Time Machine not backing up

I recently installed a new 4 TB ssd drive. to use as a Time Machine drive.


The drive was ejecting while in sleep.


I turned off sleep mode and reformatted ssd drive.


Now I am getting the following error:


Time Machine couldn’t complete the backup to “Time Machine”

“/usr” could not be backed up.




Mac mini, macOS 13.2
