I have a Buffalo QUAD Linkststation. I use mapped drives. I am trying to backup specific folders on the NAS but I always get the same error using network or mapped drives. I am using TI Workstation build 8163. E00040019: Failed to backup file or folder 'music'. Failed to backup file or folder. (0x40019) Path = "\\?\UNC\Nas1\music", Hints = 1) Tag = 0xA8A1022BD18AE0C9 The request is not supported (0xFFF0) code = 80070032) Tag = 0xBD28FDBD64EDB8AF If I try and backup the drive map I get M:\ not found. It sees the drive map when I select the drive for backup but once the backup starts it fails.
