How do you ensure redundancy of your file server?

If you have multiple node webapps all uploading files to a single file server (e.g. nginx), how do you ensure redundancy of that file server? You can have RAID on that file server to help minimize the risk of data loss, but if the whole machine gets destroyed, you're out of luck.What strategies can be used to ensure redundancy of files across physical servers in the same data center, or perhaps even across data centers? It seems risky to only have 1 file server.I could take regular rsync backups to another server in a different data center which would probably be good enough, but if I needed to restore from that backup file server there would be an inconsistent view of the files. Some files would be partially uploaded, and others that would be expected to be present by the application weren't included in that backup.What are some options for handling this?
