3-2-1 Rule

The 3-2-1 rule is a reliable backup strategy to protect your data. It means you should have three copies of your data: the original and two backups. The backups should be stored on two different types of media (like an external hard drive and cloud storage) to prevent loss if one method fails. Finally, keep at least one backup off-site, away from your primary location, to safeguard against physical damage or theft. This approach ensures your data remains recoverable even in worst-case scenarios.
