Robocopy is failing when it is activated by clicking on my "run_bckup.bat" file.

Although the batch file has Admin-privileges, the following line fails: Robocopy "%src%" "%trgt%" .. /B ..

But starting the DOS-Window (open as Administrator) & running the same file "run_bckup.bat" succeeds!!

My Question: Is there a setting that allows me to activate robocopy by clicking on my batch-file, and the flag "/B" is used?

Here are the Robo reports for the 2 cases above.

==== 1. ROBOCOPY REPORT ON "RUNNING BY CLICKING" on "run_bckup.bat" ==== (this method failed)

Thanks, UL


The /B and /Z flags require admin rights. How you are launching them does not provide those rights, except when you are right clicking and launching as administrator.

If you want to just click and have that happen try a shortcut to your real script file with the "run as administrator" option set.

Failing that Powershell has some wonderful abilities to self escalate you might want to check out.

Or use a scheduled task.

  • @ Tim; Probably, practically speaking, the best i can expect. Many thanks. UL ( Shortcut failed..) – Uri L Jan 4 '18 at 20:56
