I made a backup of a virtual machine (VeeamZip to ...) and supposedly the backup was successful. But in reviewing the returned file, only weighs 16454 KB, when the VM weighs 100 GB. When I make a backup of another virtual machine of the same size, I returned a file of at least 9 GB. I think it's a mistake, but tell me Veeam was successful. You see the backup was done in 1 minute.
What am I doing wrong?
