SpaceSMP Minecraft Backup System!

Would you like to know how to backup your Minecraft Server, in a way that follows the 3-2-1 backup technique?

The setup for this is really simple, all that is needed is:

• Syncthing setup on 2 devices. I recommend the docker container
• A Minecraft Server
• Thats it!
  Cost: Provided you already pay for a vps for your Minecraft server, you will only need one other device.

1. SSH into your server device

2. Open a new file in your home folder called backup.sh

    sudo nano ~/backup.sh
   

3. Put the following code inside the file

    SRC="Youre Minecraft Server Directory"
    DEST="Your Syncthing Source Directory"
   
    mkdir -p "$DEST"
   
    NEW_BACKUP="$DEST/world-$(date +%Y%m%d-%H%M%S)"
   
    rsync -avh --progress --exclude='bluemap/' "$SRC" "$NEW_BACKUP/"
   
    cd "$DEST" || exit
    ls -1dt world-* | tail -n +3 | xargs -r rm -rf
   

   This script copies your Minecraft Server Directory to your syncthing directory.

4. Open your cron file by running

    crontab -e
   

   Then add this line at the bottom:

    0 1 * * * /bin/bash ~/backup.sh
   

5. In your server’s management panel, set the server to run the command save-all 2 minutes before 1am.
6. Inside syncthing, setup syncing to your other server.
7. You’re done! Your server will now backup at 1am every day.

Thank you for reading ;)
