Unable to backup to SmartDisk with stage and store located on UNC attached storage -
Description
Cannot backup to SmartDisk with storage pools hosted on ExaGrid NAS.
SmartDisk superserver trace shows there are problems modifying directories, deleting files and accessing meta data.
Reinstalling SmartDisk shows not all files are removed from stage and store locations.
Truing to delete the files manually fails.
Checking SmartDisk user access to the configured UNC paths on the Exagrid NAS storage appears correct.
