Some of the most important data you have are the contacts in your address book. Plus, trying to re-enter all that data if it is lost is a complete pain. Here is the easy and simple ways to backup this information and restore it if it becomes lost.
OS X has a ton of backup tools and methods. However, if you are going to backup one thing manually, I would suggest saving your address book to a separate file. The file will be small and portable.
Go ahead and back it up right now. Email it to your work or to a gmail account for save keeping.
