Is it possible to remove a folder from a container/vm backup?
I have an external share mounted inside the container's /mnt, and I wanted to disable the backup of this folder.
No and I hate that it works on a container. I'm happy that it works with the proxmox-backup-client when doing backup to PBS from the inside, but it really isn't what I want when doing a backup from Proxmox. The container should not be able to interfere with my "external" backup! But I'm glad that it does work for you.
