• An IBG computer account
• A Mac desktop or laptop
• On the CU wired or wireless network or connected by CU's VPN

If the computer is in the IBG or RL4 building and is connected by an ethernet wire, then starting backups is easy.

1. Go to “System Preferences”
2. Launch the “Time Machine” control panel
3. Click on “Select Backup Disk…”
4. Select Time Machine on “linux” and click “Use Disk” Sometimes this doesn't work the first time. If it gives an error, just select it and try again.
5. Enter your IBG username and password into the login box and click “Connect” This will be your identikey username, but may be a different password than your identikey password and the password for the local computer

Your Mac will do a full backup, and then do an hourly backup of files that have changed.

These steps apply for any computer connected to “UCB Wireless”, “eduroam”, or using a wired connection from outside the IBG subnet, such as from the ARC building or Muenzinger. This can also work from off campus, if the CU VPN is running.

1. Launch “Finder” (the smiling blue icon)
2. Press “⌘K” or select the “Go” menu and “Connect to Server… ⌘K”
3. Into the “Server Address:” field, type

   afp://linux.colorado.edu

   and press “Connect”

4. Enter your IBG username and password into the login box and click “Connect” This will be your identikey username, but may be a different password than your identikey password and the password for the local computer
5. Go to “System Preferences”
6. Launch the “Time Machine” control panel
7. Click on “Select Backup Disk…”
8. Select Time Machine on “linux.colorado.edu” and click “Use Disk” Sometimes this doesn't work the first time. If it gives an error, just select it and try again.
9. Enter your IBG username and password into the login box and click “Connect” This will be your identikey username, but may be a different password than your identikey password and the password for the local computer

By default Apple Time Machine backs up the entire computer. This is generally useful as it is possible to completely reinstall a new computer to the state of the backed up computer using Time Machine. This will recover all applications, settings, and files.

You may have files on your computer which you do not want to backup because they are personal files inappropriate for a work backup, or are simply large scratch files which do not require a backup. Excluding folders from backup is easy.

1. Go to “System Preferences”
2. Launch the “Time Machine” control panel
3. Click “Options…”
4. Click “+”
5. Choose the files or folders you do not want backed up, and click “Exclude”
6. Repeat as necessary to exclude all undesired items.

Laptops which are frequently connected to non-CU networks, such as your home network, may complain that they cannot find the Time Machine backup destination. The software at http://www.klieme.com/TimeMachineScheduler.html works around this problem by enabling Time Machine only when your computer is on a designated wireless network.

1. Download Time Machine Scheduler 4.0 Beta from http://www.klieme.com/TimeMachineScheduler.html (direct download link)
2. Install the software
3. Run Time Machine Scheduler from the Applications folder
4. Click the “Advanced” button
5. Unlock using the padlock icon
6. Under “Network Connection” choose “Wi-Fi”
7. Under “SSID” enter “UCB Wireless” or “eduroam” depending on which wireless you usually connect to

This will limit Time Machine to only run when the laptop is on the CU wireless network. Time Machine will show that it is turned off, because the Time Machine Scheduler application is controlling when it runs.

1. Click on the Time Machine icon on the menu bar
2. Click “Enter Time Machine”
3. Navigate to the date and files you wish to restore
4. Select the files or folders, and click “Restore”
