Configuring Data Backup in Mac OSX

Backing up your personal data is essential to prevent the loss of important documents and irreplaceable pictures. Time Machine is the built-in backup application for Macs that works with an external hard drive or Airport Time Capsule. The application automatically backs up the entire Mac, including system files, applications, accounts, preferences, emails, pictures, videos, and documents. It also remembers how your Mac looked on a particular day, so you can go back and view it as it was previously. If you keep your external drive connected at all times, Time Machine will backup hourly for 24 hours, daily for a month, and weekly until the drive is full.

Locating the Amount of Data

1. Open Finder and, in finder, open up the Macintosh Hard Drive.

2. In the Macintosh Hard Drive, find the Users folder and right click on it and click Get Info.
