Trouble backing up Mapped Drive

I have reviewed many of the threads in this forum but have not found a solution to my issue.

I am running ATI 2015 on a Windows 7 Enterprise laptop. My office has mapped network drives ... one of which is for personal use. I am trying to use ATI 2015 to backup this drive to a Seagate 3TB USB external drive.

I have been using the UNC address \\FILESERVE\personal\MPD\Test\ which is the correct UNC address and is directed to a test folder on my (MPD) personal network share. The Test folder contains a single .pdf file that is about 2.5MB in size.

Images of the setup screens are attached and include an image showing the UNC path being used (FIG 1) and the setup screen with the target device (FIG 2). Setup in this manner, it appears that everything is in order to initiate the backup.

After just a few seconds, an error screen pops up indicating that True Image "Failed to back up file or folder 'C:\globaldata.ini'. An image of the error screen is attached (FIG. 3). I select "IGNORE" and the backup proceeds. (Please note that the folder being backed up does not contain a globaldata.ini file.)

After about 10 minutes, the True Image window indicates that 20+ GB have been processes and that there is almost 2 hours of backup time remaining, as shown in the attached image (FIG. 4) About 20 minutes after starting the backup process, the TI window indicates that 40+ GB have been processed and that 3-1/2 hours remain.

I have only once allowed the process to run for the full duration ... which was left to run overnight so I am unsure exactly how long the process took. However, the resulting backup was of a drive other than than that including the "Test" folder.

I expect this is an "operator error" situation, but am unsure about what else to try. I do not have permissions to alter any settings for the network drives.

Any assistance would be greatly appreciated!

[UPDATE] The above described backup was allowed to proceed to completion. The process took approximately 5 hours and resulted in a backup file of approximately 700 GB in size. The resulting backup file included an odd combination of files from the local hard drive (C:) and what appears to be a full backup of the external USB drive (D:) onto which the backup file is being saved.
