Hi mate, thanks for your response. I’m currently working on creating explorations, topics, classrooms, and other features for a mini project — a learning exploration platform for my college project. I’m using Docker, and as per the setup guide, I start the server with the command: Looking forward for your help, I really mean & appreciate it. Perhaps if you want to communicate via Whatsapp, Discord, or any other social platforms for more efficient communication, please kindly let me know. Thank you! |

Okay, so basically we don't store the data for the development environment. Once you stop the server, that data will vanish. The dev environment is used for feature development and bug fixes. Every time you start the server again, you need to create everything from scratch. What are you actually aiming for? This question might give us a broad perspective to help you out with this. If it is a non-tech project and you just want to create the explorations, you can use oppia.org, which will keep your data safe. |

Hi Hardik, thanks for the clarification. I’m using Oppia to build a learning platform for developers to learn cybersecurity materials — that’s the main goal of my project. In the end after creating all the explorations, etc, I want to host it into GCP, so all developers can access it internally. So far, I’ve created over 30 explorations, 10 topics, and 1 classroom. The data didn’t disappear when I stopped the server, since I had set SAVE_DATASTORE=true in my docker-compose.yml. Same with the firebase (user data), it didn't dissapear when I shut down the server. However, out of nowhere, all the topics and the classroom disappeared — but the explorations are still there. That made me wondering, "Where is all the data being stored?" So I asked my colleague to pull the files that i've been backing up to my local repository, and turns out the explorations weren't even there, but it's still here in my local laptop. Is it being saved on the docker container? What should I do now? I really don’t want to lose all my existing explorations. Please advise. Thanks in advance! |

@Dexsen88 as a temporary solution, can you try if backing up containers from the old machine and restoring it to new machine works. |

@jayam04, Thanks that could be a solution. Do you know which container on the docker that contains all the explorations and other datas? |

To start, I'd recommend moving all the containers. That way if the migration fails, we know the data is stored somewhere outside the containers. You can find the names of all the containers here: Line 6 in 5293e05 |

Hang on, so I need to move all the containers and restoring it to the new machine inside docker again? I don't think that will solve the problem mate. As I said, I’m planning to host this Oppia instance—with all my existing data—on a GCP server, so with or without docker that's fine, is there any solution for this? |

Hello, I’ve been running Oppia on WSL (Ubuntu 24.04) using Docker.
I’d like to ask where Oppia stores the data for explorations, topic and skill dashboards, classrooms, etc.
I backed up my local Oppia project — which contained many explorations, classrooms, and other data — but when I restored it on a different PC/laptop, the explorations no longer appear (even though they still show up in my dashboard).
Initially, I assumed the data was stored in datastore_data (specifically in the local_cb.bin file). I also tried mounting the Docker volumes in my docker-compose.yml file as follows:
./datastore_data:/app/cloud_datastore_emulator_cache
./firebase_data:/app/firebase_emulator_cache
However, the issue persists.
Could someone please help clarify where Oppia actually stores these data files and how I can correctly migrate or restore them? Thanks a lot.
