Okay I definitely don't have the money, time, or technical knowledge to run my own web server, even if it's just for backing up my own dumb shit, but like...why does this need to be so difficult, exactly? I have a desktop that stays turned on and connected to the internet basically all the time, so why is it not already a web server?
(Don't tell me to install Linux on my only computer unless you're willing to buy me a second, different computer.)
