How do I fix randomly moved chunks after a crash?

Question

I was stupid and didn't keep a backup of my Minecraft server. Now, it crashed, biomes changed, chunks were moved around, part of my city of gone, an underground chunk was moved aboveground, is there ANY way I can fix this?

I.E. easily move chunks and change biomes.

Answer

They were moved because the map files got corrupt so it reads chunks in an out of place order.

It's like 1 2 3 4 5 6 7 8 9 would turn into 1 0 4 6 7 8 9 0 0, where 0 would be unreadable thus deleted.


Picking a known map editor should allow you to move chunks, they include terrain/forest generators.

And set up an automated back-up solution...
