Can I also backup folders where Urbackup server runs?

I installed urbackup server as a docker container in my ubuntu server and the client on my Windows 10 machine. Everything seems to be working as expected now.

I was wondering if I can also backup folders located on the same machine where urbackup runs. In particular, if I can backup, say, my HOME folder on ubuntu to another HD on the same machine (in my case it is an external USB HDD). Do I need to install another urbackup client on the same machine in which the urbackup server runs already?
