Thank you guys for your inputs   

I also got this from someone :

scp -r <username>@<raspberry_pi_ip>:/path/to/bitcoin/blocks /path/to/local/Downloads
scp -r <username>@<raspberry_pi_ip>:/path/to/bitcoin/chainstate /path/to/local/Downloads
scp -r <username>@<raspberry_pi_ip>:/path/to/bitcoin/indexes /path/to/local/Downloads

It requires the use of another strorage drive or some ssh connection to another machine to transfer data but that's the idea
I hope this can help others looking to avoid downloading the full blockchain again

Hello
I was testing Umbrel as I want to start learning how to run my Lightning network. I installed Umbrel on my Raspberry Pi4 and downloaded the BTC blockchain.
I have been running into few issues of stability with Umbrel and I am thinking of moving to another OS (it is part of the testing and learning)

So my question is how can I avoid formatting the hard drive and lose all the BTC blockchain I downloaded, if anyone has a procedure on how to back up the chain and copying it to a new OS install, that would be great! 

I tried to look for some guides but couldn't find a step by step one

Thanks for reading me...
