Hi! I love this! I’m having issues increasing the RAM usage though. I’m using a Raspberry Pi 4 (4GB). I’ve created an Environmental Variable of DOUBLE\_RAM and set it to TRUE. However, every time I start my server it says “Starting jar file with: 1G of RAM”. I also get a lot of warnings that the server is overloaded and can’t keep up. Any thoughts? ---

@ate4110 welcome to the forum! To prevent anyone asking me to make a var which sets a much bigger amount of RAM i deleted the old one and made a completely new system for the RAM: [https://github.com/AlexProgrammerDE/balena-minecraft-server#custom-ram-optional-link](https://github.com/AlexProgrammerDE/balena-minecraft-server#custom-ram-optional-link) ---

So, for example, I would create a variable called “RAM” and set the value to “2GB”? Is the syntax correct? Is this an environmental variable? Thank you so much for the help ---

The value should be 2G . And yes its an enviromental variable. ---

I ran into that problem myself last night. make sure your mc-server/serverfiles/server.properties has these 3 lines: ` rcon.port=25575 enable-rcon=true rcon.password=balena ` if you have already spun up your server you can edit the server properties using [winscp/filezilla](https://github.com/AlexProgrammerDE/balena-minecraft-server#connect-to-the-file-directory-satellite) if you do modify the server.properties file remember to restart the mc-server Join the game on your minecraft server then while still connected use an RCON program as described [here](https://github.com/AlexProgrammerDE/balena-minecraft-server#connect-to-the-terminal-satellite) the command you will need to send is: ` op your-minecraft-username ` ---

Hi there! First of all, thanks soo much for creating this project! I’ve been looking for an easy way to setup a Dedicated Minecraft server on my Raspberry Pi 4 (8GB) for ages, and this is the first method that seems to be ridiculously easy to use. I’ve gotten as far as getting the default project to run on my server, but I need to use Forge 1.12.2, which of course requires Java-8 rather than 11. Furthermore, I’ve noticed that the system seems to be hard-coded to use the latest vanilla jar files and paper. Are there any Device Service variables I could use to specify the JDK and jar file to be used? I am attempting to experiment with ways to do this in the meantime, but any help on the matter would be welcome. Thanks in advance! ---

I also had problem with 8GB raspi4, but worked like a charm with the 4GB version. looks like there is an issue to find a proper image for a 8GB raspi4.

Thanks for a great project. Forced me to learn balena and give up the idea to proceed with ansible 🙂 … Enjoying it with my kids now 🙂 … One question: did you think of some world backup procedure ? Balena does not offer it out of the box. And knowing how unreliable raspi on SD is the idea of losing our world is haunting me 🙂 … Would be grateful for any advice. Since i’m new to minecraft game/servers at least telling which files I need to backup would help a lot 🙂 I’ll google for paper server backup procedures for now 🙂 ---

I too would be interested in this. We started of with my boys, using 1.15.2. When the clients upgraded to 1.16 I was forced to reinstall everything from scratch to the RPi4 as I found no means to save - if it was possible at all. Obviously this felt the boys sad, but we restarted. Now I am wondering how to restart a new map? And is it possible to use a seed for a new map. Apart from this, kudos to Alex, I really love this project of his! 🙂 ---

Thanks, Alex. I already got it done, by reinstalling manually. BUT, is there a way to start a new map, without a full re-install? Maybe a terminal command, or just a parameter and then reboot? And could the server start a new map using a seed? (I need to get a map, the kids like - they gave me this as homework :-)) [Previous page](https://forums.balena.io/t/my-project-balena-minecraft-server/58552.md?page=1) [Next page](https://forums.balena.io/t/my-project-balena-minecraft-server/58552.md?page=3)
