Change iPhone/iPod iTunes Backup Directory from default C Drive

If you have portable external storage (1TB) or plus, why would you waste precious C (OS Partition) space with backups etc. Apple thinks that we shouldn't be allowed to change the backup directory.. Dunno why?? if you can change the directory where all music etc is stored, why not the backups.. There is a quick and easy way to do this though. Esp with Win Vista, Win 7. All you need to do is create a SYMLINK for the backup directory using standard MS utility "MKLINK". Below are the steps.

1. Make sure iTunes us not running.
   
2. You will need ADMINISTRATOR access to your computer. Open START and in the search type CMD. Right Click on the CMD.EXE and click "Run as administrator"
3. You will see the command prompt pop up. Change the directory to the iTunes Backup Directory which on WINDOWS 7 is "C:\Users\\AppData\Roaming\Apple Computer\MobileSync"
4. Cut the entire backup directory and paste it on your portable external drive. Say "H:\iPhone\backup". Make sure that there are no spaces etc in the new directory name on the portable drive.
   
5. After the cut/paste is complete, in the Command Prompt Window, type the following command "mklink /D backup H:\iPhone\backup"
6. This will create a symlink called backup in the iTunes backup directory pointing to your portable drive directory.
7. Open iTunes and connect your iPhone or iPod Touch and perform a backup. All the data will be stored on the portable drive from now on. You can still click on the backup SYMLINK created on your C drive to access the backup.
