Saving all objects on a map? Server-side.

[esphaglion]

Hello!

I would like to save all objects on a map if I want to. I'm one of the administrators of my server.
The objects should be on the same position as they were before a restart.

The server runs on a dedicated server-machine so 24/7 server running would not be the problem but updating add-ons and server crashes are.

Is there a plugin which helps me to do that? The AdvancedDuplicator from the Wire-modification is not an alternative for me.
I would like to save the current map-state like in the Singleplayer game.

Every help will be appreciated!

Thanks in advance!

Greetings
