Sunday morning. A coffee. A hard drive clicking… click… Then nothing.


3 years of memories. First steps. Birthdays. Holidays.


👉 All gone.


What really hurts? It's not the hard drive. It's the thought:


'I knew it could happen… but I did nothing.'


A simple rule can prevent this. It's called the 3-2-1 rule. It takes 15 seconds to understand. But it can save you years of regret.

🛡️ The 3-2-1 Rule

3copies of your data

A single copy is a gamble.

Computer + external drive + cloud

2different media types

Two identical simultaneous failures are rare.

Local (SSD/HDD) + remote cloud

1off-site copy

Protects against fire, theft and disaster.

Encrypted cloud or a drive at a third-party location

🎯 In Practice (freelancer / business owner)

  • 💻Copy 1 → your computer
  • 🖴Copy 2 → external hard drive
  • ☁️Copy 3 → cloud (Backblaze, pCloud, Google Drive…)

🖴1. External Hard Drive

👉 1 to 2 TB is enough to get started.

  • Budget: €50–80 for a 2 TB drive
  • Prefer a portable SSD
  • Leave it plugged in permanently

🛠️2. Backup Tool

👉 Choose based on your OS.

  • Time Machine (Mac) — built-in and free
  • Veeam Agent (Windows) — free
  • rsync (Linux) — scriptable

☁️3. Cloud Backup

👉 Essential for off-site storage.

  • Backblaze — $9/month unlimited
  • pCloud — lifetime access available
  • Google Drive / iCloud — integrated into OS

⚙️4. Automation

👉 Manual = guaranteed to forget.

  • Scheduled daily backup
  • Continuous synchronisation (cloud)
  • Notification on failure

🔁5. Restore Test

👉 Without testing, it's a bet, not a backup.

  • 1 random file every 3 months
  • Simulate a total loss once a year
  • Document the recovery procedure

✅ Checklist (Do It Today)

⏱️ Estimated total time: ~30 minutes — years of data secured

  • 1Buy or connect an external hard drive
  • 2Install a backup tool (Time Machine, Veeam…)
  • 3Activate an encrypted cloud storage space
  • 4Configure automatic backup
  • 5Run a first restore test

🧠 The Key Point

The best backup? One that works without you thinking about it.

If it's manual → you'll forget.

If it's automatic → you'll be protected.

💛 Share this with someone who has no backup. One day, they'll thank you.

If your computer stopped working tonight… what would you lose? Is it worth 30 minutes to prevent it?
