I have to admit that zfs had me at their extreme data integrity and I've
actually never done anything with any of the advanced features. I'm not
even spanning volumes or anything like that, I've pretty much just moved
primary storage to zfs and left the backups as routine consumer NASes. I
figure that if something goes wrong on the server, I still have no-fuss
access to the files.

You just reminded me of something: A couple years back I converted a
pile of FLACs to ALAC for someone else, only to learn that the ALACs
were somehow corrupted. I wound up writing a script to obtain the FLAC
checksum, convert the FLAC to ALAC, then convert the ALAC to another
FLAC, get the checksum of that FLAC and compare it to the source file's.
You can already guess the punchline: Now that I can catch corruption
immediately, I've never seen even a single failuare.
