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 run other destructive commands accidentally. A fire can still destroy your whole rack. A malicious user could overwrite your database. Even the smartest most advanced storage engine is still susceptable to at least one, and almost always several, fatal failure modes.

Like RAID, ADVANCED FILESYSTEMS STILL AREN'T BACKUPS! Just make another copy of the data, okay!?
