So there's this planet that, several decades earlier, suffered a massive famine and drought that made habitation impossible. Everyone still alive on this planet died, except for 2 escapees, both of which have just recently died. The planet is around the size of Earth's moon and, at its peak, had a population of around 5 million. The planet's civilization was culturally and technologically based on Ancient Egypt and the entire planet is a desert.
So here's what's happening now: The drought on the planet has long since ended. The government of Ishgabangaloodoo (a planet with Victorian British culture but Star Wars-level technology) has decided that someone needs to be around to maintain this planet's culture and prevent the planet from being used as a smuggler hideout. They sent a team of archaeologists to the planet, where they got DNA samples from some of the mummified corpses.
If the Ishgas were to clone, say 1,000 of these people, assuming that most genetic defects are edited out of the clones' DNA, how long would it take for this planet to repopulate to its historical 5 million?
Note: the inhabitants of this planet have essentially human physiology.
