Yes (although ZFS is pretty stable, it is always good to mention to not put all your eggs in a single basket).
My fallbacks are:
- an external drive that I connect once a year and just rsync-dump everything
- for important files, a separate box where I have borg/borgmatic [1] in deduplication mode installed; this is updated once in a while
Just curious: Do you have any reason to believe that such a data corruption bug is likely in ZFS? It seems like saying that ext4 could have a bug and you should also store stuff on NTFS, just in case (which I think does not make sense..).
