I had to restore my cell phone's address book from a backup a little while ago. Fortunately, I had a current one I could use. Otherwise, you'd all have heard the shriek, regardless of which time zone you're currently in. I've been compiling my address book since I got my first PDA in 2001, and i have been migrating it to new devices as i upgrade. Losing that data would be too brutal to contemplate, so I'm paranoid about backing it up. File this event under, "Sometimes, paranoia pays off."
