Time Machine stops backing up after alert: " some files cannot be copied"

My Time Machine will back up most of my data until running into an alert that "some files cannot be copied" then it stops without completing the back up. Is there a way to identify these files it cannot copy?


Thanks for your help

Mac mini, macOS 11.3

Not that I know of. But you might try booting into the Recovery volume (boot with the Command + R keys held down), select Disk Utility and run First Aid on your data volume. If you get any errors rerun First Aid till you don't. Then reboot normally and start a fresh TM backup. See if that will get thru the problem.
