You can use a backup to restore this information back to your device after a software restore or update, or to transfer information to a different device. For more information about creating a backup and restoring from it, please read:

Use iTunes to restore your iOS device to factory settings

Back up and restore your iPhone, iPad, or iPod touch using iCloud or iTunes

•macOS: ~/Library/Application Support/MobileSync/Backup/

•Windows 7, Windows 8, Windows 8.1, and Windows 10: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\

If you run EPV on the computer where iTunes is installed, it will allow you to browse through all backups stored there.

If you want to encrypt the information stored on your computer when iTunes makes a backup, select Encrypt iPhone backup in the iTunes Summary screen. Encrypted backups are indicated by a padlock icon, and a password is required to restore the information to iPhone. If you forget the password you can continue to do backups and use the device, however you will not be able to restore the encrypted backup to any device without the password. You do not need to enter the password for your backup each time you back up or sync.
