I have an iPhone 5. I made a backup copy last week with my iTunes. I discovered that I had erased some notes so I wanted to restore the backup from iTunes. When I plugged the phone to the PC, iTunes asked me to update the iOS software in order to proceed with the restore process. I did the update but also a new backup over the old one was made.
When I look for the backups available to restore it only shows the one from yesterday but not the one from last week. Is it possible to recover older backups from iTunes even if they have been overwritten by the latest backups?
