Regenerating certain area

I have seen how to regenerate a world but I was wondering how would I regenerate a certain area? Like from X: 0, Z: 0 to X: 250, Z: 250

 

Store all block changes in that area, revert them.

 

RealDope What do you think the best place to store it to would be?

 

The RAM?

 

You asking how much ram my server has? It has 32 gb

 

No he is telling you where you would save it lol

 

RealDope Is this how I should store the blocks?

Code:java

@EventHandler
    public void onBlockBreakTwo(BlockBreakEvent evt) {
        if (isInSpawnTwo(evt.getBlock().getLocation())) {
            if(!(isInSpawn(evt.getBlock().getLocation()))) {
                plugin.getConfig().set("BrokenSpawnBlocks.", evt.getBlock());
            }
        }
    }

 

No, store them in the memory. Write to a file occasionally

 

If that's not going to work, you can also choose this way:
Get worldguard, make a region.
http://dev.bukkit.org/bukkit-plugins/regionstates/
Use regionstates and your console to let the region load from a backup.
(If you don't know how to use the console from your plugin )

Code:

Bukkit.getServer().dispatchCommand(Bukkit.getConsoleSender(), "[SIZE=13px][FONT=Andale Mono]regionstate[/FONT][/SIZE][SIZE=13px][FONT=Andale Mono]load[/FONT][/SIZE][SIZE=13px][FONT=Andale Mono]world_name[/FONT][/SIZE][SIZE=13px][FONT=Andale Mono]region_name[/FONT][/SIZE][SIZE=13px][FONT=Andale Mono]backup_name[/FONT][/SIZE]");

Enjoy
