I run Windows Server backup on Windows 2012 Server running Hyper-V and also on SBS2011 (Standalone, no hyper-v) in two physically separated environment.
As seen in the screenshots above, I noticed that Windows 2012 Backup takes the same amount of time and it performs FULL backup every day whereas in SBS2011 it does incremental backups and the amount of time that it takes varies from day to day.
So my question is
(1) why Windows Server backup in 2012 Server does FULL backup instead of incremental backup? I rather like to see "incremental backup" because it takes a shorter amount of time.
(2) On W2012 / Hyper-V screenshot, FT1 is a VM. The D drive is where all the files related to VMs are stored. So the size of D drive is 382GB which is understandable because I have multiple VMs. But how come FT1 (which is about 300GB in size) shows 0KB?
