There's no local that can't be replaced, you would either fix the hardware and get the host back into the cluster or just rebuild. If you have Enterprise Plus, you can rely on host profiles and all you would need to do is get the host networked and any further customization can be handled by host profiles. You could also periodically backup your host configuration (not VMs) and if you have host crash but you're able to fix the hardware and needed to rebuild and apply the most recent backup you can do so with this script: ghettoHostBackupManagement.pl

Thank you, that answers my question. I don't have Enterprise Plus, so I'd still have to reconfigure the server (or restore from a backup - thanks for the info there). But the key thing is that there's nothing I can't regenerate, so I don't need to worry about making sure the server's local storage is redundant.
