I use Backblaze B2 through my Synology NAS to offsite my important data. Most things though I just backup locally and accept the risk of needing to rebuild certain things (like most of my movie/TV media files since I can just re-rip my physical media, and the storage costs are not worth the couple of days of time in that unlikely case).
I really think this is key when thinking about your backup strategy that is specific to self hosting compared to enterprise operations. The costs come out of our pockets with no revenue to back it up. Managing backups for self hosting IMO is just as much about understanding your risk appetite and then choosing a strategy to match that. For example I keep just single copy in B2, since the failure mode I’m looking to protect against is catastrophic failure of my NAS which holds my main backups and media. I then use Proton Drive and OneDrive to backup secrets for my 2FA setups and encryption for my B2 bucket. This isn’t how I would do it at work (we have a fair more robust, but much more expensive setup). But my costs for B2 are around $15/mo which I am fine with. When I tried keeping multiple copies it had grown to over $50/mo before I cared enough to really rethink things (the cost of the hobby I told myself).
I think this is a huge part of it but there is certainly a lot of nuance here. We have a phenomenally funded, equipped, and trained military, but in the last 20 years it’s been shown to be only moderately effective at addressing the threats in the world that have a small fraction of the resources our military does with few exceptions (naval might is probably the largest of those exceptions). So even problems we think we should be able to solve we barely can.
There is also large and growing wealth disparity which drives the tribalism deeper and makes many folks dig their heels in to positions that just aren’t based in reality (see anti-vaccine and lockdown sentiment around COVID as but one example). Couple this with the majority of Americans being truly terminally online and being stuck in echo chambers that just further ingrain the basis they hold and it causes a lot of vocal Americans online to lash out irrationally.
I would like to offer OP a view that we aren’t all like this though. For many of us our incoming government, the corrupt people they are tagging to lead our various institutions, the incomprehensibly rich heads of various companies, and the brainwashed cults that worship them all are sources of deep shame. I can only speak for myself, but my friends, close coworkers, and even a few of my family all feel this way. Please don’t write off all Americans because of the loud, obnoxious jerks you have to see in many places, some of us are pretty decent people that really want to make the world a better place and help everyone we can.
