Backing up iPhone on iTunes?

If I back up my iPhone on itunes on my computer, what gets backed up? Like does literally everything get backed up. Like photos, contacts, messages, notes etc? And where does it actually go? Does it create a folder on the computer or something?

Added (1). Is it only supposed to take like 1 minute?

By default, it back ups everything except apps I think. But, you can configure it and select what you want to back up. In windows, the backup location is documents\my music\itunes.

If you are backing up your iphone, ipod or ipad you need to be sure that the computer you are backing up on is the computer that you used to sync your device before. If it is the computer you have used before to sync then it will backup your apps, music and photos. I'm not really sure about contacts it may or may not back it up.

  • Restoring iPhone and backing it up? -Well my iPhone 4S has been going in and out of 3G to the no service circle a lot lately so I've read it's Apple recommended to restore your iPhone. -Now, my iPhone is backed up on my computer, but my question is, when I restore my iPhone back to factory default, am I still allowed to back it up after the restore so I don't lose all my contacts (300 contacts), pictures, etc. -Idk I'm a total noob when it comes to backup and restore for the iPhone: p.
