For .Mac subscribers: With Backup 1.2.2, the music you buy from the new iTunes Music Store can easily be copied to CD or DVD for safe storage thanks to the new QuickPick option. You’ll also find a handy QuickPick for backing up Safari settings, plus a QuickPicks customization feature that hides QuickPicks you don’t use.
Installing this version removed all the customised choices from the list of items to backup. It might be a good idea to take a screenshot of that list before installing. Now I have to go and find everything to add back to the list.
