The other issue is with the data-pools. That’s more precarious since the width of corruption there can be more difficult to get a grasp on, much less address. Unfortunately, if you have backups and those backups are based of the server with bad RAM, you may find that all copies of some data may exhibit corruption.

This is possible, especially without ECC RAM that can catch bit flips before allowing new data to be written to disk.

I show an illustration of “hidden” corruption that not even ZFS or scrubs will detect. According to ZFS, the JPEG with garbled pixels or random lines is “healthy” because it matches the stored checksum on the disk.
