Time Machine Backup Disk Encryption

Time Machine Backups contain a working image of your computer at the time the backup was taken. For this reason, encrypting these backups is important.

First-Time Setup

If you are not currently backing up the machine, follow the Apple provided instructions for setting up encrypted Time Machine backups to an external disk.

Capturing Status

Per the Sparkbox security policy, we regulary capture and record employees' status for each security policy item.

  1. Choose Apple menu > System Preferences, then click Time Machine.
  2. Click Select Disk or Add or Remove Backup Disk (if you have multiple backup disks).
  3. Capture a screen shot which includes the status of all Backup Disks.

Your disk should show Encrypted under the name and after the disk size. If not, follow the instructions provided below.
