What is actually backing up to iCloud?

[tootall]

I don't understand what is actually going to iCloud when I backup; the backup sizes are so different from one iOS device to another:

iPhone 4 32 gig = backup size about 300 meg
iPod 3gen 32 gig = backup size about 200 meg
iPad2 64 gig = backup size about 11 gig!!! and incomplete (as if it would require more space)


Why is the backup on the iPad2 so much bigger? all my iOS devices are about more than half full... so the sizes of the backups are really disproportionate, why?

Settings/iCloud/Storage and Backup/Manage Storage

This shows you whats backed up. You can click on your device name to see exactly what apps are backing up.

Thanks but when I go in preferences/iCloud/Manage/Backup/device name, I don't see any detail even if I double click on the device

I think it will only work once the bakcup is complete
