Hi,
I'm Sumit, here to help with your query on the Microsoft Q&A forums.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
The entire problem lies in the Backup system for Windows. Microsoft deprecated it years ago and recommends migrating to a third-party solution.
Maybe you could find something in the event log.
To access these logs, follow these steps:
Click on the Start button.
Type Event Viewer
into the search box and press Enter.
In the Event Viewer window, on the left-hand pane, navigate to Applications and Services Logs > Microsoft > Windows > Backup.
Within the Backup folder, you will find an Operational log. This log contains informational events about the backup service starting and stopping, as well as any error or warning messages related to your backup and restore jobs.
Moreover, if you use custom settings, you may want to uncheck any included (checked) folders that have been deleted or moved.
I hope you find this information useful. If you have any more questions, don't hesitate to reach out. Otherwise, please take a moment to accept the answer. Wishing you good luck!
