`adb backup`. All you have to do is turn on developer mode to enable adb, root is entirely unrequired. You might need to log into accounts again, I'm not sure.

Do note that this can take a while, depending on whether you back up your sdcard and how much storage is in use. You can choose to backup individual apps, or everything, to use encryption, etc. If you install TWRP recovery (root is only required for the installation, not the maintenance), you can do a full-phone backup.
