well, being on a computer over the network shouldn't bother since it's accessible with smb.
have you reconfigure exactly the same 911 backup with the same method and the same destination?
Are the archive ok? you can verifi under windows (or even linux) with a rar archive manager.
I'm working in adding some feature on that contrib and, in order to have some informations while backuping, I connect as root to the server by ssh and I lunch:
tail -f /var/log/messages
with this, I can see in real time what is running.
I think you can verifi if the share has been mounted corectly and if the restor operation is performing.
