I have an external drive where at some point I did a complete backup of my (linux) home directory.

There's a directory .bitcoin.

I now have a computer, and I just installed bitcoin-qt and other stuff. I started it and it generated a new receiver address.

If I copy the old .bitcoin directory from the external drive to my current new home, will it work?

  • I don't have any coins there, but I run a blog and I installed a wordpress plugin there some time ago which would publish a bitcoin address, in order to accept BTC donations. I could just change that address but I wondered. Feb 5, 2016 at 16:59
  • hmmm, after my own question here bitcoin.stackexchange.com/questions/42773/… I should be able to have an answer myself: actually running the whole wallet on the external DB :) Feb 5, 2016 at 17:53

To avoid any problem,in your source computer backup your private keys

bitcoind dumpprivkey

to answer your question, By default Bitcoin will put its data here:


I think the wallet is located in a file wallet.dat(https://en.bitcoin.it/wiki/Data_directory#Linux), so if you copy it, it will works.

fore a best security level, encrypt your wallet with a paraphrase before backaping it.
