Minecraft world copy / part of a world?

Ja

So I play with my girlfriend on a world and have built quite a lot.

However, apparently two worlds have now overlapped?!

Now I would like to copy the WHOLE area which we have already explored and which does not overlap simply on the same seed in a fixed world. In terms of size, it's almost a whole biome.

Is that somehow possible?

I know you can copy buildings etc. With Worldedit. However, Minecraft smears on the huge area.

Can I do it any other way or maybe reload the world so that the areas that do not belong in it are gone again?

If you have backed up the world or "Auto backed up" before it overlapped, you can load the backup from back then. However, buildings that you have made in between are gone. Would be an option!

Possibly. Copy with Worldedit what you did after the backup and load it into the "old" world if it is not too much that your PC smeared.
