I had a problem with the 3.2.2 upgrade which wound up requiring a restore. I ended up with missing books and music. I found two iPad backup file folders on my computer. Should only be one? I am concerned that future backup/restore operations may be messed up. I am considering: 1) uninstalling iTunes and all it's files from my computer, reinstalling, and doing a new backup. OR 2) Move the backup files to another folder and do a new backup. If it creates a new file, erase the old files. Any suggestions would be appreciated.
