I've learned from a friend tha OS 10 backs up regularly to your internal hard drive. The rationale is that it's another safety net, even if not one against your hard drive going bad.


My internal hard drive holds 320 GB. At the moment I have 112 GB of back ups on my disc. Only yesterday, the number was under 88 GB.


Something seems out of control. There's no way I've needed an additional 24 GB of back ups since yesterday. Is this normal? Can I turn off, or at least limit, the backing up that's taking place?
