ZFS does have the option of storing 2 copies even on the same disk (zfs set copies=2), unfortunately it doesn't have an ECC-style option for the same disk you need to use multiple disks in which case it will transparently fix things in a RAID-Z if it can.

Alternatively, you could set up multiple partitions and run raidz across them, but performance is going to be awful.
