I have a 500Gb WD external disk, which the Computor says is full ( only 20Gb remaining).

My question is why does Time machine not delete old backups to make space for new ones?

It's not serious at the moment, just annoying and I would like to fix it.

It also says that my full backup is 112Gb.

    If you upgraded the computer from one OS to another, TM cannot correctly delete the old backups. So it gets stuck.. there are other issues that cause the problem as well.. although the idea of deleting old backups is supposed to work it often doesn't.

     

    If you want to keep the existing backups.. then buy a new drive and start over. Or if it is really just a backup.. erase it and start afresh.. a new clean backup is well worth it after a lot of incrementals get built up.
