I'm using Backup & Replication 9.00.902 to make a single VeeamZIP backup of a Linux VM on a vSphere 6 server. The VM is powered off. Its works fine but I was wondering why the resulting .vbk file was so big. The VM's disk size is about 160GB, the Used space with the OS is 78GB. The resulting .vbk file is 133GB. Why is VeeamZIP backup up empty space? Shouldn't the resulting backup (.vbk file) be a max of 78GB, or more like 50GB because that becomes compressed/ZIPed?
