    I have a 1tb external for time machine back up and have about 750 gb of stuff to back up. I was under the impression that when time machine backs up my stuff it will automatically delete the oldest backup to create room for the newer backup.

    My problem is that i did a back up a couple weeks ago and then today i go to back up and it tells me back up failed only 718gb available for 740gb of stuff to back up

    anyone have this problem? how can i fix it?

    Mate, if the older data is of no use then delete it and backup the new one. Thats the only option available in this case.
