Upgrade Your Apple MacBook: Data Backup and Preservation.

Step 8 Be a Time Traveler.

One of the neatest things about the operating system you just installed is a new application called Time Machine. This continually takes snapshots of your computer's drive and saves them so that in case you ever have a problem and lose some data... you can simply look back in time. To do this you will need an external hard drive.

$99 500 Gig Drive

Once you have this drive the setup for Time Machine is very simple:

• Plug in your portable drive
• Select the drive in the pop-up window as your backup disk.
• If the window doesn't pop up, plug in your disk and click the clock on the upper bar near the wifi icon.
• Toggle the switch to on and it will start to back up your entire disk.
