First, I can repeat the 4GB size with Veeam... but vranger has again better compression Engine. 3,5GB.

Since Veeam B&R is a block-level image-based solution, all it cares is the contents of blocks. If a block is not zeroed, but has some data in it (though it might be marked as free by NTFS), it will be backed up. If you have large amount of blocks like that, those blocks get into the backup file and hence you see the large backup file size (while non image-based solutions will copy actual data only). This is why sdelete should help to obtain comparable backup sizes.

I just evaluated the different software for building a new Installation (Switch from ESXi 4.1 + Phys 2008R2 Vcenter to ESXi5.5 + Phys 2012R2) This was done at home in my freetime, your verfiy was surely in Veeam labs.
If Veeam would have support for german language, I would have no Problems to "sell" the Product to my CEO. But as he also supporting me in IT Business , he likes to have Software in German language.
That's the "Plus" for Vranger and BackupExec for example.
