Before you install a new version of any software you've been using, it's always a good idea to back everything up.

This means pictures, video, music, and text, but it also means project-specific files, which vary depending on the application.  The idea is that, if anything goes wrong, you could feasibly resort back to the previous version of your software without losing any data.  It's best to use an external drive, or an internal drive that is separate from your main one.  Don't rely on the new install to leave your old project files alone.  If something goes wrong, that could be irreversible.

For example, installing the new iPhoto will erase old iPhoto files stored in the trash.  Some people store files in the Trash as a sort of intermediary, thinking they might restore the files later. Make sure everything you are considering keeping is somewhere safe!

The best way to do a safe backup is through Apple's Time Machine.  This method is automatic and comprehensive.  First, make sure the drive you're backing up to has enough space.  Then activate Time Machine by going into System Preferences, clicking the Time Machine icon, and selecting your Back Up Drive.  You can custom select which types of files you want to back up if you need to.

Do this before any major change takes place on your computer.  We don't want you to lose all your hard work!
