I can not make a backup copy of all the files on my Godaddy VPS website

Hello people

I have a very strange thing. I can not back up all my files, even if I pay for that option in the admin panel of my server. My website now contains 29.8 GB of files. When I want to back up my files, at the end I see that there are only 1 GB of files.
On the support, the agent said he can not back up the ZIP files, which is fun. By the way, that yellow folder is not a Zip file, there is an image.
Can someone help me? Did Godaddy miss me or what is it about? Why do I pay for a backup if all the files on the website can not be found in the backup section?
