I have a 256 GB SSD installed in my Macbook Pro. Today I observed that Finder tells me that I have a free disk space of 247.51 GB, which is unquestionably wrong.
At the same time, in System → About this Mac, I can see I have 44.73 GB of available disk space. I think this number is more accurate, but it tells me that 202.78 GB of used space is backup, which is not right. I do not know the actual size of backup files, but my personal files take about 125 GB, so there cannot be 200+ GB of backup files.
I'm confused. What's happening to my computer?
Edit: This is the related snapshot, the size given by Mavericks are slightly different then yesterday, but it's still not making sense. I believe DaisyDisk's report is right.
The 256 GB SSD is the only hard drive that I have installed. I replaced the original HDD with it.
Edit 2: Today the available disk space gone crazy. It shows that I have 265.06 GB available...
