Still struggling with rsync

I've tried a few times to sort this, but I just can't understand why this doesn't work so thought I'd ask some experts.

I have 2 HP micro servers running 9.2.1.8, both with 16GB ECC RAM but with a slightly different volumes:

freenas1 (192.168.168.65) has 4x4TB drives with a RAIDZ1 volume and 3 datasets (media, home, backup)
freenas2 (192.168.168.165) has 1x4TB and 3x3TB drives striped with the same 3 datasets

I want rsync to run automatically pushing changes on 1 to 2. I've used the rsync...
