Is zfs able to repair from single data (copy) corruption?
My main issue is to be able to repair a "silent" data corruption on a single drive machine. Am I able to use x% of my "partition" to data repair or do I need to use other partition/drive to mirror/raid it?
If I understand right zfs can detect bitrot ("not really" a big deal) but without any local copy It can't self heal.
My use case is an arm A20 SoC (lime2) to storage local backups among other things, so I need something that detects and repairs silent data corruption at rest by itself (using a single drive).

A poor man NAS/server. ;)
