Duplicating BitcoinCore reorg

[harlequininja]

I'm running a full nod and I'd like to get another one running.
Is it possible to somehow just duplicate the database of the first node?
I guess this question has already been asked on the forum.

I see no reason why not. Copy the data dir (see https://en.bitcoin.it/wiki/Data_directory ) on the new computer.
You can use similar structure or you can run with -datadir parameter.

The database files in the "blocks" and "chainstate" directories are cross-platform, and can be copied between different installations.

Will give it a go 
Thank you for the wiki-entry, was very helpful.

peers.dat does not have any personally identifiable information because this information is serialized from (ultimately) CNode which only contains addresses and some other connection stats, and its also used to display the GUI tables of peers such as this one. This statement on the wiki will be adjusted accordingly.

Copy indexes too, if you're running Bitcoin Core with txindex=1. If you're at linux, be careful not to screw it up with user permissions. This line is all that's needed:

Code:

cp -r blocks chainstate indexes <destination_directory>

You run it twice; one from your node to a hard drive, and the second from your hard drive to your other computer.
