Hi Peter,

Everything that Time Machine does is logged to the system log, so it is 
possible to get more detailed reports on its activities. 
Open Console in Applications/Utilities
To find the activity for Time Machine, you only need to know that the Time 
Machine process is called backupd. 
Click in the search box at the top right of the window (or just press 
Command-Option-F), then type backupd as you type, Console will filter the 
results to only show those entries related to the backupd process. 

The filtered output results are shown in three columns and it’s the Message 
column that’s most useful. The messages reveal how much data was backed up, 
what older backups were removed, and other general information about the backup 
run.

Kind regards,

Ronni
