## I have the full blockchain on another computer. How do I copy it to the RaspiBlitz?
|
||||
|
||||
Copying a already synced blockchain from another computer (for example your Laptop) can be a quick way to get the RaspiBlitz started. Also that way you synced and verified the blockchain yourself and not trusting the RaspiBlitz FTP/Torrent downloads (dont trust, verify).
|
||||
|
||||
One requirement is that the blockchain is from another bitcoin-core client with version greater or equal to 0.17.1 with transaction index switched on (`txindex=1` in the `bitcoin.conf`).
|
||||
|
||||
But we dont copy the data via USB to the device, because the HDD needs to be formatted in EXT4 and that is usually not read/writeable by Windows or Mac computers. So I will explain a way to copy the data thru your local network. This should work from Windows, Mac, Linux and even from another already synced RaspiBlitz.
|
||||
|
||||
Both computers (your RaspberryPi and the other computer with the full blockchain on) need to be connected to the same local network. Start the setup of the RaspiBlitz with a fresh SD card like explained in the README - its OK that there is no blockchain data on your HDD. At the point of the Setup about `Getting the Blockchain` choose the COPY option. Starting from version 1.0 of the RaspiBlitz this will give you further detailed instructions how to transfere the blockchain data onto your RaspiBlitz. In short: On your computer with the blockchain data you will execute SCP commands, that will copy the data over to your RaspiBlitz.
|
||||
|
||||
Once you finsihed the transfere the Raspiblitz will make a quick check - but beware that if there is an error during transfere it can result that yo

## How to backup my Lightning Node?

|

CAUTION: Restoring a backup can lead to LOSS OF ALL CHANNEL FUNDS if its not the latest channel state. There is no perfect backup solution for lightning nodes yet - this topic is in development by the community.

|
||||
|

But you can try to backup at your own risk. All your Lightning Node data is within the `/mnt/hdd/lnd` directory. Just run a backup of that data when the lnd service is stopped.

|
||||
## How do I change the Name/Alias of my lightning node
|
||||
|
||||
Use the "Change Name/Alias of Node" option in main menu. The RaspiBlitz will make a reboot after this.
