If your Mac has the Drew image, do not use Migration Assistant or the Mac OXS Install DVD to restore your files from Time Machine. Saving system files in your Time Machine backup will cause conflicts with Drew networking software and prevent you from logging into your computer if you try to restore them. Use only the recommended settings listed below to configure back ups using Time Machine on your Drew-issued Mac. |

Using Time Machine for the First Time
...
Before you start using Time Machine, you will want to purchase an external hard drive on which you will be backing up all of your data. The larger the external hard drive, the better. 1 TB hard drives are quite affordable and will provide you with more than enough storage to back up your computer. For support regarding the use of external devices, please see the product documentation or contact the manufacturer.The first time you back up your computer, it can take quite some time, so be sure to give yourself plenty of time before starting your backup.
| Tip |
|---|
Time Machine preserves permissions in files. If you didn't have permission to read a file before backup (such as a document from another user account on the local machine), you won't be able to read it after the file has been backed up or once it is restored. |
Macs with the Drew Image: Exclude Items from Backup
| Warning |
|---|
Please If your computer has the Drew image on it, please use these recommended settings when configuring Time Machine in order to preserve your computer's ability to communicate with the Drew network. |
In the Time Machine panel of System Preferences, click on Options to choose things not to back up.
Click on the + sign to add items to the Exclude list.
Change the drop down menu at the top to Macintosh HD. You should see Applications, If you use Time Machine you should only back up the USERS section of your Drew Mac. This will contain any files such as documents, photos, videos, and music you've created and saved to your computer. When you select the option to exclude files, a window will appear asking which items you would like to exclude. While holding the "Command" key down, click every folder that isn't titled "Users". Once all the appropriate folders are selected, click "Exclude".
...
This will then prompt you to choose a location to back up your data. Select your external hard drive or flash drive and click the button that says Use Backup Disk. 
The first time you back up your computer, it can take quite some time, so be sure to give yourself plenty of time before starting your backup.
...
It may ask you to erase the disk in order to format it for storing Mac files. If it does, select Erase Disk only if you are positive that you don't need any of the files already on the external hard drive. 
Next it will begin partitioning the external hard drive and start a countdown until the back up will begin. 
Once it starts backing up your files, it will look like this:
A pop up may appear that looks like this and will give you an estimate of how much time is left on the back up:
Once it is complete, the pop up will disappear and you can close Time Machine.
Keep Installation Media for 3rd Party Software on Hand
- Time Machine will not save third party software applications (programs that let you do work on the computer, such as Pages, Google Chrome, or VLC. )
- This keeps the amount of data on the backup drive to a minimum and saves space, as well as taking less time to back up.
- You will need to re-install any software you purchased for the computer using the software manufacturer's web site or media you received after purchase.
- System files will be restored by a re-image and are therefore not at risk for being lost.
- Drew-supported applications can be downloaded again through Self Service or by having your Mac reimaged at the CNS Helpdesk.
