alright folks, let’s get real. we all have our sprawling digital fortresses, carefully constructed brick by brick. but there’s always that one piece of software, that one perfectly tuned instance, where if it so much as hiccuped, you’d be ready to throw the entire homelab out the window and start fresh in a cave. what is it for you? what’s your absolute, non-negotiable, ‘i will personally visit the datacenter if this fails’ self-hosted application? for me, it’s my media server stack. my wife would disown me. don’t let me down, arr suite.
One thing I’d add is a whole house surge suppressor.
I saw the power lines arcing to either each other or the bamboo outside our house last week during a bad storm.
A whole house surge suppressor is only like $100, I’m gonna get one soon and install it. I saw it’s best to install it as close as possible to the main incoming power lugs, one lead on each leg of the split phase 120/240.
A UPS will protect against surges but it’s just a good idea with how many appliances and devices have circuit boards in homes these days. Like your furnace, oven, washing machine, game console, TV, etc.
I had an insane surge last winter so it’s a long time coming haha. I woke up and half my circuits were off. I measured 170v to gnd on one of the legs. Power company and fire dept had to show up to fix it.
Power is ehh not great where I live.
Edit: for your point about a NAS failure. If that were to happen, since I use unRAID, I could just throw the disks on any Linux PC and my data would be fine.
