Yes, I did read the instruciton and I don't see a way to tell where to save my backups to that's why I'm asking the question.
The article tells you where the backup will be saved. There is no setting to change it.
"On a Mac: ~/Library/Application Support/MobileSync/Backup/
On Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
On Windows Vista: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\"
It's kinda dumb for iTune to not offer me an option to where I want to save my backup to. Let's say that it's saved in my "C" drive. If my computer is dead where can I restore my backup from then.
You restore your "C" drive from its backup. Then you can restore the iPhone. Why are you so concerned about the iPhone backup when your "C" drive is gone? It's unlikely that the iPhone will need restoring at just that time. You should be more concerned about always having a good backup of your "C" drive.
In addition, what about all my imported musics? Is there a way to specify where the imported music can be saved to? If the default is "C" drive and no option to specify a location that I want, I think it's pretty dumb.
The music is not saved in the iPhone backup files. Any music on the iPhone is already in the iTunes music library on your computer (music purchased using the iPhone will be copied to the iTunes library when syncing), so doesn't needs to be in the iPhone backups. The iTunes music library (probably on your "C" drive, but can be set elsewhere via iTunes preferences) will be backed up during your normal backups of the computer hard drive(s).
