I got a job, where I do backup my games folders to my profil folder on a server. Clue is this:
Source:
D:\Games
E:\Games
Target
\\Server\Backup\Profile\
Incremental, use attributes (also tried without), Mirror task, Always create top parent folder, clear archive attributes
Now, after it does the E: drive - it emty the content that is backuped from the D: drive.... It dont count all the folders and do a total compare...
As it is now, I have removed the E: from source.
