Backup Size vs Windows Backup

[Morgenstern72]

Windows 10 Pro 1709 and veeam agent for Windows 2 (downloaded 2 days ago).

With the same folders (Backup collects data from several folders on 3 disks selected) and different targets (both 2TB external USB3 HDs, same manufacturer and model) this happens:
) Windows Backup and Restore (Windows 7): backup size 469GB, System Image 124GB
Runs for some hours (over night) and can backup everything including the system image

) veeam Agent for Windows 2: Backup Size "?", System Image 193GB
It stopped with different errors:
First try: Target too small (Free Space 1.2TB) since backup size is estimated 2.4TB (not, its not)
Second try (excluding a big folder just to see what happens now): it stops with the error, that it cant access any folder on the D drive and cant find the selected folder on the S drive
It ran for hours and at the end had two files on the target: one small with some kb and one "big" with 32GB.

The target that veeam uses is also used for file versioning in Windows 10, which works fine.

So what do I do wrong? I work with veeam in the office and have no problems. At home it seems to at completely crazy and the config semms to be super simple).
