RAID Is Not Backup: The Correct Data-Safety Stack for a Home NAS

“I built RAID, can I still lose data?” Yes. RAID covers disk failure only — not deletion, ransomware or fire. Safety is a three-layer structure.

Three layers, three jobs

RAID layer: survives hardware failure and a dropped disk, but rm still deletes;
Snapshot layer: btrfs/ZFS snapshots defeat deletion and ransomware; 15-minute intervals shrink the loss window;
Backup layer: one offsite copy per 3-2-1 covers every local catastrophe.

Simple test: a setup is adequate if it survives “the kid dragged the shared folder into the trash”.
