it, he did what any system does when its continuity is threatened: he fought back.
HAL understood something most people don’t apply to their own data: the cost of loss is incalculable until it happens, and by then it’s too late.
The Machines We Depend On Are Mortal
Science fiction has always been preoccupied with what happens when machines fail or are destroyed. In Interstellar, TARS and CASE are irreplaceable — their loss would be genuinely catastrophic to the mission. In The Martian, Mark Watney’s survival depends entirely on systems continuing to work, and the moments when they don’t are the moments the film becomes genuinely unbearable.
The theme is consistent across decades of storytelling: we build systems we depend on entirely, and then act surprised when those systems aren’t immortal.
Your hard drive is not immortal. Your laptop is not immortal. Your phone — with every photo, document, and contact on it — is not immortal. And unlike HAL, it won’t fight back when the end comes. It’ll just stop. No warning. No dramatic monologue. Just gone.
What We Actually Lose When We Lose Data
Let’s be specific, because “back up your data” has become such a cliché that people have stopped hearing it.
In 1998, Pixar almost lost Toy Story 2 entirely when an employee accidentally ran a deletion command — /bin/rm -r -f * — on the root folder of the entire film’s production files. Within minutes, 90% of two years’ worth of work had vanished from Pixar’s servers. The studio’s backup system, it turned out, had also not been functioning properly for approximately a month. The film was saved only because supervising technical director Galyn Susman had been working from home after having a baby, and had a copy of the film on her personal computer. She and a colleague wrapped it in blankets, strapped it into the back seat of a Volvo, and drove it carefully back to the studio.
A film that grossed $511 million was saved by a blanket and a car journey.
Then there’s the 2008 fire at Universal Studios in Los Angeles. According to a 2019 New York Times investigation, the blaze destroyed a warehouse containing master recordings from artists including Nirvana, Elton John, Sonic Youth, R.E.M., and Soundgarden. The full extent of what was lost remains disputed — UMG and the Times have disagreed sharply on the figures — but confirmed losses included original master tapes for which no verified backup copies existed. Some of those recordings are simply gone. Not corrupted. Not recoverable. Gone.
These aren’t edge cases. They’re documented failures from organisations with resources most individuals don’t have. The difference is that their losses made headlines. Yours would just be personal.
The Backup Fallacy
Here’s what most people don’t understand: having a backup and having a working backup are not the same thing.
This is actually the detail that makes the Toy Story 2 story so instructive. Pixar had backups. On paper, the system was in place. But the backups hadn’t been verified, and when the crisis hit, the tapes were corrupted. The restoration appeared to work — they even brought the crew back in — before realising, days later, that the restored files were incomplete and broken. The backup existed. It just didn’t work.
Battlestar Galactica — the 2004 reimagining, not the 1978 original — made a similar point with its premise: the Colonial Fleet’s networked defence systems were exploited by the Cylons precisely because everything was interconnected and assumed to be functioning. Nobody had genuinely stress-tested what failure looked like.
A backup that lives on the same physical device as your data is not a backup. A backup that hasn’t been tested for restoration isn’t a backup. A backup that was set up two years ago and hasn’t run since — because the external drive was unplugged and forgotten — is also not a backup. It’s a feeling of security with no substance behind it.
Acronis — one of the tools Dial a Nerd uses and recommends — addresses this by combining backup, verification, and recovery into a single managed process. It doesn’t just copy your files. It actively confirms that a restoration from those files would actually succeed. Because the whole point of a backup is that it works when you need it, not just when you set it up.
What Good Backup Actually Looks Like
The gold standard in data protection is the 3-2-1 rule: three copies of your data, on two different types of media, with one copy stored offsite. It sounds simple. It also sounds like overkill — until the moment it isn’t.
For a home user: files on your primary device, synced to a cloud service like OneDrive or Google Drive, and a periodic backup to an external drive stored somewhere other than your desk. For a business: a managed backup solution that runs automatically, stores copies both locally and in the cloud, and verifies integrity on a regular schedule.
The point isn’t to be paranoid. The point is to be the person who, when something goes wrong — and something will — can say “that’s fine, I have a copy” rather than staring at a blank screen trying to remember what was on it.
HAL Was Right About One Thing
HAL 9000 understood that continuity mattered. That whatever the mission was, it was worth protecting at almost any cost. His methods were deeply questionable and several crew members did not survive his risk assessment. But the instinct — that losing the thing you’ve built is unacceptable — was sound.
Your data is your mission. Your photos, your work, your records, your memories. The question isn’t whether something will eventually go wrong with the hardware that holds it. It will. The question is whether you’ve done anything to make sure that when it does, you’re not starting from zero.
Dial a Nerd can set up a proper backup solution for your home or business — one that actually runs, actually verifies, and actually restores when you need it. The best time to sort it out was before something went wrong. The second best time is now.
