I upgraded to Yosemite yesterday, and just now I got a Time Machine alert

Disk is Full

although there are 350+ GB on the backup disk according to Finder. It said it had deleted an old backup (boo).

Just now I did a manual backup (from the TM preferences panel) and it backed up 2 MB to the free 350GB disk and all was fine.

What gives? What can I do to make TM happy?

  • If you have already a Mavericks backup on it, perhaps you have some conflicts. You have tried to erase your disk ? – StrawHara Oct 19 '14 at 5:51
  • It's not clear if you are looking to clean up the backups or do something else. Could you edit this if you still are facing this issue? – bmike Jan 31 '16 at 15:14

If on top of your Mac's hard drive, you are also backuping an external USB drive, you may want to check this thread: https://discussions.apple.com/message/27031297


Try to open Terminal (use spotlight) and type sudo rm -Rf (Directory to disk)/*

    You should explain what that does – user151019 Jan 31 '16 at 13:23
  • People - please don't sudo rm -rf anything unless you have a backup and time to reinstall your Mac. This person is just evil for suggesting you delete your entire system... – bmike Jan 31 '16 at 15:10
  • What it is doing is it is deleting the disk, Back it up first but it helps because backup drives like to hide extra crap that you cant use – gidoBOSSftw5731 Feb 22 '16 at 16:35
