Currently Being ModeratedNov 13, 2010 2:09 AM (in response to brlock)You can't change the iTunes behavior, as far as I can tell.
However, you can use a feature of NTFS to point that folder to another drive. This feature is typically called a "junction" or "symbolic link".
You can use this tool to create a junction:
Download the "junction.exe" file from the link above and place on d:\
For example, let's say you want your iPhone backup to be D:\backup. You would do this:
1. close iTunes
2. Move the folder content c:\documents and settings\user\application data\apple computer\mobile sync\backup to D:\backup
3. Open a command prompt (CMD) and enter these commands:
(FOR WINDOWS XP)
D:\>junction "C:\Documents and Settings\username\Application Data\Apple Computer\Mobile Sync\Backup" D:\backup -s
(FOR WINDOWS VISTA / 7)
D:\>junction "C:\Users\username\AppData\Roaming\Apple Computer\MobileSync\Backup" "D:\backup" -s
NOTE 1: Change "username" to match your current username, of course.
NOTE 2: You can change the target D:\ for any other drive you have, like a external drive.

Currently Being ModeratedDec 18, 2010 10:03 AM (in response to brlock)IT WORKS!!
Here is what I did:
1. Created on my E: drive the following folder: \iPod BUP\MobileSync\Backup
2. Moved the entire folder "c:\Users\MYUSERNAME\AppData\Roaming\Apple Computer\MobileSync\Backup" to the new folder "E:\iPod BUP\MobileSync\Backup". So that the original MobileSync folder was empty.
2. Downloaded the Junction program, installed it.
3. Used the command:
junction “C:\Users\asus\AppData\Roaming\Apple Computer\MobileSync\Backup” “E:\iPod BUP\MobileSync\Backup” -s
Re-Open iTunes and synced. No error. Sync and backup still functional.
This is a really great help if you have very large ipod/iphone backup and running out of space on your C: drive!

Currently Being ModeratedJan 19, 2011 3:40 PM (in response to sebmkd)I did this successfully with a win7 machine (with a small, ssd) to an external drive. Oddly, I found that it didn't work at first. I had to rename the external drive's letter to D (rather than Z) and then it worked.
Just make sure the rest of the junction syntax is correct - you can put the new backup folder where ever (I think) but make sure to name it correctly.iOS 4

@ramirovgonzalez & hizaira:
Once you transfer the files out of the original "Backup" folder (on your C: drive) rename or delete that "Backup" folder so that junction can create a new one which links to your target folder.

Didnt work. I followed the instructions plus I changed the name of the driver from d to f . The message on command prompt is " 'D:\' is not recognised as internal or external command, operatable program or batch file"

- Close iTunes
- Download junction.exe from Microsoft and in Windows 7, place it in the C:\Windows folder.
- Remove the folder "C:\Users\%USERNAME%\AppData\Roaming\Apple Computer\MobileSync" and all sub folders. (so there is no MobileSync folder anymore)
- Create a new forder structure on an other drive for example: "D:\Backup\MobileSync"
- In Windows 7, open a command promt as an administrator. Now execute the following line....
- junction.exe C:\Users\%USERNAME%\AppData\Roaming\AppleC~1\MobileSync "D:\Backup\MobileSync" -s
- The command will have created an folder (looking like a shortcut) in the origional location on the C:\ drive.
- Now connect your Apple device of choice and watch the folder "D:\Backup\MobileSync" get filled up with stuff.

Oops, sorry proohu01, I left out .exe from the command. The response I got from the cmd when typed in correct was a lot of information about what the different postfixes do (-q, -s), starting of with information about the creator and then following up with: The first usage is for displaying reparse point information, the second usage... (and so on)
Does this indicate that the junction worked? (I can't see any folder (looking like a shortcut) in the origional location on the C:\ drive (Roaming\Apple Computers\)
