I am doing system state backups on a Windows Server 2008 R2 Enterprise (Service Pack 1) machine and expected the backups after the first one to be incremental. However with each backup a new directory with vhd files are created and the vhd files are almost the same size as the with the first backup. So the backups does not seem to be incremental.
I used the following command to do the backup:
wbadmin start systemstatebackup -backupTarget:f:
I played around with the settings under "Configure Performance Settings" in the Windows Server Backup plugin in Server Manager but according to the description at the top of the dialog these settings are not applied to system state backups.
Are there any settings available for wbadmin system state backup to make the backups incremental?

The incremental backup will work when you assign a dedicated disk that will be formatted by the Windows Backup Software. If you use a shared location each time it will run will create a new full backup!
