Ghost V15 backup on SkyDrive

I made a network mapping to my SkyDrive on my computer and would like to use this drive as my backup location for Norton Ghost v15. When I start the backup job, Ghost asks me for logon credentials, although the network drive is connected to my computer and credentials are authenticated. This is because the system runs the backup service as the local system account and needs to provide the logon credentials again to gain access to my SkyDrive. However if I provide my loginname (which is my hotmail emailaddress) and my password, the logon fails. Closer inspection of what is happening shows that Ghost is reformatting my loginname from [Removed] to [Removed]. Also in the option screen - destination details Ghost applies the same "intelligence", which I'm guessing messes up the logon. How can I workaround this problem, or am I doing something wrong?

Thanx!
