Lesson: Create a Time Machine backup server
In this lesson, you’ll learn how to:
Add additional storage for Time Machine service
Configure a Time Machine server to use your additional storage
Configure your client machines to back up to the Time Machine server
Step 1. Plug the USB disk into the server
Use Disk Utility to format the USB hard disk for use with a Mac (“OS X Extended (Journaled)”), if needed.
Although USB disks are the most common external disks, you can use any other external disk that can connect to your server, like FireWire or Thunderbolt disks.
Step 2. Set up Time Machine service
Open the Server app to see the list of services available in OS X Server. Select Time Machine, then click the Add button to add a destination.
Select the USB disk, then create a new folder on it called “Storage.” Click Choose.
Step 3. Turn on the service
Click the button to turn on Time Machine service.
Step 4. Set up Time Machine preferences on the client
On the client Mac, choose Apple menu > System Preferences, then click Time Machine. Click Select Disk, then choose Storage in the list of available disks. Click Use Disk, then turn on Time Machine.
Step 5. Test your configuration
After the client Mac completes its first backup, you can check the server and make sure everything is working as expected.
Open the Server app, click Time Machine, then click Backups. You should see the name of the client Mac on the list.
You’ve learned how to set up a Time Machine server to keep the backups for clients on your network.
