    There’s a better way. Here in Finland it’s pretty common that you can just call/text your boss that you have a common cold and you can be on a sick leave for few days (3 days is pretty common limit) just self-diagnosing it. With longer sickness you’ll need a doctors note, but at least on my company with common cold and other minor stuff it’s taken care of either over text chat or via a call with a doctor.

    Obviously if the doctor thinks the whatever you have requires more in depth examination they can schedule a meeting, but for seasonal flu and stuff like that it’s pretty rare you need to see a doctor in person at all. And of course they’ll follow the numbers, so that if you call in sick every monday or whatever the rules are more strict and examinations are done more frequently, but for vast majority a few days laying in bed with a fever isn’t any kind of issue.

    There’s plenty more reasons than filesystem corruption to use clean shutdown and even just plain UPS without any status information to the host. I haven’t seen a full drive corruption due to power loss ever. Various levels of corruption, yes, but not ‘all the data is gone’ scenario due to filesystem being broken. But I have seen multiple hard drives which have died on host shutdown without any warning (no smart errors or such), after power loss they just refused to start again.

    Just today we had multiple short (~30 second) power outages and without UPS that would’ve put considerable strain on my hardware. Gladly those are pretty rare and those were well short enough that my UPS kept the system running, without one that would’ve meant that my hypervisor would’ve crashed and that would’ve resulted on several unclean reboots for the VMs.

    Also, back to filesystems, with selfhosting, some kind of hypervisor is often in the picture, so the drive activity is generally much higher than with single workstation and corruption on a single file or some part of filesystem is way more likely. Total data loss is pretty unlikely, but a corrupted VM image can be a pretty big deal, regardless if it’s filesystem or single file which is the main issue.

    there’s no standardized mechanism for forcing applications to save

    On Linux (and I guess BSD and other *nix variants) there is. SIGTERM is exactly for that situation. Sure, programs can choose to ignore it, but I don’t think I’ve ever seen at least any FOSS software which wouldn’t respect that. Of course the program might crash and cause loss of data, but the mechanism is there.

    You’re of course generally correct about modern filesystems being more resilient to power loss, but they’re not immune to problems and also you’ve omitted a large chunk of other reasons why people like to have UPS on their system, with or without monitoring them.

    For me personally the hardware is least interesting part of running a homelab. I’d happily run everything on VPS if there was no constraints on money or bandwidth (among other things). But as the limitations are there running things on my hardware is a necessary evil and for that an UPS or two are practically must to have to prolong life span of hardware and prevent data losses. Of course that’s just one box to check on the stack, but when planning for a home server setup for anything I’d say it’s a pretty vital part for the whole setup.

    Modern filesystems can corrupt as well with unclean shutdown. They are just less likely to do so. My server stores photos of our life over couple of decades with other nearly irreplaceable data so having the UPS and clean shutdown on power loss gives at least some confidence that the files stay where they are.

    Of course I also run backups of the data, but it’s another layer on data safety setup.
