Automatically back up files at import
Creating copies of your photos from the moment you take them is essential to the preservation of your work. In Aperture, you can back up your original files as they are imported, using the Back Up Files import option. Backing up your image, video, and audio files at import ensures that if something catastrophic happens to your computer system, copies of your original files are stored somewhere safe. If you back up your files during import, Aperture makes a copy of each file and places the copied files in the location you specify.
Back up your original files during import
In the Import browser, choose Backup Location from the Import Settings pop-up menu.
The Backup Location controls appear in the Import browser.
Do one of the following:
To back up your files to the Documents folder: Choose Documents from the Backup To pop-up menu.
To back up your files to a new location: Choose “Choose” from the Backup To pop-up menu, then select a location from the dialog that appears.
Note: It’s a good idea to back up your original files to a location other than your computer. This is the only way to ensure that your original files are safe if something catastrophic happens to your computer.
Turn off automatic backup during import
Choose None from the Backup To pop-up menu.
