Airgap+
Physically isolates backup NAS from the public network, delivering maximum security and stability against cyber threats.
What is Airgap+?
Airgap+ is a feature of QNAP’s Hybrid Backup Sync (HBS 3) to achieve air-gapped backups.
- Airgap+ works with QNAP’s QHora routers to automatically control the link up/down status between NAS devices.
- Connectivity is enabled only during backup/sync jobs and is disconnected immediately after, minimizing network exposure.
Why is Airgap+ effective?
Disconnected by default
The backup NAS remains isolated from all network access—except when temporarily connected for scheduled backup jobs.
Physically isolated
Provides the most secure and stable protection with network isolation.
How Airgap+ works in real life
Explore how Airgap+ is deployed in real-world enterprise environments.
Case 1
Standard
Run a backup job on the source NAS with Hybrid Backup Sync. QHora permits connections with the backup destination NAS only during the backup process, blocking all connections at other times.
Case 2
Advanced: Backup via bridge NAS
In this setup, the QHora router blocks access from the main file server to the destination NAS, enabling it to totally isolate the destination NAS within a secure Intranet. Also, backup operations are centralized on a bridge NAS to conserve the main file server’s CPU resources.
How it works:
Why should businesses use Airgap+ with QNAP NAS?
-
High-speed access
QNAP NAS supports 10/25/100GbE connections, significantly accelerating data backup and transfer processes to minimize downtime.
-
Rapid data recovery
The high-speed infrastructure enables faster data restoration, helping businesses quickly resume operations after unexpected disruptions.
-
Immutability
With the ZFS-based QuTS hero operating system, once data is written, it cannot be altered or deleted. This provides strong protection against ransomware and human error.
-
Expandability
QNAP NAS offers flexible scalability through hot-swapping drives, connecting expansion units, or migrating to models with more bays—ideal for growing storage needs.
-
No manual effort
Airgap+ eliminates the need for manual removal and offsite storage. Backups run automatically and securely.
-
Power control
NAS devices can be remotely powered on or off, allowing greater control and convenience—especially in distributed or unmanned environments.
