This is a new tool I've coded to prevent world loss on any minecraft server. I recently created a modded server, but decided to take a mod out after making the world, and the world became unusable. My tool aims to prevent world corruption due to new plugins, mods, or to keep another copy of your world just in case something goes wrong. This tool works with any minecraft server, vanilla, bukkit, or forge, and works with all minecraft versions.
To use my tool
Step 1. Download the Backup.exe file below and place it in your server folder next to the minecraft_server.jar.
Step 2. Open your run.bat and add "backup" to the batch file on the first line. It should look something like this.
backup
java -Xmx1024m -Xms512m -jar minecraft_server.jar
pause
Step 3. Run the server and input the name of your world folder when prompted, By default it should be "world".
