Snapshots - e.g. i had several versions of xorg.conf to play with Boot environments - saved me many times while learning about BSD Periodic data checks Datasets - are like standalone filesystems which you can tailor for specific use (use compression,...) I have TrueOS instaled on a workstation and I use ZFS raid10 for reliability. I also have offline backups, but it sure is nice not to worry about that, unless something really out of ordinary happens.
