Change backup location?

My C-drive is full(has 3gb free) and itunes fails to backup my ipad (32gb) when trying to install the new iOS. OTA updates keeps on failing aswell.


How do you change the default backup location of your ipad?

iPad, iOS 5.1.1, Trying to get to iOS 6

What is the current format of the C: and D: drives? Reformatting destroys any data currently on the drive so you would need to backup that data first, then restore it afterwards. assuming it is necessary. NTFS should be the default format for any reasonably recent Windows computer. How much free space is there on C:? How big are the device backups? My understanding is that the first step when you try to restore a device is that the existing backup is duplicated. If there isn't enough room for that operation the restore fails, but iTunes may not clean up the duplicate data it has started creating.

For the relocation to work properly the Backup folder inside %AppData%\MobileSync should be moved to drive D:\ for example into a new folder called D:\MobileSync, leaving %AppData%\MobileSync empty and more space on the C: drive than there was before. %AppData% should resolve to C:\Users\<User>\AppData\Roaming.


If you moved the backup data as described then the following command would relink the data folder to path that iTunes is expecting.

MkLink /J "%AppData%\Apple Computer\MobileSync\Backup" "D:\MobileSync\Backup"


After issuing the command the data would appear to be exactly where it was before, but the space is only taken up on D:, not on C:. When iTunes is run the existing set of previous backups should show under Edit > Preferences > Devices.
