Time Machine is the easiest way to back up and restore your Mac. In this guide you will learn to use Time Machine to go back in time and recover changes you made to apps, documents, photos and etc. Most Mac users do not know the life saving power and potential of this killer app, as this is the easiest way to backup and restore your Mac .
First you will need:
- A Mac running Mac OS X v10.5 Leopard, v10.6 Snow Leopard or Apple’s upcoming Mac OS X 10.7 Lion. (You can find what version of Mac OS X you are running by clicking the Apple menu at the top lefthand corner of the screen and choosing “About this Mac”)
- A USB external hard drive that is greater than 250 GB – if you need help finding one we can help you purchase one and answer any questions on finding the perfect match for your Mac.
Backing up:
- Plug your external hard drive into your Mac
- Your Mac will then prompt you with:

If you do not see this window, check to see if your external hard drive is turned on and plugged in correctly
- Click ”Use as Backup disk”
That’s all you have to do for Time Machine to automatically back up your data and apps. As long as your hard drive is plugged in; Time Machine will create hourly backups for the past 24 hours, daily backups for the past month, and weekly backups until your backup drive is full. Keep in mind that the first time you run your Time Machine backup it may take several hours for it to complete, however you can still use your Mac while it transfers your data.
Restoring files from Time Machine backups:
Time Machine allows you to go “back in time” to restore files, versions of files, or your entire Mac OS X system. Make sure your backup disk is connected to your Mac (if not, Time Machine will alert you that “The storage location for Time Machine backups can’t be found” when you launch Time Machine).Restoring specific files or foldersWhile your backup disk is connected, click the Time Machine icon in the Dock and the Time Machine restore interface appears.

You can select the date from which the backups were made on the bottom right hand side with the 3d arrows and preview files by tapping the spacebar to activate Quick look.
Restoring your entire system from a backup:
With your backup disk connected, start up your Mac from your Mac OS X v10.5 Leopard or Mac OS X v10.6 Snow Leopard installation disk. After starting up, use the Restore System from Backup feature of the Mac OS X Installer DVD.
Restoring a Time Machine backup on a new Mac:
When you buy a new Mac, you can transfer all of your applications, files, settings, and other information from a Time Machine backup you’ve already made. You will be asked if you want to transfer files when you start up your new Mac for the first time. Or, you can use the Migration Assistant (located in Applications/Utilities folder on your Macintosh HD).
