I  have a MacBook with many photos.  The 500gb hard drive is filling up and the computer is running slow.  I am reading about referenced files, so I store photos in an external hard drive.  The problem is I loose the vault backup feature.  How do I back them up once they are on the external hd?  What do I do if the external hard drive goes bad?

    You need a second hard disk to back up the first.

    Thank you.


    OK, I will buy a second external hard drive.  Then, what is the best method to backup the first external hard drive?

    I include the drive with the referenced originals in my regular Time Machine backup of my whole system, so I do not have to worry about them. Also, all new original images are backed up right from the card, before they are imported into Aperture.

    I suggest buying drives in triplicate (yes, I do).  Use one drive for storage of your Referenced Originals.  Use the other two drives for back-up.  Rotate your back-ups regularly, store one off site, and never have all three drives in the same physical location.


    This has a higher initial cost than other strategies, but is, IME, the least costly to administer and the easiest way to secure my data.  Not having to worry about security is worth the initial cost, to me.


    I use SuperDuper! to copy/back-up/duplicate drives/drive contents.  Carbon Copy works well, too.
