What is the best way to backup the seed of a minecraft server? I'm getting ready to set up a "permanent" world after the full minecraft version is released, and I want to do everything possible to prevent both world block corruption and world seed corruption.

Correct me if I'm wrong, but won't your spawn be different if you restore a map with just a seed? Besides, seeds are just numbers. Store it in a text file or something. – Maxpm Oct 28 '11 at 20:34
I want to be able to restore the seed so the server won't get the "fail cliffs" where the seed get corrupted whenever the server crashes. I already have tools to move the spawn, but the seed is a different story. =) – Kenneth Posey Oct 28 '11 at 20:54
Your question doesn't really make sense to me. The abrupt terrain transitions and biome corruptions are caused by the terrain generator being changed with an update. If you generate a new map using the same seed, it'll be completely different. – a cat Oct 28 '11 at 21:06
@lunboks is correct. In my SSP game, the value of the seed hasn't changed, yet because it's been through numerous updates, my world has some abrupt edges. 2 worlds generated with the same seed, one from 1.4 say and the other from 1.9 won't look anything alike, even neglecting things like biomes and NPC villages. – MBraedley Oct 29 '11 at 16:17
@MBraedley, I have many cliffs of mojang or whatever you would like to call them in my current world, but I don't recall whether that occurred between versions of the game or not as I wasn't doing the exploring. For now I'll take his word for it. =) – Kenneth Posey Oct 30 '11 at 1:01

The seed is just a number in the file. You can see the seed value of the world in the client now, and when you set up a permanent server, add it into there so you dont get the cliffs of mojang when generating new chunks.
