The 3-2-1 Rule Explained

The 3-2-1 rule is the gold standard for data protection. Keep three copies of your data (the original plus two backups), store those copies on two different types of media (like an external drive and the cloud), and keep at least one of those backups in an off-site location.

Automation is Key

Manual backups are frequently forgotten. Use automated tools like Time Machine on macOS or File History on Windows. For your off-site copy, look into reputable cloud backup services that run in the background. By automating the process, you remove the risk of human error, ensuring your most precious files are protected around the clock.
