I didn't change a user, so bareos should be right. I have the following output:
root@backuptest:/etc/bareos# ls -la
insgesamt 48
drwxr-xr-x 7 root root 4096 Nov 22 12:31 .
drwxr-xr-x 110 root root 12288 Nov 22 12:37 ..
drwxr-x--- 15 bareos bareos 4096 Nov 22 13:25 bareos-dir.d
drwxr-x--- 3 bareos bareos 4096 Nov 22 12:31 bareos-dir-export

drwxr-xr-x 6 root bareos 4096 Nov 22 11:03 tray-monitor.d
and
root@backuptest:/etc# ls -la
drwxr-xr-x 7 root root 4096 Nov 22 12:31 bareos
drwxr-xr-x 2 root root 4096 Nov 22 12:37 bareos-webui
looks for me (linux beginner) like bareos is the owner of the folders.
