If you’ve ever worked on a computer of any sort and lost data you spent a great deal of time creating, you’d know how important it is to take backups. While some people’s data is more important than others, it’s great practice for all of us to get in the habit of backing up or data. With Mac, you don’t even have it manually do that anymore. The Time Machine features allows us to set backup times such as hourly, daily, weekly and whatever option you prefer.
Apple’s ultra-handy backup utility for Mac OS X operating systems is Time Machine. Today, I’ll show you how to easily set up Time Machine on OS X so you can store data.
