Backup single disk of a VM

Do you want to backup only one of the two disks, or both? I'm not sure what you mean by separately.
I mean to create a cronjob that backup only one disk is the virtual machine.
The vm is disk is backuped by proxmox 3 times for day, but the second raw disk is big, 4tb, I want to backup only every week.

In the vm preferences the second big disk is unchecked from the backup.. but from the proxmox cluster backup routine I can't select which disk of a vm will be backuped.

Thank you.
If the disk is excluded, because of the option in the VM config, it will not be backup up. There is unfortunately no option to backup disks on a specific schedule like, on Monday only one disk and on Tuesday all disks.
