Backing Up iTunes 11 Library All the articles I've read suggest that the correct technique to make a local backup of my iTunes 11 library is to:


Connect the pertinent device (iPod)
Go to the Summary Tab
Click "Backup Now" and follow the instructions.


Problem is there is no "Backup" feature of any kind offered anywhere in the Summary Tab or anywhere else in iTunes that I could find. Has anyone else noticed this?
It sounds like you have gotten a little confused with the difference between backing up your iPod and backing up your iTunes library. You can back up your iPod to iTunes on your computer, but this is different than backing up your iTunes library itself - all the music, movies, books, apps, and such that you have placed in iTunes. 

If you want to backup your iTunes library
(Apple.com):


Open iTunes Preferences.

Mac: Choose iTunes > Preferences.
Windows: Choose Edit > Preferences.

Click Advanced.
Make sure the option to "Copy files to iTunes Media folder when adding to library" is selected.
Choose File > Library > Organize Library.
Select the option to "Consolidate files."
Locate your iTunes library. 

If you can't find it, open your iTunes Preferences and click "Advanced." The location of your iTunes folder will be listed in the "iTunes Media folder location" box.

Copy the iTunes library directory over to your backup location. 




If you really would like to back up your iPod:


Plug your iPod in and view its details.
Under "Summary" tab there is a heading called "Manually Backup and Restore"
Select "Back Up Now" from under that heading.
