I don't understand what in the universe is Time Machine backing up! My MBA is only 256GB. The first backup was about 75GB which was very close to the size of the used space on the hard drive. I typed and saved a few documents and installed some very small apps. The backup size increased to 77GB. To me that was too big of an increase but I was oK with it. Then the backup size kept getting larger and larger although I was not installing anything and not saving anything. I was using the MBA only to surf the internet and watch streaming movies and streaming TV. I was not downloading anything!! Now the backup is 176GB and each back up says something like "backing up 50GB". Backing up what???? How is it that my available storage in About This Mac is 166GB of 245GB (245-166 =79) but my Time Machine backup is 176Gb? I could understand if I had downloaded some huge files and then later deleted them. Then maybe Time Machine is backing up what I deleted. However, as I said, I haven't downloaded nor saved anything!! I am tempted to dump Time Machine and try Carbon Copy Clone!!
