I’m just a small business & homelab guy, so I’ll probably never use one of these big distributed file systems. But when people start talking petabytes, I always wonder if these things are actually backed up and what you use for backup and recovery?

Well, for active data, the idea is that the replication within the system is enough to keep the data alive from instance failure (assuming that you're doing the proper maintenance and repairing hosts pretty quickly after failure). Backup and recovery, in that case, is used more for saving yourself against fat-fingering an "rm -rf /" type command. Since it's just a file system, you should be able to use any backup and recovery solution that works with regular files.
