This is regarding Windows Server 2012 R2 built-in backup feature (WSB),
where this server has multiple VMs installed.
With a full backup, incremental, does WSB perform incrementally inside the VMs?
Meaning, if the vhdx file of a VM has changed, does WSB - when acting incrementally - backup the whole vhdx again, or maybe it can backup only the files (inside the vhdx) that changed?...
(again, this is about a full backup, not a custom one)
