I setup a new CENTOS 7.4 and I can backup mysql sql files. But i can not backup domains or virtual servers. I have done the schedule backup exactly as per other server o centos 6.9 with same ver of virtualmin and that works but this new one is giving errors. It only saves one file virtualmin.tar.gz of small size but there is nothing else.
