I've tried uninstalling and reinstalling iTunes but didn't seem to fix it. The process went very smooth, but same result. Right-clicking my iPhone on the left sidebar still doesn't give me the choice to manually Backup. After asking this question twice now over at the Apple Forums I've yet to recieve an answer. So I thought I'd come here for more hope. Any thoughts?
Extra details: iPhone 4 running 4.1.2, all 4 family members iPhone's seem to not be able to backup (meaning it's iTunes), Windows Vista 64-bit, iTunes 10.1.2.17

First off welcome to modmyi!
That's weird I never encountered a problem like that. Honestly if reinstalling iTunes doesnt work I don't know what will. Have you tried another comp?

Ohh yeah I forgot about that.
Ok to do that your going click the main windows icon to the left at the bottom/accessories/Notepad/file/open.../click on computer/Windows/system32/Drivers/Etc;
It might not show anything at first and if that happens then click the menu that says text documents to the right, and change to all files.
then click hosts and delete the last two lines that says gs.apple.
There should be 2 if there's more you can delete those as well.
Hope thus helps goodluck!

Hi. This worked for me after months of trying many different fixes. Give it a shot.
Locate the iTunesPrefs.xml on your PC. In Windows XP the iTunesPrefs.xml location is:
\Documents and Settings\username\Application Data\Apple Computer\iTunes
\Documents and Settings\username\Local Settings\Application Data\Apple Computer\iTunes.
With iTunes closed, I renamed this file from iTunesPrefs.xml to iTunesPrefs.xml.backup in both locations. Then I opened iTunes, connected my iPhone, and the backup was successful.
Note that doing this will force iTunes to recreate the iTunesPrefs.xml file with all it's default settings. Any user preferences you may have set within iTunes will be removed. You will need to set any user defined preferences again.
Let me know if this works for you.

Correct. Renaming to iTunesPrefs.xml.backup will remove the original file. Open iTunes, connect your iPhone and see if you can now Backup. If not, the point of renaming to iTunesPrefs.xml.backup was so that you could revert the original file back if this didn't work for you.
Did you open iTunes again to see if you can Backup again? Right-clicking your iPhone on the left sidebar should now give you the choice to manually Backup also.
Let me know.

If it created a new iTunesPrefs.xml replacing the file you renamed then it has definitely created a new one and it would have all iTunes defaults.
Are you sure you don't have iTunesPrefs.xml in another location also? Did you do a search?
Did you use a software utility named Backoff at anypoint to keep iTunes from always wanting to Backup your iPhone when it sync'd? If so, are there any other versions of iTunesPrefs.xml in the folder where you found it? Anything like a iTunesPrefs.xml.backoff?

When you connected your iPhone again did you attempt to right click on the iphone and select to Backup? With a new iTunesPrefs.xml file I'd expect you'd have these options again.
Okay then I think we've exhausted this option for you. Sorry it wasn't the solution. It definitely worked for me and my symptoms were exactly as you described. Good luck and let us know when you find the solution.
Oh, and you might want to try the same experiment with the iPodDevices.xml file you mentioned. Try renaming it and then opening iTunes again to re-test. If it doesn't work then you can always rename the file back to it's original name.

It's called editing the host file and it's used most when iTunes doesn't let you restore, I'm not sure how that plays into your problem but it's worth a try.
Sorry for not explaining earlier i tend to get ahead of myself.

Although replacing my prefs file adds the backup option (thanks), it also kills all my library settings (songs, ratings, etc.).
Is there no way to get the back up option to appear without losing all of my data?
