Backup and Recovery
Processes for creating and restoring copies of data to prevent loss due to cyber incidents.
Understanding Backup and Recovery
These strategies are essential for ensuring business continuity and preventing data loss due to system failures, human errors, or ransomware attacks.
Types of Backup Methods
Full Backup
Creates a complete copy of all data.
Requires more storage and time but ensures comprehensive recovery.
2. Incremental Backup
Backs up only changed data since the last backup.
Faster and requires less storage.
3. Differential Backup
Backs up data changed since the last full backup.
Balances speed and storage efficiency.
Best Practices for Backup and Recovery
Follow the 3-2-1 backup rule (3 copies, 2 media types, 1 offsite).
Regularly test backups to ensure successful restoration.
Use encryption to secure backup data from unauthorized access.
