Human Factors; Procedure
Taxiing out of ZZZZ we called the advisory frequency; we were told there was no inbound traffic and we were cleared to back taxi. It's about a 3;500 foot taxi to the end and roughly 1;000 feet from the end my First Officer points out what seems to be a Citation on a visual left base. We advise the VFR tower that there was an aircraft on final for our runway. Both the tower and ourselves attempted to tell the aircraft to go-around and failed. At this point there is brush and trees lining both sides of the runway and there was no turn off. I pull the aircraft to the right edge of the runway in event that he continued the landing. At an estimated 100 feet; the aircraft was seen adding power and retracting the gear. We advised the tower that we were clear of the conflict and we continued our departure.Suggestions: VFR island flying training or VFR plates to advise of traffic flows to certain airports.
Air Carrier pilot back taxiing at an international non-towered airport reported traffic not in CTAF communications was on approach to the same runway and initiated a go-around on short final.
