【Newsletter#257】Is 3-2-1 Backup Enough? Have You Heard of the Upgraded 3-2-1-1-0 Backup?

[Crystal.Y@AST]

Here at ASUSTOR, we take data security seriously. With ASUSTOR College tutorials and our Newsletters, we teach proper data protection strategies like the 3-2-1 Principle. With that in mind, the 3-2-1-1-0 Principle extends the familiar 3-2-1 Principle, adding offline backup and error verification, making data protection even more leak-proof in today's environment of ransomware and hacker attacks.

What is the 3-2-1-1-0 Principle?
data copies: including the original data and at least two backup copies.
different storage devices: such as a NAS, hard drives, external devices, or the cloud.
offsite backup: storing one copy of your data in a different physical location.
offline or immutable backup: storing one copy of your data on an offline or immutable storage device helps prevent data modification from attacks, ransomware, or hackers.
errors: regularly verify that backups can be successfully restored, ensuring that no errors or issues occur during the restoration process.
