The function itself is working (I just made a backup) but I can not see any output of the scripts.

Research direction

Start by reproducing the panel action and inspect /var/www/ncp-web/index.php at line 276, where PHP reports an array-to-string conversion. Then examine /var/www/ncp-web/backups.php at line 33 and the related permission and TypeError logs; done means the panel displays script output after the upgrade without these errors.
