Urbackup Ubuntu Desktop Image

I have read all the documentation that I can find. Over the last year I have installed urbackup server successfully with no problems. It seems to run fine. I have installed the client on an Ubuntu 22.04 desktop. I have only one goal. I want to run image backups of about 5 desktops and 5 servers I have in my home lab. All clients load and show up in the server. I never get any backups ever. I always end up uninstalling everything. The clients and the server seem to run great, but they do nothing. All my Ubuntu systems are ext-4 and till now, I just pull the hard drives and stick them in an enclosure on another system and do a dd image. Can this program do complete and total Ubuntu desktop/server images that can be easily installed? If so, is there a guide for how to make this work?
