What is to do for non-Google service user? Thanks

You have an android phone, it’s google based, why would you not be a google user?

There are lots of android backup apps free out there. Some for specific purposes like backing up your text messages and others for an all-in-one backup. Easy Backup & Restore is a free app that lets you back up your contacts, call logs, text messages, calendars and bookmarks.

PS: Google is more than willing to help keep all your apps and data safe. If you go into your phone's settings, you'll find a section called Backup & Reset. In here you'll find an option for backing up your data, including Wi-Fi passwords, preferences and app data. All of this will be tied to your Google account, which you can set to automatically restore when you re-install an app.
