My rig has a dual HD setup: SSD + HDD.
I use my SSD for all of my storage access intensive purposes: IDEs, VMs, build cache, etc. So naturally I wanna move all other storage tasks to my HDD disc.

Lately I've found that around 7GB of SSD space is dedicated to iPhone backups. This is a waste of space - I almost never restore my phones and I don't really care for the time it takes when I do.

This is how you move the backup folder to a new location:


  1. Move the entire %AppData%\Apple Computer\MobileSync\Backup folder (including the root Backup folder) to a new existing location. In my case D:\Backup\iTunes Backup.
  2. Open a command line as an administrator.
  3. Make sure that %AppData%\Apple Computer\MobileSync\ is empty now and that the new location exists.
  4. Create a directory junction to that new location:
mklink /j "%AppData%\Apple Computer\MobileSync\Backup" "D:\Backup\iTunes Backup"
