Narrative: Prior to taxiing onto Runway XX/XY at ZZZ I observed the pattern and both approach ends for landing or departing aircraft. None in sight; I radioed back taxiing Runway XY for departure. Approximately 500 ft from the threshold of Runway XY; I noticed Aircraft Y banking hard onto the final of Runway XY about 45 degrees to the left of my nose. The pilot appeared to have entered on a right base in what is otherwise a left traffic pattern. I called again stating back taxiing XY; assuming they would hear and also see me during their base turn. No response and they were lined up for XY head-on with me at this point so I applied 70% power to accelerate to a turn out at the threshold area. Aircraft Y proceeded to land shortly after I had pulled out of the way. A private jet [Aircraft Z] was holding short of Runway XY at the ramp at this point and also likely observed the situation. Given the size of the jet (wouldn't have fit in the small turn out at the end of Runway XY) and how the pilot never attempted a go-around; this could have been a real incident if it were the jet on the runway instead of me which is what concerns me. I received communications from the jet (jet that is based at ZZZ) that was holding short as well.After later talking with the operator; they did state the aircraft has no radios but insisted they were in the right.While landing aircraft have the right away; this aircraft was not yet in the pattern when I had began to back taxi. I believe they entered the pattern directly on a right base; making a right turn to final which was unexpected given this is a left traffic pattern. Furthermore; I was in a position where I could not easily turn my aircraft around and exit the runway which should've been clear from their view point; making a go-around the best option for the landing aircraft. Instead they proceeded to land; needlessly making a dangerous situation for the both of us.Ultimately nobody was injured but this entire scenario could have been mitigated by Aircraft Y following the established landing pattern; making himself more visible and giving any aircraft on the ground or the landing aircraft to take the appropriate evasive action.




Synopsis: Pilot reported an aircraft landed on the runway while he was still back taxiing to exit causing him to use 70 percent power to expedite clearing the runway.
