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 swap it with the offsite hard disk to keep all your vaults updated. To set up your Aperture backup system, you'll need to do the following: 1 Determine the number of vaults you need. For example, do you need one for routine backups, one for weekly backups, and one for offsite storage? 2 Determine the number of hard disks you need for routine backups. 3 Determine the number of hard disks you'll use for storing backups offsite. 4 Connect your hard disk drives to your computer. 5 Open Aperture and create the vaults you need, assigning a hard disk to each vault. 6 Update the new empty vaults with copies of the Aperture library. 7 Disconnect one of the vault hard disks and take it to an offsite location for safekeeping. 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 18 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. For step-by-step instructions for initially setting up your hard disks and backup system, see Appendix A, "Setting Up an Aperture System," on page 625. Working with the Vault Pane You use the Vault pane below the Projects inspector to set the location of your vaults and check their status. To show the Vault pane, do one of the following: m Choose Window > Show Vaults (or press Shift-R). m Click the Vault Pane button. 614 Part IV Distribution and Backup
