Advice for tiny NAS to store backups? (lemmy.world)

My backup game is pretty bad, I only have my primary copy of my data and a cloud storage copy. I was trying to think of a cheap way to have another backup, and then realized I have an Orange Pi Zero 2 and a 1TB USD SSD lying around. So I was thinking of:

installing Debian on the OPZ2, and setting up key-authenticated SFTP (no password auth)
connect the OPZ2 on my home network and expose a non-standard (e.g. not 22) port for SFTP
have a subdomain point to my home network ip, and use DDNS to keep it in sync
using Restic to remotely push password-encrypted backups to the OPZ2 via SFTP using the subdomain
set a cron job to check diskhealth and send myself email on bad
enable auto updates on debian and email on fail

Is this setup a bad idea? Is this a security nightmare? Any better suggestions?

Hi,

maybe use openwrt, it’s meant by to be used on cheap low end devices, don’t know how good the image is. https://github.com/Kazagumo/openwrt-orangepizero2

I personally use it on an discontinued WD mybook live duo. If you prefer an easy setup, be warned, it is not. ;) On the plus side, openwrts Luci is a good starting point for configuring of a lot of services, hdd spin down, monitoring, etc.

Use case: samba4, kopia destination from my VPS through Zerotier

Good luck with your setup!
