New iOS 7 versions (such as iOS 7.1.2) can help users fix bugs and have better experience with iPhone. Yet, any iOS update (including iOS 8 update ) may cause data loss, such as you lost contacts, photos, messages,notes and call history. Many users have lost iPhone data after iOS 7 upgrade. If you don't want anything missing, you'd better backup iPhone data before updating to iOS 7 (including iOS 7.1, iOS 7.1.1, iOS 7.1.2, and this also applies to iOS 8 update).
It is easy to backup iPhone data before iOS 7 update. You just need to download and install the professional iPhone backup tool, iPhone 5 Transfer, on your Windows computer. It will backup all iPhone data, including photos, movies, music, playlists, contacts, messages (iMessages, MMS, SMS, WhatsApp, Tango), apps, etc.

Here are the details of the guides on how to backup iPhone.
iPhone 5 Transfer allows you to backup iPhone data onto computer before iOS 8 upgrade in both readable formats and unreadable formats.
Readable formats: All the backed-up files will be saved in formats that you can access directly, such as text contents are saved in .txt, .xls, .xml, contacts can also be in vCard/VCF files, and media like songs, videos in their original formats. This can help you access your files at any time.
Unreadable formats: All the backed-up files will be saved as SQLITE Database, which is the iTunes bakcup formats. This will help to prevent someone from viewing your personal data without permission, and you can easily restore from this backup.
Connect iPhone to computer and run iPhone 5 Transfer.
