How Do I Make Backup Copies?

How do I make or save a backup copy of an iPhoto Book project onto an external hard drive? Do I have to save the entire iPhoto Library? How? Drag & drop -from iPhoto to Finder- doesn't appear to work (for either the Library or the Book). There are no "Save As" options anywhere in iPhoto. "Export" ain't it either.

Welcome to the Apple Discussions. You can make a backup of just your book but that requires you duplicating your current iPhoto Library folder, opening it with iPhoto (launch with the Option key depressed) and then delete all the photos but those in the book and any that you might want to put in the book. Then save that iPhoto Library book folder to a CD.
I create a new library for each book I create and then move photos from my primary library to the book library with iPhoto Library Manager. Saving that folder after ordering a book assures me I can reorder a duplicate copy at anytime in the future. I just copy that folder back to the desktop, open it with iPhoto and order.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
