Samsung users can also back up data using Samsung Smart Switch to your computer. Smart Switch helps to move data across different Android devices i.e moving Samsung Galaxy S8 Plus backup data to Samsung Galaxy S9.

If you already have a custom recovery (TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and Nougat.
