Time Machine logs

Where are the log files from Time Machine backups saves?

You can see the TM log file from the terminal.app copy and paste:

printf '\e[3J' && log show --predicate 'subsystem == "com.apple.TimeMachine"' --info --last 6h | grep -F 'eMac' | grep -Fv 'etat' | awk -F']' '{print substr($0,1,19), $NF}' 

This was very helpful and gives me a great start to determine when something happened. Thank you.

Good computing jhtoppin !
