Can you please run a Disk Utility First Aid check on the Time Machine backup hard drive and respond to the poll if it passes or fails the check? This is for users of Big Sur 11.5.2 and you use spinning disk hard drive(s) for TM backups. Please also indicate the type of Mac you have (e.g., 2013 Mac Pro, 2019 Mac Mini, etc.) Please do not respond if you run a different version of MacOS or you use SSD for backup.
Ever since I updated the MacOS to Big Sur 11.5.2 on my 2013 Mac Pro (Trashcan), I have run into this issue. I have tried 3 HDs and they all failed. They are directly connected to my Mac Pro. The error message looks like below:
