While reading many of the blogs and posts here about self hosting, I notice that self hosters spend a lot of time searching for and migrating between VPS or backup hosting. Being a cheapskate, I have a raspberry pi with a large disk attached and leave it at a relative's house. I'll rsync my backup drive to it nightly. The problem is when something happens, I have to walk them through a reboot or do troubleshooting over the phone or worse, wait until a holiday when we all meet.
What would a solution look like for a bunch of random tech nerds who happen to live near each other to cross host each other's offsite backups? How would you secure it, support it or make it resilient to bad actors? Do you think it could work? What are the drawbacks?
I saw somebody suggest that the voting buttons should be used to indicate whether the comment benefits the discussion or not.
I suppose the same would be true of the original post; does the post benefit the community.
For example, posting a blog of why Mitsubishi is the best car maker to a photography forum is a downvote, true or not. Posting that veganism isn't a sustainable lifestyle to a vegan sub is an upvote, but you'd better be ready for some backlash.
