Still has nothing to do with Time Machine.
You do a backup before the upgrade. Then your phone data is current on your Mac.
If the upgrade fails you can restore to factory then restore the last backup.
For Time Machine to play any part in it you'd first had to have backed up your phone, then run a Time Machine backup on your Mac, then the upgrade would have to have toasted either your phone backup or borked the entire box requiring you to restore from Time Machine.
