I’ve been running bitcoin node on my umbrel for the past couple of months. But I have been unable to access my umbrel for the past couple of weeks for some reason. This has happened before as well and I reinstalled umbrel and re-downloaded the whole blockchain one more time. But I don’t want to do that again. I am thinking of running bitcoin node on ubuntu but don’t want to re-download the blockchain. Is there a guide on how I can use _the existing blockchain data on external SSD used for running bitcoin node on umbrel_ on Ubuntu? If there’s someone else out there who has done such before please help out. ---

Here’s a great guide! Please let me know if you have any questions or require any assistance > [@Official Umbrel Troubleshooting Guide and FAQ](https://community.umbrel.com/t/official-umbrel-troubleshooting-guide-and-faq/9873/1): > > **How to Synchronize a New Bitcoin Node from an Existing One** > > Advanced users can take advantage of the following methods to synchronize a new node with an existing one. Please be cautious as these methods are not natively supported in Umbrel. > > _Method 1: Transferring Blockchain Data_ > > The steps below are for copying data from an existing Linux machine to a new Raspberry Pi, but the steps are similar for other combinations of devices. > > 1. Flash UmbrelOS to a microSD card and boot the Raspberry Pi with your SSD attached. > 2. Complete the Umbrel setup process. Your SSD will now be formatted for Umbrel use. > 3. Go to the settings page and shut down Umbrel. > 4. Remove the SSD and attach it to a Linux machine with the full blockchain. > 5. Copy the blocks and chainstate directories on the Linux machine to `~/umbrel/app-data/bitcoin/data/bitcoin` directory on the SSD. > 6. Remove the SSD from your Linux machine, plug it back into your Raspberry Pi, and power it back on. > > _Method 2: Direct Synchronization_ > > This method allows you to sync your new node from another running Bitcoin node on the same network or trusted connection, without the need to copy data to a different device. > > 1. Connect to your Umbrel device by following the instructions in _How to SSH into umbrelOS on Umbrel Home or Rasberry Pi_ or by accessing a terminal on your Linux machine. > 2. Run the following command\*. If you are on a Linux machine, you may need to replace `~/umbrel` with the path to your installation directory, as described in _Troubleshooting on Linux_:`sudo ~/umbrel/scripts/app compose bitcoin exec bitcoind bitcoin-cli addnode "192.168.x.x:8333" "onetry"`\*Replace “192.168.x.x” with the IP of the existing running node. > > Once your new node is fully synced, you can safely remove the IP from peers and go back to a normal connection. For more information, see [https://chainquery.com/bitcoin-cli/addnode](https://chainquery.com/bitcoin-cli/addnode). ---

Isn’t this for running a new node on umbrel instead of running on any other distro? ---

Both methods should work for you. Technically you only need the first 3-4 instructions of method 1 for your new node, and then you can point core to that directory.
