5. Mirror Backup

Mirror backups create an exact replica of your data in real-time.

• Benefit: Instant updates ensure the backup is always current.
• Drawback: Vulnerable to accidental deletions or malware since changes reflect instantly.
• Best for: Scenarios where data needs to be immediately accessible.

6. Synthetic Full Backup

This advanced type creates a full backup by merging incremental backups with the last full backup.

• Pro: Saves storage while maintaining recovery speed.
• Con: Complex setup.
• Ideal for: Large enterprises with sophisticated IT systems.

7. Local Backup

Data is saved on local devices like external hard drives or NAS (Network Attached Storage).

• Pros: Quick access without internet dependency.
• Cons: Prone to physical damage.
• Usage tip: Combine with cloud backups for added security.
