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?

Speaking from experience working at a hyperscaler - 1. cross-regional mirroring 2. Good old tape backups
