Airgap+

[ColHut]

Whilst I understand the router’s role in the Airgap+ backup plan, I wonder if there is a local switch that could also help isolate the backup automatically for local jobs.

Or perhaps no software should be trusted to provide the airgap

Hmm, I'd not heard of this product until now.

What is Airgap+?

Airgap+ works with QNAP's QHora routers to manage link up/down status, creating a logical air-gap between NAS systems. Specifically, QHora routers only allow network connections when the backup job is executed from the source NAS to the destination NAS. This ensures that data is only transmitted when necessary while blocking external network access.

Whilst I understand the router’s role in the Airgap+ backup plan, I wonder if there is a local switch that could also help isolate the backup automatically for local jobs.

If you're using a correctly-configured QHora router, then why do you need a switch?

Or perhaps no software should be trusted to provide the airgap

Well, I agree with that. An air-gap is supposed to mean: not physically connected. QNAP are trying to create a pseudo-air-gap (which sounds like a good idea), but I wouldn't trust it.

Thanks OneCD,

I don’t have a Qhora router but the idea got me thinking about options for the LAN. I am not as good as I should be about unplugging by external backups…
