Hello frietch2,


Welcome to Apple Support Communities!


If we understand your post correctly, Time Machine stops when attempting to backup to an external drive with a message that says the disk is full when you know there is space available. We're happy to help!


Did you check the article that you came from to ensure that the external hard drive you're using is compatible?
