The 3-2-1 Backup: Your Digital Life Insurance

Imagine losing all your children's photos, your tax documents, or the novel you've been writing for two years. It's the catastrophic scenario that too many people experience every year.

The good news? There is a universal, simple, and infallible rule to protect yourself: the 3-2-1 strategy.

The Rule in Detail

• 3 copies of your data: The original + 2 backups. If one copy is corrupted, you have others.
• 2 different media: Don't put everything on the same type of drive. For example, use your computer's hard drive AND an external USB drive.
• 1 copy off-site: This is the most important one. In case of fire or burglary, your drives at home disappear together. The off-site copy (Cloud or drive at a friend's house) is your ultimate safety net.

How to Apply It Simply?

No need to be an IT expert. Here is a typical configuration for an individual:

1. Daily work: Your files are on your computer.
2. Local backup (Automatic): An external hard drive permanently connected that copies your files (via Time Machine on Mac or File History on Windows).
3. Off-site backup (Automatic): A secure Cloud service (like Backblaze, Carbonite, or even OneDrive/Google Drive for essential files) that sends your data online in the background.

Set this system up once, and forget about it. Your peace of mind is priceless.
