I have had my mac book pro for almost 6 months. Whilst using a 500 gb portable hard drive with time machine, I was surprised to get a message saying there wasn't enough disk space to complete a back up.
I brought another but started to look into why I had used so much space. In system information I had this view. Can anyone help me find where to clear this back up which is taking up so much of my hard drive.
MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.2)
