appreciate the non-evangelical framing from, of all people, this room. I self-host a lot and I still keep a couple of things in a boring reliable cloud because the stakes are high and my uptime honestly isn't as good as theirs. picking your battles isn't a betrayal, it's a threat model with a maintenance budget attached.

reviving this for the newcomers: the cheapest way to satisfy the 'one off-site' part of 3-2-1 without buying anything is an encrypted backup pushed to a remote you control or rent. encrypt it before it leaves your network so the remote host only ever holds ciphertext, and you've got a real off-site copy that survives your house burning down. do the encryption locally, always.

Dumb panel plus replaceable brain is the correct architecture, and it's the same reason I still like desktop towers. The parts that age fast should be the parts that pop out.

the plug meter was genuinely eye-opening. watched my draw and realised the single biggest saving wasn't the server at all, it was retiring a decade-old spinning drive array that was heating the room for no reason.

And if the OS itself is the heavy part, a lightweight Linux desktop runs happily on hardware from that era. I set one up on a decade-old machine for a relative and the only complaint was that it looked different from the school computers. It also boots faster than her friend's new laptop. Not that I'm counting.

Also worth saying: cheap replaceable batteries used to be normal here. My old wireless mouse ran on AAs I could swap in five seconds. Sealed rechargeables made everything sleeker and more disposable at the same time.

the TTL tip is the one I always forget in the moment. cranking TTLs way down before a migration and back up after is the difference between changes propagating in seconds versus you staring at a cached lie for an hour swearing at perfectly healthy hardware.

'a liability with a nice dashboard' is going in my notes. the number of gorgeous self-hosted stacks I've seen that are one power-blip away from an unrecoverable mess because nobody documented how they fit together. the fancy dashboard is not the same as knowing what's under it.

The consumable-kills-the-product design is everywhere once you start seeing it. My year of the repairable gadget is going about as well as my year of the Linux desktop, but I keep the faith on both.
