At least for some android phones this is already possible with Lineage OS.

NUCs make really nice homelab servers. They can give you a lot of power while not sucking too much electricity. I have used three NUCs to build a kubernetes cluster and I’m very happy with them.

The only thing that made me buy additional hardware was the need for 10Gb Networking and more internal storage, which I couldn’t realize with my NUCs. I also learned to love the IPMI feature of server motherboards, that NUCs don’t offer afaik. I would recommend to use a hypervisor like proxmox which makes it easy to spin up new servers inside virtual machines - this way you don’t have to re-install your OS on the NUC everytime something goes wrong or needs to be upgraded.

Generally a NUC is a great device for a homelab, especially if you’re just starting out!

Since you’re also located in germany, I’d like to share a site I found when I was looking for my own router based on OPNsense: NRG Systems. Some of their models use pretty old hardware, but I got the IPU651 with the 19" chassis and I really love it.

Use something like pgAdmin, DBeaver or the pg cli to connect to your postgres instance. Then run the command from the changelog as a SQL query.

You can get a quick overview via DSM, I think in the Disk Manager. For more details you could jump into a terminal and use smartctl.

Have you checked the SMART values of your drives? Do they give you a reason for your concerns?

Anyhow, you should never be in a position where you need to worry about drive failure. If the data is important, back it up separatly. If it isn’t, well, don’t sweat it then.

Why would you buy something new if your current solution works and your requirements don’t change? Just keep it.

Wasabi S3 is nice and cheap. You’ll only pay what you use, so probably just a few cents in your case.

Oops, nevermind:

If you store less than 1 TB of active storage in your account, you will still be charged for 1 TB of storage based on the pricing associated with the storage region you are using.

I have no experience with terraform but Bitwarden has an API and CLI, so you might be able to script something with it?
