There exists a number of file and storage systems with some advanced, RAID-like features. These include ZFS, btrfs, and Ceph. On the surface, these might give you the illuson of protection, but don't be deceived. You can still trash your whole system (or cluster, for Ceph). You can still `rm` files or other destructive commands. A fire can still destroy your whole rack.

Like RAID, ADVANCED FILESYSTEMS STILL AREN'T BACKUPS!
