Aperture: backing up referenced originals

Similarly, I have my Aperture Library on my internal drive and referenced originals on a 2TB external drive.

- Time Machine backs up the internal drive
 - SuperDuper backs up the external drive to 2nd 2TB external drive

I periodically update an Aperture vault that lives on the external drive, it automatically gets copied to the 2nd external drive by SuperDuper.

Side benefit: rotating offsite the 2nd external with a 3rd external gives an extra level of disaster recovery since it contains the Aperture vault and referenced originals.
