Something seems wrong in my file structure

Using robocopy to back up my boot drive I got literally thousands of errors like this

Seems impossible that those paths should exist and I certainly didn't create them. Explorer refuses to let me look - Access Denied - Could it be a damaged Junction or Link ? Fixable ?

Robocopy will copy the junction as if it is a folder and will create a coresponding folder in the destination. And if the folder the junction points to also contains junction points it may lead to a path that loops to infinity, or at least until the maximum path length is exceeded for the destination.

I hit the same problem when I wrote a batch file to use Robocopy to back up my user folder (including my appdata folder). The cure was to add the /XJD option to the command line. Type Robocopy /? for help.

/XJD :: eXclude Junction points and symbolic links for Directories.

I use my batch file to perform an incremental back up of my user files twice a week, and a full backup once a month. This is in addition to my routine monthly Macrium system image. Should I need to restore a Macrium system image, then the few (if any) more recent user files can be added from the Robocopy backups.

I used /XJ which I thought was to exclude all junction points (both files and folders) - Am I wrong ?

robocopy "C:" "L:\Drive_C" /R:0 /W:0 /NS /NC /NFL /NDL /XJ /E /MOT:5 /MT:8 /XD "*Backups*" "*$RECYCLE.BIN*" "*System Volume Information*"
I use both Macrium and Acronis weekly - I am creating a Front-end for robocopy and this was just part of its testing. No junction points were copied, just a bunch of errors. I confirmed using cmd that they are nested I was able to get here:

Using cmd this is as far as it goesC:\Users\devon\AppData\Local\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data>trying again gives:"The name of the file cannot be resolved by the system."
I have not touched any Security settings

I found I needed to use /XJD. This is the problem: My user is named Owner and in my user's appdata\local folder is a junction named 'Application Data'.

That junction points to my user's appdata\local folder which contain the Application data junction, which points to my user's appdata\local folder which contain the Application data junction, which...... well.... we could follow this loop forever ... and that's just what Robocopy does.
