Backup Connection Error

Thanks for all your comments. They helped this Lurker figure out my similar issue. I right clicked on my extra drive (F:) and it was set to share by default, which confused me, because I could not get it to connect to backup. Then I saw the "New Share" option and gave it a new name (Storage) and set permissions to full control. Now I just type my computer name in at "Host" and at "Path" I type in "Storage" and I am connected sucessfully! BTW, after setting the new name of "Storage" it was replaced on the open window with F$, but available to view in a drop down.

I am trying to set this up to back up to my 1TB internal HD so I can then backup to my cloud service which does not offer NAS interaction.

Update: For the new folks (like me)... I have to remember that even though the "Test Connection" event in backup returns a succesful response, you must include an ID: ("Administrator" typically) and Password:(Whatever your computer login) for the backup to complete sucessfully.
