Urgent help needed, server crash/map corruption

Im getting the following error.

EDIT: The error is from a 1.5_02 client

I wouldn't worry about that while people are connecting. Seems the 1.5_2 has been doing that with both Vanilla and the recent bukkit versions. Some of it appears to be player position or movement...

As far as the corrupt map, unless you have a backup there is not alot you can do unless you happen to know the map seed.

The way to know for sure is to travel towards unexplored regions and look for serious terrain mix ups. Usually they are very obvious.. If you find this, it is basicly the level.dat generating terrain with a new seed. I've seen this happen with unstable bukkit versions (but not lately) and i've seen it hands down any time a server looses power.

Best thing, is take the seed and regenerate the map, make schematics of anything specific, or entire sections of non corrupt terrain, or even the chunks if your daring, and paste it all back into the map proper.

One of these days i'm going to try and insert the seed back into the map, delete the bad chunks, and see how well it turns out, but havn't tried that yet.

Always back up. BACKUP!

 

^^^^^^^^^^^^^^^^^^^^^^ is that not the law of mc>???????????????

 

What do you use for your backups? Manual copy of the world or a plugin? or some sort of a script? Whatever it is...I'd like it if you could tell me what you use...

 

I use 2 forms usually- manual and via plugin.. I keep intending to setup backup/synch otherwise to capture the entire server folder but... Check the 'get plugins' and look up backup. Those are good options, however i've seen them all crashing with the newer bukkit builds so i'd suggest letting them update before relying on them.

 

This is on build 556. Anyways i do backup with a shell script i threw together, i can put my server back just fine. I want to eliminate the problem from occurring again.

 

i do it by myself atm, i have like 10 flash frives so if pc crash im set

 

Well it's been a while, has"One of these days" come? My map's broken, and I do not want to loos the work I've done on it. could use some pointers on how to do the surgical removal of bad chunks or preservation of specific chunks to be imported later after reseeding map. Any help some anyone can provide will be most useful and greatly appreciated.
