What is Time Machine?

Time Machine is an application provided by Apple located on your Dock that is a useful backup service.  Read the following instructions carefully before attempting to configure or use Time Machine to back up your files.

...

If you are using a Time Capsule to back up your Drew-issued Mac, please carefully read the instructions for configuring Time Capsule using Drew network resources.

Using Time Machine for the First Time

Tip

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.

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.

Exclude Items from Backup

Warning

Please use these recommended settings when configuring Time Machine in order to preserve your computer's ability to communicate with the Drew network.

...

Once you've completed this process, you can use the Time Machine interface if you need to restore your files.

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.
