Getting the message "Time Machine couldn’t complete the backup to [external backup drive]

Suddenly, Time Machine is not backing up to the external backup drive


Tried everything including checking the connection, deselecting/selecting, etc


Has anyone had this problem with Time Machine with the external backup drive


Thank you for reading

Sometimes but not always the issue is not the Time Machine Backup Drive


But rather the Lack of Empty Space on the Internal Drive


How to delete Time Machine snapshots on your Mac.  


Often caused if the Time Machine Drive has not been attached  to the computer and TM Backup is set to run on a Schedule. 


TM Backup will make Snap Shot on the Internal Drive awaiting the TM Backup Drive to be attached. 


Only then will the Snaps Shots be transferred to the External Drive and deleted the Internal Drive.
