GoKawiil3-2-1 backup rule adapts as storage media and ransomware threats evolve
The traditional 3-2-1 backup rule—three copies of data, on two different media types, with one copy stored offsite—is being reinterpreted by users as technology changes, with CDs largely abandoned in favor of external drives and cloud services like iCloud and Google Cloud. Reporting notes that cloud sync settings can sometimes delete files from the cloud when removed locally, and that offsite backups can still be vulnerable to ransomware if the storage device remains networked.
