I run it on my work desktop with two single disk pools. It's a bummer
when a sector goes bad and I can't get to a file, but I would rather know
the data is bad than silently read bad data. This has happened twice now,
both in backups, so I just wiped the bad file and let it re-copy.

By default ZFS already stores an extra copy of metadata.

I think copies= controls the copies of data. Bumping it up does increase
metadata redundancy, but I don't see a way to only increase metadata
