The most advanced lesson in Lucas’s book is this: ZFS protects against disk failure, bit rot, and accidental deletion (snapshots!). It does not protect against:
The master’s final piece of free advice: Send encrypted, incremental ZFS streams to a remote host every hour. Use syncoid (from Sanoid) or a simple zfs send | ssh ... | zfs recv.
That’s it. That’s the gap between "I use ZFS" and "I have never lost data." free betterbsd mastery advanced zfs pdf

But this wasn't a disk failure. This was metadata corruption in the uberblock ring. And his backup was… optimistic.
