I just installed Veeam Endpoint on a physical Server 2012 system. I have a large USB drive configured as my X:\. I ran a small backup job to verify functionality. It completed with an error about not being able to backup a QBB file. After the job finished I edited the settings of the job to go after a larger set of files. When I get to the Local Storage dialog it says Storage is missing but still displays the correct backup path in the Folder; section.
The drive and directory is accessible via Windows Explorer but Veeam won't see or use it now.
Running the latest version of VEB and no missing Windows Updates. My account is a domain administrator.
