Arch linux AUR clent no gui

I’ve tried to install urbackup2 no gui, because i’ve read somewhere, is the most indicated for btrfs client.
As i said i installed from AUR repo (i’m on Arch linux)
btw starting urbackupclienbackend service, gives me an error because starting it, it looks for executable in /usr/local/sbin, instead that executable file is located in /usr/local/bin.
Where i’m wrong.
thanks for assistance
