I have FreeBSD directly on metal, with just ZFS datastore and vm-bhyve [1] directly on it. All my services are in separate bhyve VMs. Most of those are also FreeBSD-based but some that require docker are Linux-based (my radio [2] is azuracast [3] in docker inside Ubuntu as a bhyve vm on FreeBSD). This way I can setup zrepl [4] on host to periodically snapshot whole VMs and send them to another box or to external USB disk, and I'm backed up.

Nice. I’ll have a read of those links. Thank you
