WP_SITEURL WP_HOME in different folder

Excuse me,may I ask if my WordPress is installed in different folder,is there any way that I can backup the whole website?

WP_HOME:./ (.htaccess robot.txt etc.)
WP_SITEURL:./wordpress

I want backup both of them.
I tried “Additional Files/Folders” function, but it didn’t work.

Inside backup.zip only those files in “./wordpress”.
