iTunes local backup password
I lost my iPad mini's local backup. I tried all combo possible to no avail. I deleted from the list of local backup in Device preference already. Yet it still ask me for a password. How do I change/delete the current password. Right now, the local backup is no good as I had deleted it. I like to start a new backup with a new password. I do not want to wipe my iPad though. iOS version and iTunes version is up to date.
