Personal: I run a webserver for some website (wordpress + xenforo), I've set up a cronjob that creates a backup of /var/www, /etc and a mysql database dump, then uploads it to an S3 bucket (with automatic Glacier archiving after X period set up). It should be fairly straightforward to rent a new server and set things back up. I still dislike having to set up a webserver + php manually though, I don't get why that hasn't been streamlined yet.

My employer has a single rack of servers at HQ. It's positioned at a very specific angle with an AC unit facing it, their exact positions are marked out on the floor in tape. The servers contain VMs that most employees work on, our git repository, issue trackers, and probably customer admin as well. They say they do off-site backups, but honestly, when (not if) that thing goes it'll be a pretty serious impact on the business. They don't like people keeping their code on their take-home laptop either (I can't fathom how my colleagues work and how they can stand working in a large codebase using barebones vim over ssh), but I've employed some professional disobedience there.
