If the minimum wage was a comfortable living wage — like it should be, in my and many other folks’ opinion — then it wouldn’t matter. One person’s excess isn’t a problem, unless it’s at the expense of someone else (which, you know, is kinda the case…).
Remote backup server would be my suggestion.
Configure it with a VPN to talk to your home network and set it up at a trusted friend’s or family’s place.
I do this with a raspberry pi and an external HDD that takes daily/weekly/monthly snapshots, with daily rsync. Works nicely for me.
