A couple of suggestions for future reference. If you are a Mac user (Apple), I would seriously suggest you purchase Time Machine and have it running at all times. It performs continuous back-ups of your critical data (or your entire hard drive image) at intervals you configure. If you ever have a problem with your device, you can restore based on the last backup image.
I have a wireless version which I find very effective.
As for bookmarks, there is an excellent FREE open source tool called Xmarks (I believe they were just acquired so it may have changed names). it will synchronize all of your bookmarks across every device you own (Mac, PC, iPhone, iPad) and updates/synchronizes every time that you make a change on one machine (i.e. add bookmark, delete, edit...etc.).
You can find the product here:
