Ask HN: Looking for secure modern low energy local backup device

I used to have a TimeCapsule to backup my MacBook but I do not fully trust it anymore.

Does anyone have a good hardware recommandation ?

I was looking into this, but it seams mostly build for video recording. Not sure it has NAS capability. https://store.ui.com/collections/unifi-network-unifi-os-consoles/products/unifi-cloudkey-plus
