A bit late reply bit maybe someone might find it handy.
Create a simple backup.bat file and put in the following text:
________________________________
@echo off
"C:\Windows\Program Files\SyncToy 2.1\SyncToyCmd.exe" -R
_________________________________
then copy this batch file into C:\Windows\System32\GroupPolicy\User\Scripts\Logoff (Note: You can activate it now just to test if it functions properly, check the SyncToy event log for errors).
Click on Run and open gpedit.msc and navigate to User Configuration then Windows Settings then Logon/Logoff, click on Logoff and click Add and select the backup.bat script that you made previously.
I hope that it work for you as it did for me.
Note. I believe that you must have Windows 7 Professional or Ultimate to be able to use gpedit.msc (Group Policy) tool.
