Hello there,
I don't know what phone you're using. If you have a Samsung, the newest phones works with Samsung switch. It works very easy. Just connect your phone with your computer and open switch. Then unlock your phone screen and a menu appear. Just hit the backup button and it starts. If you're on a older phone, use Samsung kies.
If you have another smartphone :every phone comes with his own backup software so go check online eventually if you find something.
If you can add a external SD card inside your phone, there are a few tools in Google store to simply backup software and sms, pics etc... to your external SD card. Hope this works for you!
