Q: If my computer crashes, is a backup service online restore my iTunes music well
A: If you set your computer to back up your iTunes music, you'll get your music library back when you restore your data. You just need to make sure you back up your music files when you set up the online backup configuration. Most online backup services have some sort of program that automatically selects the critical data backup, but you should always double check to make sure it is what you want recorded capture.
We really like Carbonite and Mozy as online backup services, and support both PC and Mac. You can also check our online backup critical to choose one that is best for your situation.
