What is backup error (-43) when trying to update an iPod touch?

Try moving the existing backup file to a safe location so iTunes has to create an entire new one. The file is located here:

The folder where your backup data is stored changes depending on the computer's operating system. Since iTunes only keeps one backup per device, you should ensure the backup folder is included in your periodic data backup routine.

iTunes places the backup files in the following places:

• Mac: ~/Library/Application Support/MobileSync/Backup/
• Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
• Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\

Note: If you do not see the AppData or Application Data folders, you may need to show hidden files (Windows XP, Windows Vista and Windows 7), or iTunes may not be installed in the default location. Show hidden files and then search the hard drive for the Backup directory.

I have the same problem, but i don't understand what you mean? Where should i move the file and how do i know that it is a "safe place"?

Hey!!

After many failed attempts this is what worked for me:

Step 1. Right click on your phone in the left hand side bar and select Back Up

Step 2. Restore your phone and use the option where you restore and update

Step 3. When its done it will ask you to use the back up you previously completed

Hopefully this works for you!!!

Thanx I got my iPod updated safely!! ^-^

This worked perfectly thank you so much!! ^-^
