Using Time Machine

Note: This section is only relevant if an encryption rule is configured for <Removables>.
If you want to use a new disk for a Time Machine backup and the operating system does not automatically suggest using it, use the following command in the Terminal application:

sudo tmutil setdestination -a "/Volumes/.sophos_safeguard_{DISK NAME}/"

If you use Time Machine with an encrypted folder, no old versions are displayed. However, the backups are stored in a hidden location. You are not able to read the contents of the files located in the hidden path. The backups contain only encrypted data and your contents are kept secure. To restore files, proceed as follows:

  1. Open Time Machine (for example by typing "Time Machine" in the Spotlight search).
    The content of your root folder is displayed.
  2. Press Shift - Command - G (for "Go to the folder:") and enter the hidden path of the encrypted folder you want to restore.
    If the encrypted folder you usually work with is named /Users/admin/Documents, then enter /Users/admin/.sophos_safeguard_Documents/.
  3. Browse to the file you want to restore, click the wheel icon from the Time Machine menu bar and select Restore <file name> to....
After returning from Time Machine to your desktop, your file will be restored and can be decrypted.
Note: The first Time Machine backup after a new installation of SafeGuard File Encryption takes longer and requires more disk space than usual. This is because OS X does not allow stacked files systems and thus all local directories for which secure mount points have been created (Documents, Music, Movies, etc.), the contents will be duplicated on the backup disk. However, after the first backup in the hidden location is complete, older backups are deleted and disk space is freed up again.
