While technology is improving every day, it does fail sometimes. Frequently backing up essential data is extremely important. Please see the instructions below for your operating system and backup method.

Windows

Where is my data?

On a windows machine data specific to each user is stored in the User Profile. Typically every user has their own profile. In the Windows XP operating system user profiles are stored in the C:\Documents and Settings directory. In the Windows 7 operating system, your profile data is located in the c:\users\username directory. Inside this directory are all the files specific to you, including your Desktop, Favorites, My Documents, My Pictures, and My Music.

Macintosh - Backup

Where is My Data

On a Apple Macintosh computer running OS X data specific to each user is stored in their home directory. Typically every user has their own home directory that may be located by navigating to Macintosh HD / Users / username. Inside this directory are all the files specific to you, including Desktop, Documents, Movies, Music, Pictures and Library (a.k.a. settings).

Using a Hard Drive and Time Machine (Recommended)

Backing up with Time Machine is the easiest way to be able to backup and restore your Apple computer. To use Time Machine you must be running OS X 10.5 Leopard and have an extra blank hard drive - this can be internal or external to your computer. More information about Time Machine can be found at Apple's website If you need to be upgraded for Time Machine please contact Technology Services x6111.

Preparing Your Hard Drive

  1. Connect your extra hard drive. It should show up on the desktop.
  2. To gain the most performance you should format your hard drive with Disk Utility. Open Disk Utility by navigating to Macintosh HD / Applications / Utilites / Disk Utility
    1. Select your extra hard drive in the left hand column. Make sure you select the correct one!
    2. You may see two parts to your extra drive. Click the top most part.
    3. Click the Erase tab on the right.
    4. Volume format should be Mac OS Extended (Journaled).
    5. Name the hard drive something that differentiates it as a backup drive such as Backup_Drive.
    6. Click Erase.
    7. After a few moments the process will complete. Quit Disk Utility

Enabling Time Machine and Backing Up

  1. Navigate to Apple Menu / System Preferences / Time Machine.
    1. Click Change Disk and select your newly formatted backup drive.
    2. Click Options to exclude any folders. If your extra hard drive is large enough just backup the entire thing. This is most effective when recovered from a crash. Otherwise exclude folders you do not want.
  2. Turn on Time Machine by clicking the On switch.
  3. Backups will begin and be automatic as long as the hard drive is connected. You do not have to worry about scheduling. By default Time Machine will make incremental backups every hour, every week and every month. Let it do the math.
