Download TWRP (needs to be on your phone, this is for both KitKat and Lollipop)
Install Kernel Adiutor
1-Open Kernel Adiutor and tap the menu and scroll down to Backup
2-Just to be safe, make a backup of the stock recovery by tapping the (+), then Backup, then Recovery.
Give it a name (something like stockrecovery is fine) and hit OK.
3-Now tap the Flash IMG button and locate the TWRP file you downloaded.
Hit OK and choose Recovery. Confirm the next prompt (it should match the picture below) and let it install.

4-Reboot into recovery to make sure it installed correctly, and make a backup, by turning off the phone and holding Vol - + Power until 'Factory Reset Processing' appears on the screen and release. It is a little slow to load, so don't panic (it shouldn't take more than 3 minutes though).
Assuming it loaded you should have a screen with 8 buttons and some navigation buttons across the bottom.
5-Tap the Backup button to get to the configuration screen. Make sure System, Data, and Boot are selected. Below that window it shows where the backup will be stored and how much room is there. Tap it change to external storage if you want (odds are internal storage won't have enough room). I would also select Enable Compression to save some space on your card. Swipe across the bottom of the screen to start the back up. This usually takes 6-8 minutes on my phone.
6-When it's done, tap back then tap Reboot, then System to reboot normally.
IMPORTANT:
This will not save your user data stored on the internal storage!
This only saves the system, kernel, and internal app data!
