Backing up your iPhoto library

Backing up your iPhoto library
It's a good idea to routinely back up your iPhoto library in case image files become corrupted or unintentionally erased from your hard disk. The library is located in a folder named iPhoto Library in your Pictures folder on your computer.
To back up your iPhoto Library folder:

Copy the iPhoto Library folder on your hard disk to another disk. For example, you can copy your iPhoto Library folder to an external disk or burn a CD or DVD of your photos.
