Partition Backups?

I know that without root and therefore being unable to "write back" the partitions, the following may be useless, but I wanted to ask nevertheless: does anyone have any idea which partitions to backup (and how, if even possible without root), so that we have a ready backup to restore (assuming we find a way to gain root/TWRP)?

Without root on the MDZ-19-AA, I cannot seem to see /dev/block...
