System backup not possible -> Failure mounting drive

I’m currently trying to make a system backup of my cobot.

I can choose the storage location on the USB stick.
Start the backup and the cobot restarts.
After restarting, the following error “Failure mounting drive” appears.
I have already tested various USB sticks, including one from UR.
Everyone gets this error message.

What could be the cause?
What can I do to create this backup?

I had the same issue. I resolved it by formatting a new usb stick then trying the system backup again and selecting the root directory of the usb for the backup location.

Be sure to backup your usb before formatting it.
