There exist a number of storage systems with advanced, RAID-like features, including ZFS, btrfs, and Ceph. On the surface, features of these systems, like snapshots, might give you the illuson of additional protection, but don't be deceived. Even the smartest most advanced storage engine is still susceptable to at least one, and almost always several, fatal failure modes that can destroy your data.

Just like RAID, advanced storage systems still aren't backups.
