Why do people use online storage to backup their files, folders, settings, etc. when they can just back them up on CD’s?

I tried running the BackUP and when I click ‘Back Up’, it does so over the Network without any problem to the chosen location, but when I set the schedule, nothing happens at all. The 2 PC’s are connected on a LAN in the same workgroup and I’ve tried it without passwords and it still doesn’t work. Any ideas out there in Computerland?

From what I understand, the iTunes backup feature only backs up your settings and maybe your documents, how can I create an image of my current ipad and back it up to that at a later date if I need to?

The last sync I did with iTunes and my iPhone deleted all my contacts. This actually happened twice, so the backup I had is gone. I do have my Contacts in my iPad, and would like to know if I can transfer them over to my iPhone through a sync. Thanks!
