ZFS focus on Ubuntu 20.04 LTS: ZSys sate management After our previous general presentation of ZSys, it’s “”“time”“” to deep dive to one of its main predominant feature: state management! Why calling that state and not simply ZFS snapshots? A little technical detour first. as this question will necessarily arise, especially from those familiar with ZFS concepts. What is a state, and what’s the difference with snapshots? We have purposively chosen the “state” terminology to prevent system administrators and in general, all those familiar with ZFS to confuse if with snapshot datasets.
