Cyber Backup in Cyber Security
The 3-2-1 backup rule means maintaining 3 copies of important data: 2 on different media types (e.g., hard drive and SSD), and 1 in a geographically separate location (e.g., cloud or offsite).
Regular backups protect against ransomware, hardware failures, accidental deletions, and natural disasters. A backup is useless if you can't recover data from it—test restoration regularly.
Backups should be automated and run on schedules (daily for critical data) to ensure consistency without requiring manual intervention. Offline backups prevent ransomware from encrypting backups.
Different data requires different backup frequencies: daily for financial records, weekly for personal files, monthly for archives. Critical business data may need hourly backups.
