Hi I'm new here I've been interested in Linux and tested out a few flavours over the last year

I'm currently thinking of getting a tablet and installing Linux Zorin OS 6.1 lite

on it so it could dual boot it with the android OS.

If you could let me know how to
1/ back up the tablet
2/ Root the tablet
3/ install Linux Zorin as a dual boot properly on the tablet
it would be most appreciated.

My storage plan is
Android: 8 GB internal memory
Linux: 32 GB SD card.
