3-2-1 Backup Rule
The 3-2-1 Backup Rule is a best practice for protecting your data. It suggests keeping three copies of your data: the original and two backups. These backups should be stored on two different types of storage media—for example, an external drive and cloud storage—to reduce the risk of simultaneous failure. Lastly, one backup should be kept offsite, away from your primary location, to safeguard against physical disasters like fire or theft. Following this rule helps ensure your data remains safe and recoverable even if something goes wrong.
