ZFS already stores three logical copies of all metadata, regardless of copies parameter or vdev redundancy. The failures LTT experienced went way beyond what ZFS, or btrfs, could repair. They made severe errors in judgment when setting up the system and failing to monitor and administer it. No system will ever protect against this. Not ZFS. Not btrfs.
