It is possible to do an iPhone backup by using iTunes on Windows or Mac computers (in most recent versions of Mac OS, this feature is included in Finder).
To do that:
* Make sure iTunes is installed.
* Connect your iPhone to your computer using a Lightning/USB cable.
* Open the device in iTunes (or Finder on Mac OS).
* If you want to have a more accurate detection, ensure that the encrypted backup option is activated and choose a secure password for the backup.
* Start the backup and wait for it to finish (this may take up to 30 minutes).
* Once the backup is done, find its location and copy it to a place where it can be analyzed by `mvt`. On Windows, the backup can be stored either in `%USERPROFILE%\Apple\MobileSync\` or `%USERPROFILE%\AppData\Roaming\Apple Computer\MobileSync\`. On Mac OS, the backup is stored in `~/Library/Application Support/MobileSync/`.
