Fresh System Restore with Déjà Dup


  1. First, get your system to a “fresh” state. Maybe it’s a fresh install, maybe it’s a new account on an old computer. Don’t worry about getting comfortable and customizing settings yet. Wait until after you restore your previous settings to change anything, as any customizations you make now may get overridden once you restore.
  2. Next, you need to install Déjà Dup.


  1. Open the Déjà Dup Backups application.
  2. Click on the big “Restore from a Previous Backup” button.
  3. A dialog will appear asking where your backup files are stored (your “Backup location”). Click “Search”.
  4. You will have to wait a big while the storage location is scanned. Once it finishes, select all the files you want to restore.
  5. Click the “Restore” button on the bottom left.
  6. Choose where to restore. Since this is a full system backup, leave it as the default (to restore over your current install). Click “Restore”.
  7. Wait. This can take a while.
  8. Reinstall any programs that you enjoyed in your previous install.
  9. Enjoy!


Permission Denied Errors

Some versions of Déjà Dup will not correctly restore files stored in a folder that you did not have write access to when you backed them up. After the restore completes, you will get an error screen listing each file that was not restored. You can still manually copy the files to where you’d like them to be by going to the temporary folder named in the error dialog and moving the files.

General Fallback

If for whatever reason, you have a problem after trying to restore with the “Restore files to original locations” option, try restoring again to a temporary directory and moving your files to where they belong.
