You're completely wrong. ZFS's scrub is both a check and a repair tool. It's already saved some of my data.

  You are partly right. Zfs scrub is a repair tool when it has parity / mirrored copy of data to recreate it.

    It's safe to make the assumption that the tool isn't magic.

    A scrub can also repair data when using `ncopies` greater than one even outside any mirrors or parity.
