I use https://mycorrhiza.wiki/. It is really lightweight and stores data in a git repo. So it is terribly easy to export and backup it. the only drawback is that it uses its own markdown dialect

It was a huge codebase in c# with a single file in VB.net with a comment at the top "copied from codinghorrors.com/…". I never dared to try understanding what that file was supposed to do and why nobody bothered converting it in c#

I have an initramfs script which knows half decription key and fetches the other half from internet.

My threat model is: I want to be able to dispose safely my drives, and if someone steals my NAS needs to connect it to a similar network of mine (same gateway and subnet) before I delete the second half of the key to get my data.

How frequently do you send these updates? Most of dynDNS provider rate limit the updates you can send, so it is possible that you send a bunch of useless updates when the IP didn't change and the actual update that is required gets discarded because you hit the limit.

Do you log your script errors somewhere? Are you sure that the IP changes so frequently?

I know at least 3 European fiber providers which offers static IPs. For broadband always on connections IP changes should be pretty rare

It is not just a matter of how many ports are open. It is about the attack surface. You can have a single 443 open with the best reverse proxy, but if you have a crappy app behind which allows remote code execution you are fucked no matter what.

Each port open exposes one or more services on internet. You have to decide how much you trust each of these services to be secure and how much you trust your password.

While we can agree that SSH is a very safe service, if you allow password login for root and the password is "root" the first scanner that passes will get control of your server.

As other mentioned, having everything behind a vpn is the best way to reduce the attack surface: vpn software is usually written with safety in mind so you reduce the risk of zero days attacks. Also many vpn use certificates to authenticate the user, making guessing access virtually impossible.

Ikea and Lidl zigbee work well for me and are reasonably cheap. Ikea's look a little better, but I have only one because it is a pretty recent product.

I have automated it with a small initramfs script which has half password and download the other half from internet. My threat model is to protect from a random thief. So they should connect it to a network similar to mine (same netmask and gateway) and boot it before I can remove the half key from internet.

some security which is on my TODO list is: allow fetching the half key only from my home IP and add some sort of alert for when it is fetched.

The really important things (essentially only photos) are backed up on a different USB drive and remotely on backblaze. Around one terabyte cost 2-3$ per month (you pay by operation, so it depends also by how frequently you trigger the backup). You want to search for "cold storage" which is the name for cloud storage unfrequently accessed (in other words, more storage than bandwidth). As a bonus, if you use rclone you can encrypt your data before sending it to the cloud.

Backup and encryption. encryption prevents the thief to see my data, backup allows me to make a new server. Furthermore, as other pointed out, I don't expect that a common thief will see a lot of value in a small black box on top of a shelf

I remember reading a post on mastodon where it was explained that no mother board validates the secure boot keys expiration dates otherwise it wouldn't boot the first time the BIOS battery gets empty and the internal clock gets reset. The post was written well and was citing some sources. But I didn't try to verify these assertions.

I'm not familiar with this setup. But do you want for the server to boot as soon as it receive any packet addressed to its IP?

You need to send the WOL packet to the broadcast address of your network, not to the machine IP address. It this way all the machines on the network will receive it, including the ones that have been powered off for a while
