Quadrants/3-2-1-1-0
Storage Quadrants
The four Storage Quadrants are: Primary, Secondary, Nearline (Backups), Offline (Archives)
3-2-1 Rule - Good!
3 - Maintain at least THREE copies of your data.
2 - Store critical business data on at least TWO different types of media.
1 - Keep ONE copy of the backups in an off-site location.
3-2-1-1-0 Rule - Better!! ----- The "ZIP CODE of Availability"
In light of the growing trend of ransomware attacks and to keep ransomware from potentially attacking your backup data first, we’ve modified the Backup Best Practice from 3-2-1 to 3-2-1-1-0:
3 - Maintain at least THREE copies of your data.
2 - Store critical business data on at least TWO different types of media.
1 - Keep ONE copy of the backups in an off-site location.
1 - Add another ONE to the rule where one of the media is offline (immutable).
0 - Ensure all recoverability solutions have ZERO errors ("Veeam SureBackup / SureReplica").
Note: The term 3-2-1 was coined by US photographer Peter Krogh while writing a book about digital asset management in the early nineties.
