Planning Your Backup System

As you begin working with Aperture, it’s important to perform regular backups of your images. When you import new images from your camera, you should immediately create a backup so that you have copies safely stored. As you routinely work with Aperture, creating new image versions and making adjustments, you’ll want to make sure your work is copied to disk and your backup vaults are up to date.

A typical backup system used with Aperture might look like the following:

This system backs up the Aperture library to two vaults stored on external hard disks. You routinely back up the library on one external hard disk. You use the second hard disk as a backup that you keep offsite. You can then alternately back up the library on your onsite external hard disk and rotate it with the offsite hard disk to keep all your vaults updated.

To set up your Aperture backup system, you need to do the following:

When planning the amount of storage space you’ll need, estimate the amount of disk space needed to hold your existing digital images (photos you plan to import into Aperture) and the amount of space you might need for new projects. For example, RAW images typically require 8 to 25 or more megabytes (MB) of disk space per file. Estimating the number of images in a typical project and the number of projects you usually do in a year, you can make a rough estimate of what might represent a year’s storage space.
