Hello, I'm currently using freeBSD 12.2 or something like that. There are few services running on. The question is such - how can I backup the whole system and upgrade it to 13.x latest releese and how to rollback to stable state in the case if I'll face failure. The only Idea that I have on my mind is to make the image of my hard drive from another machine and than to start upgrading,but I belive that there is more efficient way to do such backups/rollbacks on the fly without physica linteraction with my hdd. I've done some kind of such things on Google cloud platform, there I can do hot image of my current running system, and backup from this one. How can I achive something like that on my vare metal machine running freebsd.
